Method Detail

getMethodCount

public int getMethodCount()

getMethod

public MethodProc getMethod(int i)

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

addAll

protected void addAll(MethodProc[] procs)

addAtEnd

public void addAtEnd(MethodProc method)

add

public void add(MethodProc method)

isApplicable

public int isApplicable(Type[] args,
                        Type restType)

Description copied from class: MethodProc

Test if method is applicable to an invocation with given arguments.

Overrides:

isApplicable in class MethodProc

Parameters:

args - array of known "single" arguments.

restType - If null, the arguments are fully specified by argTypes. If non-null, there may be an unknown number of extra arguments of the given restType. This is used for splices, where we usually don't know at compile-time how many argument values we have.

Returns:

-1 if no; 1 if yes; 0 if need to check at run-time.

applyToConsumerGP

public static java.lang.Object applyToConsumerGP(Procedure proc,
                                                 CallContext ctx)
                                          throws java.lang.Throwable

Throws:

java.lang.Throwable

setProperty

public void setProperty(Keyword key,
                        java.lang.Object value)

setProperties

public final void setProperties(java.lang.Object[] args)

make

public static GenericProc make(java.lang.Object[] args)

Create a GenericProc from one or more methods, plus properties.

makeWithoutSorting

public static GenericProc makeWithoutSorting(java.lang.Object... args)
