Detailed Description

Callback class for deserialization.

This must be provided by code that calls deserialize.

Member Function Documentation

virtual std::tr1::shared_ptr<const Field> epics::pvData::DeserializableControl::cachedDeserialize ( ByteBuffer *  buffer )

pure virtual

deserialize via cache

Parameters

buffer

buffer to be deserialized from

virtual bool epics::pvData::DeserializableControl::directDeserialize ( ByteBuffer *  existingBuffer, char *  deserializeTo, std::size_t  elementCount, std::size_t  elementSize  )

pure virtual

Method for deserializing array data. Hook for supplying custom deserialization implementation. The deserialization implementation need not be provided. Returns true if method performs deserialization, false otherwise. This should only be used for arrays of primitive types. i.e. boolean, byte,..., double. It cannot be called for string, structure, or union arrays.

Parameters

existingBuffer	the existing buffer from the caller.
deserializeTo	location of data.
elementCount	number of elements.
elementSize	element size.

Returns

true if deserialization performed, else false.

virtual void epics::pvData::DeserializableControl::ensureData ( std::size_t  size )

pure virtual

Helper method. Ensures specified size of bytes, provides it if necessary.

Parameters

size	The number of bytes.
