Detailed Description

The processor manager.

This class centralizes the processing of all types of results. It maps Processor's names to a corresponding pointer to Processor.

Given the Processor's name and an input sufficient for the processing, this class redirects the input to the correct Processor.

This class is a singleton that is constructed only when its getInstance() method is called for the first time.

Member Data Documentation

const Processor* kvProcessors_[] [static, private]

An array of registers of KeyValue Processor implementations is needed to have at least one symbol in KeyValue library which refer to the registers. Otherwise they won't be included by the linker and, consequently, registration won't occur.

This variable is set in keyvalue/mngt/Register.cpp

const Processor* processors_[] [static, private]

Similarly to kvProcessors_ but for Processors of core library objects and results.

This variable must be set by the bridge library.
