Class CompactNsContext

java.lang.Object

com.ctc.wstx.util.BaseNsContext

com.ctc.wstx.sr.CompactNsContext

All Implemented Interfaces:

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

Field Detail

mLocation

final javax.xml.stream.Location mLocation

mNamespaces

final java.lang.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 java.util.ArrayList<javax.xml.stream.events.Namespace> mNsList

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

Constructor Detail

CompactNsContext

public CompactNsContext(javax.xml.stream.Location loc,
                        java.lang.String[] namespaces,
                        int nsLen,
                        int firstLocal)

Method Detail

doGetNamespaceURI

public java.lang.String doGetNamespaceURI(java.lang.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 java.lang.String doGetPrefix(java.lang.String nsURI)

Specified by:

doGetPrefix in class BaseNsContext

doGetPrefixes

public java.util.Iterator<java.lang.String> doGetPrefixes(java.lang.String nsURI)

Specified by:

doGetPrefixes in class BaseNsContext

getNamespaces

public java.util.Iterator<javax.xml.stream.events.Namespace> getNamespaces()

Specified by:

getNamespaces in class BaseNsContext

outputNamespaceDeclarations

public void outputNamespaceDeclarations(java.io.Writer w)
                                 throws java.io.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:

java.io.IOException

outputNamespaceDeclarations

public void outputNamespaceDeclarations(javax.xml.stream.XMLStreamWriter w)
                                 throws javax.xml.stream.XMLStreamException

Specified by:

outputNamespaceDeclarations in class BaseNsContext

Throws:

javax.xml.stream.XMLStreamException
