LiteralExprback to summary
public LiteralExpr(String value)

Creates a new literal expression node.

Parameters
value:String

the literal expression content/value.

Creates a new literal expression node.

Parameters
value:String

the literal expression content/value.

namespace:String

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).

getNamespaceback to summary
protected String getNamespace()

protected String 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.

typeCheckback to summary
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.
