## Detailed Description

## Constructor & Destructor Documentation

AlpsKnowledgeBroker::AlpsKnowledgeBroker | ( | const AlpsKnowledgeBroker & |  | ) | `[private]`

AlpsKnowledgeBroker::AlpsKnowledgeBroker | ( |  | ) |

Default constructor.

virtual AlpsKnowledgeBroker::~AlpsKnowledgeBroker | ( |  | ) | `[virtual]`

Destructor.

## Member Function Documentation

AlpsKnowledgeBroker& AlpsKnowledgeBroker::operator= | ( | const AlpsKnowledgeBroker & |  | ) | `[private]`

void AlpsKnowledgeBroker::registerClass | ( | int | name,
|  | AlpsKnowledge * | userKnowledge |
| ) |  |  | `[inline]`

Every user derived knowledge class must register.

The register methods register the decode method of the class so that later on we can decode objects from buffers. Invoking this registration for class `foo` is a single line:
`foo().registerClass(name, userKnowledge)`. NOTE: take over user knowledge's memory ownership, user doesn't need free memory.

Definition at line 230 of file AlpsKnowledgeBroker.h.

References decodeMap_.

const AlpsKnowledge* AlpsKnowledgeBroker::decoderObject | ( | int | name | ) | `[inline]`

This method returns the pointer to an empty object of the registered class `name`.

Then the `decode()` method of that object can be used to decode a new object of the same type from the buffer. This method will be invoked as follows to decode an object whose type is `name`:
`obj = AlpsKnowledge::decoderObject(name)->decode(buf)`
