Object that stores information about currently accessible attributes.
-
mStDoctypeFound
protected boolean mStDoctypeFound
-
mTokenState
protected int mTokenState
State of the current token; one of M_ - constants from above.Initially set to fully tokenized, since it's the virtual START_DOCUMENT event that we fully know by now (parsed by bootstrapper)
-
mStTextThreshold
protected final int mStTextThreshold
Threshold value that defines tokenization state that needs to be achieved to "finish" current logical text segment (which may consist of adjacent CDATA and text segments; or be a complete physical segment; or just even a fragment of such a segment)
-
mCurrTextLength
protected int mCurrTextLength
Sized of currentTextLength for CDATA, CHARACTERS, WHITESPACE. When segmenting, this records to size of all the segments so we can track if the text length has exceeded limits.
-
mStEmptyElem
protected boolean mStEmptyElem
-
mParseState
protected int mParseState
Main parsing/tokenization state (STATE_xxx)
-
mCurrToken
protected int mCurrToken
Current state of the stream, ie token value returned bygetEventType(). Needs to be initialized to START_DOCUMENT, since that's the state it starts in.
-
mSecondaryToken
protected int mSecondaryToken
Additional information sometimes stored (when generating dummy events in multi-doc mode, for example) temporarily whenmCurrTokenis already populated.
-
mWsStatus
protected int mWsStatus
Status of current (text) token's "whitespaceness", that is, whether it is or is not all white space.
-
mValidateText
protected boolean mValidateText
Flag that indicates that textual content (CDATA, CHARACTERS) is to be validated within current element's scope. Enabled if one of validators returnsXMLValidator.CONTENT_ALLOW_VALIDATABLE_TEXT, and will prevent lazy parsing of text.

mCheckIndentation
protected int mCheckIndentation
Counter used for determining whether we are to try to heuristically "intern" white space that seems to be used for indentation purposes
-
mPendingException
protected javax.xml.stream.XMLStreamException mPendingException
Due to the way Stax API does not allow throwing stream exceptions from many methods for which Woodstox would need to throw one (especiallygetTextand its variations), we may need to delay throwing an exception untilnext()is called next time. If so, this variable holds the pending stream exception.
-
mGeneralEntities
protected java.util.Map<java.lang.String,EntityDecl> mGeneralEntities
Entities parsed from internal/external DTD subsets. Although it will remain null for this class, extended classes make use of it, plus, to be able to share some of entity resolution code, instance is left here even though it semantically belongs to the sub-class.
-
mVldContent
protected int mVldContent
Mode information needed at this level; mostly to check what kind of textual content (if any) is allowed in current element context. Constants come fromXMLValidator, (likeXMLValidator.CONTENT_ALLOW_VALIDATABLE_TEXT). Only used inside tree; ignored for prolog/epilog (which have straight-forward static rules).

- Token to return
- Throws:
javax.xml.stream.XMLStreamException
-
handleMultiDocStart
protected int handleMultiDocStart(int nextEvent)

Works similar to attribute value parsing, except no entities can be included, and in general need not be as picky (since caller is to verify contents). One exception is that we do check for linefeeds and lt chars, since they generally would indicate problems and are useful to catch early on (can happen if a quote is missed etc)Note: since it'll be called at most 3 times per document, this method is not optimized too much.
- Throws:
javax.xml.stream.XMLStreamException
-
nextFromPrologBang
private void nextFromPrologBang(boolean isProlog) throws javax.xml.stream.XMLStreamExceptionCalled after character sequence '<!' has been found; expectation is that it'll either be DOCTYPE declaration (if we are in prolog and haven't yet seen one), or a comment.

