When you access an ActionScript class object or primitive data
type variable from your native C implementation, you use an FREObject
variable. The runtime associates an FREObject variable with the
corresponding ActionScript object.
FREObject variables are used in native functions you implement
with the signature
FREFunction()
. The native functions:
Receive FREObject variables as parameters.
Return an FREObject variable.
FREObject variables are also used when you use native extensions
C API functions to:
Create an ActionScript class object or ActionScript
primitive data type.
Get the value of an ActionScript class object or ActionScript
primitive data type.
Create an ActionScript String object.
Get the value of an ActionScript String object.
Get or set a property of an ActionScript object.
Call a method of an ActionScript object.
Access the bits of an ActionScript BitmapData object.
Access the bytes of an ActionScript ByteArray object.
Get or set the length of an ActionScript Array or Vector
object.
Get or set an element of an ActionScript Array or Vector
object.
Get an ActionScript Error object when the runtime throws
an exception in a native extension C API function call.
Set or get an ActionScript object in the ActionScript context
data.
