Method Detail

compileToItem

public String compileToItem(CompilerService compiler,
                            Expression expr)
Description copied from class: ExpressionCompiler
Generate Java code to evaluate the expression as an Item

Overrides:
compileToItem in class ToBooleanCompiler
Parameters:
compiler - the compiler service
expr - the expression to be compiled
Returns:
a simple Java expression (usually the name of a variable that has been declared) which will be of class Item, and which will hold the value of the expression at run-time (or hold null, representing an empty sequence).

compileToEffectiveBooleanValue

public String compileToEffectiveBooleanValue(CompilerService compiler,
                                             Expression expr,
                                             ReturnAction result)
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).
