Method Summary

Modifier and TypeMethod and Description
public boolean
contextDependent()

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

Returns true if this expression/instruction depends on the context.

public boolean
getValue()

public String
toString()

Implements abstract com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.toString.

Returns a string representation of the object.

public void
translate(ClassGenerator classGen, MethodGenerator methodGen)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translate.

Translate this node into JVM bytecodes.

public void
translateDesynthesized(ClassGenerator classGen, MethodGenerator methodGen)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translateDesynthesized.

Redefined by expressions of type boolean that use flow lists.

public Type
typeCheck(SymbolTable stable)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.typeCheck.

Type check all the children of this node.

public boolean contextDependent()

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

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

Returns true if this expression/instruction depends on the context. By default, every expression/instruction depends on the context unless it overrides this method. Currently used to determine if result trees are compiled using procedures or little DOMs (result tree fragments).

getValueback to summary
public boolean getValue()
toStringback to summary
public String toString()

Implements abstract com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

translateback to summary
public void translate(ClassGenerator classGen, MethodGenerator methodGen)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translate.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translate.

Translate this node into JVM bytecodes.

public void translateDesynthesized(ClassGenerator classGen, MethodGenerator methodGen)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translateDesynthesized.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translateDesynthesized.

Redefined by expressions of type boolean that use flow lists.

public Type typeCheck(SymbolTable stable) throws TypeCheckError

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.typeCheck.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.typeCheck.

Type check all the children of this node.
