NAME

object.ops - Class and Object Opcodes

DESCRIPTION

Parrot's library of object ops

When making changes to any ops file, run make bootstrap-ops to regenerate all generated ops files.

callmethodcc(invar PMC, in STR)

Call method $2 with invocant $1 and generate a new return continuation. The invocant ($1) is used for method lookup. The object is passed as the first argument in set_args.Throws a Method_Not_Found_Exception for a non-existent method.

callmethodcc(invar PMC, invar PMC)

Like above but use the Sub object $2 as method.

callmethod(invar PMC, in STR, invar PMC)

callmethod(invar PMC, invar PMC, invar PMC)

Like above, but use continuation $3 instead of creating a new continuation.

tailcallmethod(invar PMC, in STR)

tailcallmethod(invar PMC, invar PMC)

Make a tailcall to method $2 with invocant $1.

addmethod(invar PMC, in STR, invar PMC)

Adds $3 as a method named $2 to $1.

can(out INT, invar PMC, in STR)

Sets result $1 to the result of the "can" vtable function for PMC $2, given method $3.

does(out INT, invar PMC, in STR)

Sets result $1 to the result of the "does" vtable function for PMC $2, given the role of name $3.

does(out INT, invar PMC, in PMC)

Sets result $1 to the result of the "does" vtable function for PMC $2, given the role $3.

isa(out INT, invar PMC, in STR)

isa(out INT, invar PMC, in PMC)

Sets result $1 to the result of the "isa" vtable function for PMC $2, given class $3.

newclass(out PMC, in STR)

Create a new Parrot-style class, named $2, and puts the new PMC for it into $1.

newclass(out PMC, in PMC)

Create a new Parrot-style class, with the name given in $2 as a key, namespace, or string PMC.

subclass(out PMC, in PMC)

subclass(out PMC, in PMC, in STR)

subclass(out PMC, in PMC, in PMC)

Create a new class, put in $1, that is a subclass of $2. $3, if available and not null, is the name of the new class--if not, the subclass is an anonymous subclass.

subclass(out PMC, in STR)

subclass(out PMC, in STR, in STR)

subclass(out PMC, in STR, in PMC)

Create a new class, put in $1, that is a subclass of the class named $2. $3, if available and not null, is the name of the new class--if not, the subclass is an anonymous subclass.

get_class(out PMC, in STR)

get_class(out PMC, in PMC)

Find the PMC for a class, by string name, key or namespace. This op does not find the class of an instance of an object. use typeof for that.

class(out PMC, invar PMC)

Get the class PMC for the object in $2 and put it in $1.

addparent(invar PMC, invar PMC)

Add class $2 to the list of parent classes for $1.

removeparent(invar PMC, invar PMC)

Remove class $2 from class $1's list of parents.

addrole(invar PMC, invar PMC)

Compose the role $2 into $1.

addattribute(invar PMC, in STR)

Add the attribute named $2 to the class $1.

removeattribute(invar PMC, in STR) (unimplemented)

Remove attribute $2 from class $1, specified by name.

getattribute(out PMC, invar PMC, in STR)

Get the attribute $3 from object $2 and put the result in $1.

getattribute(out PMC, invar PMC, in PMC, in STR)

Get the attribute $4 from the parent $3 of object $2 and put the result in $1. (This is useful for storing data for a parent class attribute that is overridden in a child class.) The parent $3 is a class name, namespace, or key PMC.

setattribute(invar PMC, in STR, invar PMC)

Set attribute $2 of object $1 to $3.

setattribute(invar PMC, in PMC, in STR, invar PMC)

Set attribute $3 of the parent $2 of object $1 to $4. (This is useful for storing data for a parent class attribute that is overridden in a child class.) The parent $2 is a class name, namespace, or key PMC.

inspect(out PMC, in PMC)

Sets $1 to a PMC hash of all introspection data available for $2, keyed on name.

inspect(out PMC, in PMC, in STR)

Sets $1 to a PMC Hash, Array, String, Integer, or Number value with introspection information corresponding to the requested string name.
