swfdec_as_context_startup ()

void
swfdec_as_context_startup (SwfdecAsContext *context);

Starts up the context. This function must be called before any Actionscript is called on context .

swfdec_as_context_abort ()

void
swfdec_as_context_abort (SwfdecAsContext *context,
                         const char *reason);

Aborts script execution in context . Call this functon if the script engine encountered a fatal error and cannot continue. A possible reason for this is an out-of-memory condition.

swfdec_as_context_is_aborted ()

gboolean
swfdec_as_context_is_aborted (SwfdecAsContext *context);

Determines if the given context is aborted. An aborted context is not able to execute any scripts. Aborting can happen if the script engine detects bad scripts that cause excessive memory usage, infinite loops or other problems. In that case the script engine aborts for safety reasons.

swfdec_as_context_get_string ()

const char *
swfdec_as_context_get_string (SwfdecAsContext *context,
                              const char *string);

Gets the garbage-collected version of string . You need to call this function for every not garbage-collected string that you want to use in Swfdecs script interpreter.

swfdec_as_context_give_string ()

const char *
swfdec_as_context_give_string (SwfdecAsContext *context,
                               char *string);

Takes ownership of string and returns a refcounted version of the same string. This function is the same as swfdec_as_context_get_string(), but takes ownership of string .

swfdec_as_context_use_mem ()

void
swfdec_as_context_use_mem (SwfdecAsContext *context,
                           gsize bytes);

Registers bytes additional bytes as in use by the context . This function keeps track of the memory that script code consumes. If too much memory is in use, this function may decide to stop the script engine with an out of memory error.

swfdec_as_context_try_use_mem ()

gboolean
swfdec_as_context_try_use_mem (SwfdecAsContext *context,
                               gsize bytes);

Tries to register bytes additional bytes as in use by the context . This function keeps track of the memory that script code consumes. The scripting engine won't be stopped, even if there wasn't enough memory left.

swfdec_as_context_unuse_mem ()

void
swfdec_as_context_unuse_mem (SwfdecAsContext *context,
                             gsize bytes);

Releases a number of bytes previously allocated using swfdec_as_context_use_mem(). See that function for details.

swfdec_as_context_gc ()

void
swfdec_as_context_gc (SwfdecAsContext *context);

Calls the Swfdec Gargbage collector and reclaims any unused memory. You should call this function or swfdec_as_context_maybe_gc() regularly.

swfdec_as_context_maybe_gc ()

void
swfdec_as_context_maybe_gc (SwfdecAsContext *context);

Calls the garbage collector if necessary. It's a good idea to call this function regularly instead of swfdec_as_context_gc() as it only does collect garage as needed. For example, SwfdecPlayer calls this function after every frame advancement.

swfdec_as_context_throw ()

void
swfdec_as_context_throw (SwfdecAsContext *context,
                         const SwfdecAsValue *value);

Throws a new exception in the context using the given value . This function can only be called if the context is not already throwing an exception.

swfdec_as_context_catch ()

gboolean
swfdec_as_context_catch (SwfdecAsContext *context,
                         SwfdecAsValue *value);

Removes the currently thrown exception from context and sets value to the thrown value

swfdec_as_context_get_time ()

void
swfdec_as_context_get_time (SwfdecAsContext *context,
                            GTimeVal *tv);

This function queries the time to be used inside this context. By default, this is the same as g_get_current_time(), but it may be overwriten to allow things such as slower or faster playback.

swfdec_as_context_get_frame ()

SwfdecAsFrame *
swfdec_as_context_get_frame (SwfdecAsContext *context);

This is a debugging function. It gets the topmost stack frame that is currently executing. If no function is executing, NULL is returned.

swfdec_as_context_is_constructing ()

gboolean
swfdec_as_context_is_constructing (SwfdecAsContext *context);

Determines if the contexxt is currently constructing. This information is used by various constructors to do different things when they are constructing and when they are not. The Boolean, Number and String functions for example setup the newly constructed objects when constructing but only cast the provided argument when being called.

SwfdecAsContext

typedef struct _SwfdecAsContext SwfdecAsContext;

This is the main object ued to hold the state of a script engine. All members are private and should not be accessed.

Subclassing this structure to get scripting support in your own appliation is encouraged.

The “aborted” property

  “aborted”                  gboolean

set when the script engine aborts due to an error.

Flags: Read

Default value: FALSE

The “debugger” property

  “debugger”                 SwfdecAsDebugger *

debugger used in this player.

Flags: Read / Write / Construct Only

The “memory-until-gc” property

  “memory-until-gc”          gulong

amount of bytes that need to be allocated before garbage collection triggers.

Flags: Read / Write / Construct

The “random-seed” property

  “random-seed”              guint

Default value: 0

The “trace” signal

void
user_function (SwfdecAsContext *context,
               gchar           *text,
               gpointer         user_data)

Emits a debugging string while running. The effect of calling any swfdec functions on the emitting context is undefined.

Flags: Run Last
