NAME

src/pmc/callcontext.pmc - CallContext PMC

DESCRIPTION

The CallContext PMC is used to store the argument list and argument meta information for a multiple dispatch call.

Functions

void init()

Initializes a newly created CallContext object.

void mark()

Mark any referenced strings and PMCs.

void morph(PMC *type)

Morph the call signature into a return signature. (Currenly ignores the type passed in, and resets the named and positional arguments stored.)

void set_string_native(STRING *value)

Sets the short signature for the CallContext.

STRING *get_string()

Returns the short signature for the CallContext.

void set_pmc(PMC *value)

Sets a fixed-size array of integer types (a type tuple) for the CallContext.

PMC *get_pmc()

Returns a fixed-size array of integer types (a type tuple) for the CallContext.

void set_attr_str(STRING *key, PMC *value)

Set a PMC value for an attribute by string name.

results

Stores the return signature, an array of PMCs.

arg_flags

Stores a set of flags for the call signature arguments, an array of integers.

return_flags

Stores a set of flags for the call signature return arguments, an array of integers.

PMC *get_attr_str(STRING *key)

Get a PMC value for an attribute by string name.

results

Retrieves the return signature, an array of PMCs.

arg_flags

Retrieves the flags for the call signature arguments, an array of integers.

return_flags

Retrieves the flags for the call signature return arguments, an array of integers.

named

Retrieves the hash of named arguments.

caller_ctx

return Caller Context

lex_pad

return LexPad

outer_ctx

return Outer Context

current_sub

return current Sub

handlers

return list of ExceptioHandlers

current_cont

return current Continuation

current_object

return current Object (if in method call)

current_namespace

return current Namespace

PMC *clone()

Creates and returns a clone of the signature.

PMC *backtrace

Gets a representation of the backtrace starting from this Context. Returns an array of hashes. Each array element represents a caller in the backtrace, the most recent caller first. The hash has two keys: sub, which holds the PMC representing the sub, and annotations which is a hash of the annotations at the point where the exception was thrown for the current sub, or for the point of the call a level deeper for the rest.
