Constructor Detail

LiteralExpr

public LiteralExpr(java.lang.String value)

Creates a new literal expression node.

Parameters:

value - the literal expression content/value.

LiteralExpr

public LiteralExpr(java.lang.String value,
                   java.lang.String namespace)

Creates a new literal expression node.

Parameters:

value - the literal expression content/value.

namespace - the namespace in which the expression exists.

Method Detail

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError

Description copied from class: Expression

Type check all the children of this node.

Overrides:

typeCheck in class Expression

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

toString

public java.lang.String toString()

Specified by:

toString in class Expression

contextDependent

protected boolean contextDependent()

Description copied from class: SyntaxTreeNode

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).

Overrides:

contextDependent in class SyntaxTreeNode

Returns:

'true' if this node depends on the context.

getValue

protected java.lang.String getValue()

getNamespace

protected java.lang.String getNamespace()

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)

Description copied from class: Expression

Translate this node into JVM bytecodes.

Overrides:

translate in class Expression

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator
