Method Detail

compileToIterator

public String compileToIterator(CompilerService compiler,
                                Expression expr)

Description copied from class: ExpressionCompiler

Generate Java code to evaluate the expression as a SequenceIterator

Specified by:

compileToIterator in class ExpressionCompiler

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 SequenceIterator, and which at run-time will hold an iterator over the the value of the expression

compileAsLoop

public void compileAsLoop(CompilerService compiler,
                          Expression expr,
                          LoopAction action)

Compile an expression in the form of a loop. Default implementation.

Overrides:

compileAsLoop in class ExpressionCompiler

Parameters:

compiler - the CompilerService

expr - the expression to be compiled

action - the action to be taken to process each item in the sequence returned by the expression

compileAsCharSequenceLoop

public static void compileAsCharSequenceLoop(CompilerService compiler,
                                             AtomicSequenceConverter exp,
                                             LoopAction action)

Special method to compile as a sequence of unboxed CharSequence objects. Must only be called if the required type is xs:string

Parameters:

compiler -

exp -

action -
