Member Function Documentation

Action * ActionStoreRegister::Duplicate

(

void

)

const [private, virtual]

This function allocates a new ActionStoreRegister object, it copies the register number and returns the pointer of the new action.

Returns:

The action clone pointer

Reimplemented from sswf::Action.

int ActionStoreRegister::GetMaxRegister

(

void

)

const [private, virtual]

This function gets the larger register number in use by this action. This is actually equal to the register you defined with SetRegister() or zero.

Returns:

The largest register number in use by this action

Reimplemented from sswf::Action.

ErrorManager::error_code_t ActionStoreRegister::SaveData	(	Data &	data,
		Data &	nested_data
	)			[private, virtual]

This means saving one byte with the register number.

Parameters:

[in]	data	The Data buffer where the register number is to be saved
[in]	nested_data	The ActionStoreRegister does not support nested data

Reimplemented from sswf::Action.

void ActionStoreRegister::SetRegister

(

unsigned char

reg

)

This function can be used to define the register number to hold the current stack content.

Outside a function, only registers 0 to 3 are acceptable.

Inside a function (DeclareFunction2--Version 7 of SWF), all registers from 0 to 254 are acceptable. (from my testing it seems that register 255 does not work.)

Parameters:

[in]

reg

The new register to assign to this action
