Member Function Documentation

getID()

virtual const ID<Proc>& getID ( ) const

inlinevirtual

<

Returns

ID of kind Proc

Reimplemented from Asset.

Definition at line 77 of file proc.hpp.

resolveProcessor()

virtual ProcFunc* resolveProcessor ( ) const

pure virtual

resolve any plugin and configuration info to yield the actual media data processing function.

Returns

a function ready to be invoked; either the "real thing" or a suitable placeholder.

Exceptions

lumiera::error::Fatal

if unable to provide any usable function or placeholder. This case can be considered exceptional and justifies a subsystem failure.

Implemented in Effect.
