Field Summary

Fields

Modifier and Type	Field and Description
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.

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.

Constructor Detail

FixedNsContext

private FixedNsContext(NsDeclaration lastDecl,
                       java.lang.String[] declData)

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.
