Class FixedNsContext

java.lang.Object
  com.fasterxml.aalto.in.FixedNsContext

All Implemented Interfaces:

javax.xml.namespace.NamespaceContext

public final class FixedNsContext
extends java.lang.Object
implements javax.xml.namespace.NamespaceContext

Non-transient implementation of NamespaceContext.

Field Summary

protected java.lang.String[]	_declarationData Array that contains prefix/namespace-uri pairs, ordered from the most recent declaration to older ones.
protected NsDeclaration	_lastDeclaration We will keep a reference to the last namespace declaration in effect at point when this instance was created.
protected java.util.ArrayList<java.lang.String>	_tmpDecl Temporary List used for constructing compact namespace binding information that we will actually use.
static FixedNsContext	EMPTY_CONTEXT We can share and reuse "no bindings" instance.

Method Summary

java.lang.String	getNamespaceURI(java.lang.String prefix)
java.lang.String	getPrefix(java.lang.String nsURI)
java.util.Iterator<?>	getPrefixes(java.lang.String nsURI)
FixedNsContext	reuseOrCreate(NsDeclaration currLastDecl) Method called to either reuse this context or construct a new one.
java.lang.String	toString()

Field Detail

EMPTY_CONTEXT

public static final FixedNsContext EMPTY_CONTEXT

We can share and reuse "no bindings" instance.

_lastDeclaration

protected final NsDeclaration _lastDeclaration

We will keep a reference to the last namespace declaration in effect at point when this instance was created. This is used for lazy invalidation of instances: if last declaration for an instance differs from the last seen by the reader, a new context must be created.

_declarationData

protected final java.lang.String[] _declarationData

Array that contains prefix/namespace-uri pairs, ordered from the most recent declaration to older ones. Array is always exactly sized so there are no empty entries at the end.

_tmpDecl

protected java.util.ArrayList<java.lang.String> _tmpDecl

Temporary List used for constructing compact namespace binding information that we will actually use.

Method Detail

reuseOrCreate

public FixedNsContext reuseOrCreate(NsDeclaration currLastDecl)

Method called to either reuse this context or construct a new one. Reuse is ok if the currently active last declaration has not changed since time this instance was created.
