Detailed Description

Provides information about timeline context.

This class stores information about the current and original "target" of execution. A target is a MovieClip or other AS-referenceable DisplayObject. Non-timeline code has no target. Why should a timeline context provide access to the VM stack? It shouldn't! TODO: remove stack access proxy functions, SWF version, etc.

Member Function Documentation

drop()

void gnash::as_environment::drop ( size_t  count )

inline

Drop 'count' values off the top of the stack.

get_original_target()

DisplayObject* gnash::as_environment::get_original_target ( ) const

inline

Referenced by gnash::Function2::call(), gnash::findObject(), gnash::ActionExec::getThisPointer(), and gnash::parsePath().

get_version()

int gnash::as_environment::get_version

(

)

const

Return the SWF version we're running for.

This is merely a proxy for VM::getSWFVersion.

markReachableResources()

void gnash::as_environment::markReachableResources

(

)

const

Mark all reachable resources.

Only the targets are reachable.

References gnash::GcResource::setReachable().

Referenced by gnash::MovieClip::markOwnResources(), and stack_size().

pop()

as_value gnash::as_environment::pop ( )

inline

Pops an as_value off the stack top and return it.

Referenced by gnash::SWF::SWFHandlers::execute(), and gnash::ActionExec::operator()().

push()

void gnash::as_environment::push ( const as_value &  val )

inline

Push a value on the stack.

Referenced by gnash::ActionExec::operator()().

reset_target()

void gnash::as_environment::reset_target ( )

inline

set_original_target()

void gnash::as_environment::set_original_target ( DisplayObject *  target )

inline

References target().

Referenced by gnash::TargetGuard::TargetGuard(), and gnash::TargetGuard::~TargetGuard().

set_target()

void gnash::as_environment::set_target ( DisplayObject *  target )

inline

Set default target for timeline opcodes.

Parameters

target

A DisplayObject to apply timeline opcodes on. Zero is a valid target, disabling timeline opcodes (would get ignored).

References target().

Referenced by gnash::MovieClip::MovieClip(), gnash::ActionExec::operator()(), gnash::TargetGuard::TargetGuard(), and gnash::TargetGuard::~TargetGuard().

stack_size()

size_t gnash::as_environment::stack_size ( ) const

References gnash::delVariable(), DSOEXPORT, gnash::findObject(), gnash::findTarget(), get_version(), gnash::getVariable(), markReachableResources(), gnash::parsePath(), path, and gnash::setVariable().

Referenced by gnash::ActionExec::operator()().

target()

DisplayObject* gnash::as_environment::target ( ) const

inline

top()

as_value& gnash::as_environment::top ( size_t  dist ) const

inline

Get stack value at the given distance from top.

top(0) is actual stack top

Throw StackException if index is out of range
