apply2

public java.lang.Object apply2(java.lang.Object arg0,
                               java.lang.Object arg1)

Create a method or generic of the matching methods.

Specified by:

apply2 in class Procedure2

Parameters:

arg0 - a Class, ClassType, or a CharSequence or Symbol that names a class.

arg1 - a method name (a CharSequence, or Symbol) Loosely the same as GetNamedPart.make(arg0, arg1), but with some extra conversions and checks.

apply

public static MethodProc apply(Procedure thisProc,
                               java.lang.Object arg0,
                               java.lang.Object arg1)

getMethods

public static PrimProcedure[] getMethods(ObjectType dtype,
                                         java.lang.String mname,
                                         char mode,
                                         ClassType caller,
                                         Language language)

Return the methods of a class with the specified name and flag.

Parameters:

caller - if non-null, check that methods are accessible in it.

Returns:

an array containing the methods.

selectApplicable

public static long selectApplicable(PrimProcedure[] methods,
                                    Type[] atypes,
                                    Type restType)

Re-order the methods such that the ones that are definite applicable (all argtypes is subset of parameter type) are first; those possibly applicable next (argtype overlaps parameter types); and ending with those definitely not applicable (some argtype does overlap its parameter type).

Returns:

((number of definitely applicable methods) << 32 + (number of possibly applicable methods.

selectApplicable

public static int selectApplicable(PrimProcedure[] methods,
                                   int numArgs,
                                   boolean maybeMore)

Select methods that have the right number of parameters.

Returns:

number of methods that apply, NO_MATCH_TOO_FEW_ARGS, or NO_MATCH_TOO_MANY_ARGS.

apply

public static MethodProc apply(ObjectType dtype,
                               java.lang.String mname,
                               char mode,
                               Language language)

Find methods.

Parameters:

dtype - class to search

mname - method name (already mangled, if need be).

mode - one of 'P' (use invokespecial). 'V' (require this argument even if method is static), or '\0' (otherwise).
