Method Detail

compileToEffectiveBooleanValue

public String compileToEffectiveBooleanValue(CompilerService compiler,
                                             Value expr,
                                             ReturnAction options)

Overrides:

compileToEffectiveBooleanValue in class ValueCompiler

compileToCharSequence

public String compileToCharSequence(CompilerService compiler,
                                    AtomicValue exp)

Compile Java code whose effect is to compute the string value of the expression; the generated code returns a CharSequence. This method must only be called for an expression that is known to return a value of type xs:string

Overrides:

compileToCharSequence in class ValueCompiler

Parameters:

exp - The expression to be compiled

Returns:

the name of a variable to which the resulting CharSequence is assigned, or a Java expression that can be used in a place where a variable reference of type CharSequence is allowed.

toJavaExpression

public String toJavaExpression(AtomicValue value,
                               CompilerService compiler)

Specified by:

toJavaExpression in class ValueCompiler
