compileToEffectiveBooleanValue

public java.lang.String compileToEffectiveBooleanValue(CompilerService compiler,
                                                       Expression expr,

Description copied from class: ExpressionCompiler

Generate Java code to evaluate the effective boolean value of the expression

Specified by:

compileToEffectiveBooleanValue in class ToBooleanCompiler

Parameters:

compiler - the compiler service

expr - the XPath expression to be compiled

result - indicates how the boolean result is to be returned

Returns:

the result depends on the supplied value of the options argument. If options is a JavaDeclaration, the code must declare a Java variable and return the name of this variable. If options is a JavaAssignment, the code must assign the value to an existing Java variable. If options is a Return, the code must generate a return statement that returns the value of the boolean (in which case the result of this method is null).