javax.xml.stream.XMLStreamException
-
startDTD
private void startDTD() throws javax.xml.stream.XMLStreamExceptionMethod called to parse through most of DOCTYPE declaration; excluding optional internal subset.- Throws:
javax.xml.stream.XMLStreamException
-
finishDTD
protected void finishDTD(boolean copyContents) throws javax.xml.stream.XMLStreamExceptionThis method gets called to handle remainder of DOCTYPE declaration, essentially the optional internal subset. This class implements the basic "ignore it" functionality, but can optionally still store copy of the contents to the read buffer.NOTE: Since this default implementation will be overridden by some sub-classes, make sure you do NOT change the method signature.
- Parameters:
copyContents- If true, will copy contents of the internal subset of DOCTYPE declaration in the text buffer; if false, will just completely ignore the subset (if one found).- Throws:
javax.xml.stream.XMLStreamException
-

private int closeContentTree() throws javax.xml.stream.XMLStreamExceptionMethod called when advancing stream past the end tag that closes the root element of the open document. Document can be either the singular one, in regular mode, or one of possibly multiple, in multi-doc mode: this method is never called in fragment mode. Method needs to update state properly and parse following epilog event (if any).- Returns:
- Event following end tag of the root elemennt, if any; END_DOCUMENT otherwis.e
- Throws:
javax.xml.stream.XMLStreamException
-
handleStartElem

-
nextFromTreeCommentOrCData
private int nextFromTreeCommentOrCData() throws javax.xml.stream.XMLStreamExceptionNote: According to StAX 1.0, coalesced text events are always to be returned as CHARACTERS, never as CDATA. And since at this point we don't really know if there's anything to coalesce (but there may be), let's convert CDATA if necessary.
- Throws:
javax.xml.stream.XMLStreamException
-
skipToken
private int skipToken() throws javax.xml.stream.XMLStreamExceptionMethod called to skip last part of current token, when full token has not been parsed. Generally happens when caller is not interested in current token and just calls next() to iterate to next token.Note: this method is to accurately update the location information to reflect where the next event will start (or, in case of EOF, where EOF was encountered, ie. where event would start, if there was one).
- Returns:
- Next character after node has been skipped, or -1 if EOF follows
- Throws:
javax.xml.stream.XMLStreamException
-
skipCommentOrCData

private final boolean readCDataPrimary(char c) throws javax.xml.stream.XMLStreamExceptionMethod called to read in consecutive beginning parts of a CDATA segment, up to either end of the segment (]] and >) or until first 'hole' in text (buffer end, 2-char lf to convert, entity).When the method is called, it's expected that the first character has been read as is in the current input buffer just before current pointer
- Parameters:
c- First character in the CDATA segment (possibly part of end marker for empty segments- Returns:
- True if the whole CDATA segment was completely read; this happens only if lt-char is hit; false if it's possible that it wasn't read (ie. end-of-buffer or entity encountered).
- Throws:
javax.xml.stream.XMLStreamException
-
readCDataSecondary
protected boolean readCDataSecondary(int shortestSegment) throws javax.xml.stream.XMLStreamException- Returns:
- True if the whole CData section was completely read (we hit the end marker); false if a shorter segment was returned.
- Throws:
javax.xml.stream.XMLStreamException
-
checkCDataEnd
private boolean checkCDataEnd(char[] outBuf, int outPtr) throws javax.xml.stream.XMLStreamExceptionMethod that will check, given the starting ']', whether there is ending ']]>' (including optional extra ']'s); if so, will updated output buffer with extra ]s, if not, will make sure input and output are positioned for further checking.- Returns:
- True, if we hit the end marker; false if not.
- Throws:
javax.xml.stream.XMLStreamException
-
readTextPrimary
private final boolean readTextPrimary(char c) throws javax.xml.stream.XMLStreamExceptionMethod called to read in consecutive beginning parts of a text segment, up to either end of the segment (lt char) or until first 'hole' in text (buffer end, 2-char lf to convert, entity).When the method is called, it's expected that the first character has been read as is in the current input buffer just before current pointer
- Parameters:
c- First character of the text segment- Returns:
- True if the whole text segment was completely read; this happens only if lt-char is hit; false if it's possible that it wasn't read (ie. end-of-buffer or entity encountered).
- Throws:
javax.xml.stream.XMLStreamException
-
readTextSecondary
protected final boolean readTextSecondary(int shortestSegment, boolean deferErrors) throws javax.xml.stream.XMLStreamException- Parameters:
deferErrors- Flag to enable storing an exception to a variable, instead of immediately throwing it. If true, will just store the exception; if false, will not store, just throw.- Returns:
- True if the text segment was completely read (
'<'was hit, or in non-entity-expanding mode, a non-char entity); false if it may still continue - Throws:
javax.xml.stream.XMLStreamException
-

