All Implemented Interfaces:

Inlineable, Named

public class ValuesMap
extends MethodProc
implements Inlineable

Map a function over a value sequence, yielding a new sequence. Normally, the function takes one argument, the item in the sequence. If startCounter is non-negative, a position index is also passed. Used to implement XQuery's 'for' form.

Method Details

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.

Overrides:

numArgs in class Procedure

compile

public void compile(ApplyExp exp,
 Compilation comp,
 Target target)

Specified by:

compile in interface Inlineable

compileInlined

public static void compileInlined(LambdaExp lambda,
 Expression vals,
 int startCounter,
 Method matchesMethod,
 Compilation comp,
 Target target)

getReturnType

public Type getReturnType(Expression[] args)

Description copied from class: Procedure

Semi-deprecated - instead should be set at Inline time. FIXME

Overrides:
