TITLE

Object - Perl 6 Object class

DESCRIPTION

This file sets up the base classes and methods for Perl 6's object system. Differences (and conflicts) between Parrot's object model and the Perl 6 model means we have to do a little name and method trickery here and there, and this file takes care of much of that.

Functions

onload()

Perform initializations and create the base classes.

Object methods

Scalar()

Default implementation gives reference type semantics, and returns an object reference, unless the thing already is one.

hash()

Return a hash representation of ourself.

item()

Return the scalar component of the invocant. For most objects, this is simply the invocant itself.

list()

Return the list component of the invocant. For most (Scalar) objects, we create a List containing the invocant.

defined()

Return true if the object is defined.

Str()

Return a string representation of the object

increment

Override increment in Objects to use 'succ' method.

decrement

Override decrement in Objects to use 'pred' method.

new()

Create a new object having the same class as the invocant.

WHENCE()

Return the invocant's auto-vivification closure.

REJECTS(topic)

Define REJECTS methods for objects (this would normally be part of the Pattern role, but we put it here for now until we get roles).

true()

Defines the .true method on all objects via prefix:?.

get_bool (vtable)

Returns true if the object is defined, false otherwise.

print()

say()

Print the object

WHERE

Gets the memory address of the object.

WHICH

Gets the object's identity value

'PARROT'

Report the object's true nature.

Private methods

!cloneattr(attrlist)

Create a clone of self, also cloning the attributes given by attrlist.

Methods on P6protoobject

WHENCE()

Returns the protoobject's autovivification closure.

defined()

item()

Returns itself in item context.

list()

Returns a list containing itself in list context.

get_pmc_keyed(key) (vtable method)

Returns a proto-object with an autovivification closure attached to it.

!IMMUTABLE()

!MUTABLE()

Indicate that objects in the class are mutable or immutable.
