Parrot Virtual Machine/VTABLE List

Vtable List

Vtable name	Description
absolute	Returns the absolute value of the PMC, as a PMC
add_attribute	Adds an attribute to the PMC object. Attributes are typically stored in the pmc->pmc_ext->_metadata field.
add_method	Adds a new method to the PMC's class
add_parent
add_role
add_vtable_override
assign_pmc	Assigns a PMC value to the PMC
assign_string_native	Assigns a string to the PMC
bitwise_not
bitwise_nots
can
clone
clone_pmc
decrement	Decrements the integer value of the PMC by 1
defined	Determines if the PMC is defined
defined_keyed
defined_keyed_int
defined_keyed_str
delprop	Deletes a property from the PMC
destroy	Destroy the PMC

get_attr
get_bignum	Gets the BigNum representation of the PMC
get_bool	Gets the boolean representation of the PMC
get_class
get_integer	Gets the integer representation of the PMC
get_integer_keyed
get_integer_keyed_int
get_integer_keyed_str
get_iter
get_namespace
get_number	Gets the floating-point representation of the PMC
get_number_keyed
get_number_keyed_int
get_number_keyed_str
get_pmc	Gets the PMC representation of the PMC
get_pmc_keyed
get_pmc_keyed_int
get_pmc_keyed_str
get_pointer

get_pointer_keyed_int
get_pointer_keyed_str
get_repr
get_string	Gets the string representation of the PMC
get_string_keyed
get_string_keyed_int

getprops
i_absolute
i_bitwise_not
i_bitwise_nots
i_logical_not
i_net
increment	Increments the integer value of the PMC by 1
init	Initializes the PMC. This method is called when the new keyword is used to create a new PMC.
init_pmc
inspect
inspect_str
instantiate
invoke	The invoke vtable method is called when the PMC is called like a function. In the following code: .local pmc mypmc = new 'MyPMCType' mypmc() The invoke vtable method is called on the second line when the PMC is treated as a function call. For string functions, for example, the string class uses the value of the string to look up a function with the same name, and then invokes that function. Subroutine PMCs invoke the given function when they are called.
is_same
isa
isa_pmc
logical_not
mark	Mark the PMC and all its children as alive for the memory manager. This prevents children of the PMC from being collected prematurely by the garbage collector.
