Vtable List[edit]

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

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 it's children as alive for the memory manager. This prevents children of the PMC from being collected prematurely by the garbage collector.
