Public Methods

Method Description
ActionTry ( ) : System

Try defines handlers for exceptional conditions, implementing the ActionScript try, catch, and finally keywords.
ActionTry ( bool storeObejct, bool finallyBlock, bool catchBlock, UInt16 trySize, UInt16 catchSize, UInt16 finallySize, string catchVarName, byte catchRegister ) : System

Try defines handlers for exceptional conditions, implementing the ActionScript try, catch, and finally keywords.
ToString ( ) : string

Converts the action to a string

Protected Methods

Method Description
Parse ( System sourceStream, byte sourceVersion ) : void

Parses try statement from a source stream. Quote from Swf spec: "The try, catch, and finally blocks do not use end tags to mark the end of their respective blocks. Instead, the length of a block is set by the TrySize, CatchSize, and FinallySize values." Additionally, see comment in ActionDefineFunction on why the code isn't read here.
ParseFrom ( ) : bool

Parses the action from a string array
Render ( System outputStream ) : ulong

Renders a try statement back to an output stream

Method Details

ActionTry() public method

Try defines handlers for exceptional conditions, implementing the ActionScript try, catch, and finally keywords.

return System

ActionTry() public method

Try defines handlers for exceptional conditions, implementing the ActionScript try, catch, and finally keywords.
public ActionTry ( bool storeObejct, bool finallyBlock, bool catchBlock, UInt16 trySize, UInt16 catchSize, UInt16 finallySize, string catchVarName, byte catchRegister ) : System
storeObejct bool False - Do not put caught object into register (instead, store in named variable) True - Put caught object into register (do not store in named variable)
finallyBlock bool True - The statement has a finally block. False The statement has no finally block
catchBlock bool True - The statement has a catch block. False The statement has no catch block
trySize System.UInt16 Length of the try block
catchSize System.UInt16 Length of the catch block
finallySize System.UInt16 Length of the finally block
catchVarName string Name of the catch variable
catchRegister byte Register to catch into
return System