readIndentation
private final int readIndentation(char c, int ptr) throws javax.xml.stream.XMLStreamExceptionMethod called to try to parse and canonicalize white space that has a good chance of being white space with somewhat regular structure; specifically, something that looks like typical indentation.Note: Caller guarantees that there will be at least 2 characters available in the input buffer. And method has to ensure that if it does not find a match, it will return pointer value such that there is at least one valid character remaining.
- Returns:
- -1, if the content was determined to be canonicalizable (indentation) white space; and thus fully parsed. Otherwise pointer (value to set to mInputPtr) to the next character to process (not processed by this method)
- Throws:
javax.xml.stream.XMLStreamException
-
readSpacePrimary
private final boolean readSpacePrimary(char c, boolean prologWS) throws javax.xml.stream.XMLStreamExceptionReading whitespace should be very similar to reading normal text; although couple of simplifications can be made. Further, since this method is very unlikely to be of much performance concern, some optimizations are left out, where it simplifies code.- Parameters:
c- First white space characters; known to contain white space at this pointprologWS- If true, is reading white space outside XML tree, and as such can get EOF. If false, should not get EOF, nor be followed by any other char than <- Returns:
- True if the whole white space segment was read; false if something prevented that (end of buffer, replaceable 2-char lf)
- Throws:
javax.xml.stream.XMLStreamException
-
readSpaceSecondary
private void readSpaceSecondary(boolean prologWS) throws javax.xml.stream.XMLStreamExceptionThis is very similar to readSecondaryText(); called when we need to read in rest of (ignorable) white space segment.- Parameters:
prologWS- True if the ignorable white space is within prolog (or epilog); false if it's within xml tree.- Throws:
javax.xml.stream.XMLStreamException
-
readAndWriteText
private int readAndWriteText(java.io.Writer w) throws java.io.IOException, javax.xml.stream.XMLStreamExceptionMethod called to read the contents of the current CHARACTERS event, and write all contents using the specified Writer.- Parameters:
w- Writer to use for writing out textual content parsed- Returns:
- Total number of characters written using the writer
- Throws:
java.io.IOExceptionjavax.xml.stream.XMLStreamException
-
readAndWriteCData
private int readAndWriteCData(java.io.Writer w) throws java.io.IOException, javax.xml.stream.XMLStreamExceptionMethod called to read the contents of the current (possibly partially read) CDATA event, and write all contents using the specified Writer.- Parameters:
w- Writer to use for writing out textual content parsed- Returns:
- Total number of characters written using the writer for the current CDATA event
- Throws:
java.io.IOExceptionjavax.xml.stream.XMLStreamException
-
readAndWriteCoalesced
private int readAndWriteCoalesced(java.io.Writer w, boolean wasCData) throws java.io.IOException, javax.xml.stream.XMLStreamException- Returns:

- Throws:
java.io.IOExceptionjavax.xml.stream.XMLStreamException
-
skipWS
protected final boolean skipWS(char c) throws javax.xml.stream.XMLStreamExceptionMethod that will skip any white space from input source(s)- Returns:
- true If at least one white space was skipped; false if not (character passed was not white space)
- Throws:
javax.xml.stream.XMLStreamException
-
