Method Summary

Modifier and TypeMethod and Description
public void
addVariable(VariableRefBase variableRef)

Implements com.sun.org.apache.xalan.internal.xsltc.compiler.Closure.addVariable.

Add new variable to the closure.

private void
compileConstructor(ClassGenerator classGen)

Compiles a constructor for the class _className that inherits from {Any,Single,Multiple}NodeCounter.

private void
compileDefault(ClassGenerator classGen, MethodGenerator methodGen)

private void
compileLocals(NodeCounterGenerator nodeCounterGen, MatchGenerator matchGen, InstructionList il)

This method compiles code that is common to matchesFrom() and matchesCount() in the auxillary class.

private void

public String
getInnerClassName()

Implements com.sun.org.apache.xalan.internal.xsltc.compiler.Closure.getInnerClassName.

Returns the name of the auxiliary class or null if this predicate is compiled inside the Translet.

public Closure
getParentClosure()

Implements com.sun.org.apache.xalan.internal.xsltc.compiler.Closure.getParentClosure.

public boolean
inInnerClass()

Implements com.sun.org.apache.xalan.internal.xsltc.compiler.Closure.inInnerClass.

Returns true if this closure is compiled in an inner class (i.e. if this is a real closure).

public boolean
isDefault()

Returns true if this instance of number has neither a from nor a count pattern.

public void
parseContents(Parser parser)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.parseContents.

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.parseContents.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.parseContents.
