Package com.ctc.wstx.sr

Class CompactNsContext

java.lang.Object

com.ctc.wstx.util.BaseNsContext

com.ctc.wstx.sr.CompactNsContext

All Implemented Interfaces:

NamespaceContext

public final class CompactNsContext
extends BaseNsContext

Simple implementation of separate non-transient namespace context object. Created for start-element event by transient namespace instance updated by stream reader.

Note about implementation: Location information is only needed (and only needs to passed) if access is made via extended interface; one that can return information about actual Namespace event objects.

Field Summary

Fields

Modifier and Type	Field	Description
(package private) final int	mFirstLocalNs	Index of first namespace pair in mNamespaces that is declared in scope of element for which this context was constructed.
(package private) final Location	mLocation
(package private) final String[]	mNamespaces	Array that contains 2 Strings for each declared default namespace (including default namespace declarations); first is the prefix, second URI.
(package private) final int	mNsLength	Number of entries in mNamespaces (which is twice the number of bindings)
(package private) ArrayList<Namespace>	mNsList	List only needed to support List accessor from start-element event; created lazily if/as needed.

Field Details

mLocation

final Location mLocation

mNamespaces

final String[] mNamespaces

Array that contains 2 Strings for each declared default namespace (including default namespace declarations); first is the prefix, second URI.

mNsLength

final int mNsLength

Number of entries in mNamespaces (which is twice the number of bindings)

mFirstLocalNs

final int mFirstLocalNs

Index of first namespace pair in mNamespaces that is declared in scope of element for which this context was constructed. May be equal to mNsLength (which indicates there are no local bindings).

mNsList

transient ArrayList<Namespace> mNsList

List only needed to support List accessor from start-element event; created lazily if/as needed.

 String[] namespaces,
 int nsLen,
 int firstLocal)

Method Details

doGetNamespaceURI

public String doGetNamespaceURI(String prefix)

Specified by:

doGetNamespaceURI in class BaseNsContext

Parameters:

prefix - Non-null, non-empty prefix (base-class verifies these constraints) to find namespace URI for.

doGetPrefix

public String doGetPrefix(String nsURI)

Specified by:

doGetPrefix in class BaseNsContext

doGetPrefixes

public Iterator<String> doGetPrefixes(String nsURI)

Specified by:

doGetPrefixes in class BaseNsContext

getNamespaces

public Iterator<Namespace> getNamespaces()

Specified by:

getNamespaces in class BaseNsContext

outputNamespaceDeclarations

public void outputNamespaceDeclarations(Writer w)
                                 throws IOException

Method called by CompactStartElement to output all 'local' namespace declarations active in current namespace scope, if any. Local means that declaration was done in scope of current element, not in a parent element.

Specified by:

outputNamespaceDeclarations in class BaseNsContext

Throws:

IOException

outputNamespaceDeclarations

public void outputNamespaceDeclarations(XMLStreamWriter w)
                                 throws XMLStreamException

Specified by:

outputNamespaceDeclarations in class BaseNsContext

Throws:

XMLStreamException
