Package com.fasterxml.aalto.in

Class ByteBasedScanner

java.lang.Object

com.fasterxml.aalto.in.XmlScanner

com.fasterxml.aalto.in.ByteBasedScanner

All Implemented Interfaces:

XmlConsts, NamespaceContext, XMLStreamConstants

Direct Known Subclasses:

AsyncByteScanner, StreamScanner

public abstract class ByteBasedScanner
extends XmlScanner

Intermediate base class used by different byte-backed scanners. Specifically, used as a base by both blocking (stream) and non-blocking (async) byte-based scanners (as opposed to Reader-backed, character-based scanners)

                         throws XMLStreamException

Specified by:

getEndingByteOffset in class XmlScanner

Throws:

XMLStreamException

getEndingCharOffset

public long getEndingCharOffset()
                         throws XMLStreamException

decodeCharForError

protected abstract int decodeCharForError(byte b)
                                   throws XMLStreamException

Method called by methods when encountering a byte that can not be part of a valid character in the current context. Should return the actual decoded character for error reporting purposes.

Throws:

XMLStreamException

addUTFPName

protected final PName addUTFPName(ByteBasedPNameTable symbols,
 XmlCharTypes charTypes,
 int hash,
 int[] quads,
 int qlen,
 int lastQuadBytes)
                           throws XMLStreamException

Conceptually, this method really does NOT belong here. However, currently it is quite hard to refactor it, so it'll have to stay here until better place is found

Throws:

XMLStreamException

reportInvalidInitial

protected void reportInvalidInitial(int mask)
                             throws XMLStreamException
