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 does does_pmc elements exists_keyed exists_keyed_int exists_keyed_str find_method freeze 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 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 get_string_keyed_srt getprop Get the value of a certain property from 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 its children as alive for the memory manager. This prevents children of the PMC from being collected prematurely by the garbage collector. morph name neg new_from_string nextkey_keyed nextkey_keyed_int nextkey_keyed_str pop_float If the PMC is an array, pops a floating point value off the top of it pop_integer If the PMC is an array, pops an integer value off the top of it pop_pmc If the PMC is an array, pops a PMC value off the top of it pop_string If the PMC is an array, pops a string value off the top of it push_float If the PMC is an array, pushes a floating point value onto the top of it push_integer If the PMC is an array, pushes an integer onto the top of it push_pmc If the PMC is an array, pushes a PMC onto the top of it push_string If the PMC is an array, pushes a string onto the top of it remove_attribute Removes an attribute from the PMC remove_method remove_parent remove_role remove_vtable_override set_attr Sets an attribute value for the given PMC set_attr_keyed set_attr_keyed_str set_bugnum_int set_bignum_num set_bignum_str set_bool Sets the value of the PMC as if it were a boolean set_integer_keyed set_integer_keyed_int set_integer_keyed_str set_integer_native Sets the value of the PMC as if it were an integer set_number_keyed set_number_keyed_int set_number_keyed_str set_number_native Sets the value of the PMC as if it were a floating point value set_number_same set_pmc Sets the value of a PMC to the value of another PMC set_pmc_keyed set_pmc_keyed_int set_pmc_keyed_str set_pointer set_pointer_keyed set_pointer_keyed_int set_pointer_keyed_str set_string_keyed set_string_keyed_int set_string_keyed_str set_string_native Sets the value of the PMC as if it were a string set_string_same setprop share share_ro shift_float If the PMC is an array, shifts a floating point value onto the bottom of it shift_int If the PMC is an array, shifts an integer onto the bottom of it shift_pmc If the PMC is an array, shifts a PMC onto the bottom of it shift_string If the PMC is an array, shifts a string onto the bottom of it slice splice substr substr_str thaw thawfinish type type_keyed type_keyed_int type_keyed_str unshift_float If the PMC is an array, unshifts a floating point valuefrom the bottom of it unshift_integer If the PMC is an array, unshifts an integer from the bottom of it unshift_pmc If the PMC is an array, unshifts a PMC from the bottom of it unshift_str If the PMC is an array, unshifts a string from the bottom of it visit
