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.

existingBufferthe existing buffer from the caller.
deserializeTolocation of data.
elementCountnumber of elements.
elementSizeelement size.
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.

sizeThe number of bytes.
