Method Detail

compileToItem

public String compileToItem(CompilerService compiler,
                            Expression exp)

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

exp - 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).
