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

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

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

Parameters
value:String

the attribute value.

Method Detail

contextDependentback to summary
protected 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).

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.

Translate this attribute value into JVM bytecodes that pushes the attribute value onto the JVM's stack.

Parameters
classGen:ClassGenerator

BCEL Java class generator

methodGen:MethodGenerator

BCEL Java method generator

typeCheckback to summary
public Type typeCheck(SymbolTable stable) throws TypeCheckError

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

Returns this attribute value's type (String).

Parameters
stable:SymbolTable

The compiler/parser's symbol table
