NAME
src/pmc/packfileconstanttable.pmc - PackfileConstantTable PMC
DESCRIPTION
This class implements a PackfileConstantTable object, a segment of the .pbc data file used for storing constants of various types. (int, string, PMC)
See packfile.pmc for the toplevel Packfile interface, see packfilesegment.pmc for the list of common methods every packfile segment pmc must implement; see PDD13 for the design spec.
Methods
init
Create empty PackfileConstantTable.
void mark()
Marks the object as live.
void destroy()
Destroys the PMC and frees all allocated memory.
set_pointer
Set pointer to underlying PackFile_ConstTable
void *get_pointer()INTVAL elements()
Get the number of elements in the array.
FLOATVAL get_number_keyed_int(INTVAL index)
Fetch a numeric constant.
An exception is thrown if the given constant isn't numeric.
STRING *get_string_keyed_int(INTVAL index)
Fetch a string constant.
An exception is thrown if the given constant isn't a string.
PMC *get_pmc_keyed_int(INTVAL index)
Fetch a PMC constant.
An exception is thrown if the given constant isn't a PMC.
void set_number_keyed_int(INTVAL index, FLOATVAL value)
Set the constant to the given number.
void set_string_keyed_int(INTVAL index, STRING *value)
Set the constant to the given string.
void set_pmc_keyed_int(INTVAL index, PMC *value)
Set the constant to the given PMC (or key).
INTVAL get_type(INTVAL index)
Get the type of the specified constant.
