Detailed Description

Base class for all Zerobuf serializable objects.

The zerobufCxx.py code generator creates subclasses of this class. Zerobuf objects can serialize/deserialize directly from their member storage and from and to JSON. All members are zero-initialized, unless they do have a default value. fromJSON() will compact the Zerobuf.

Member Function Documentation

virtual void zerobuf::Zerobuf::compact ( float  threshold = 0.1f )

virtual

Remove unused holes from the zerobuf.

Compaction only occurs if the current allocation exceeds the relative threshold to the optimal size, that is, if unusedMemory divided by optimalMemory is above the threshold.

Parameters

threshold

the compaction threshold

Reimplemented in zerobuf::render::ImageJPEG.

Referenced by notifyChanging().

Returns

the number of dynamics fields of this object.

Implemented in zerobuf::render::Camera, zerobuf::render::ImageJPEG, zerobuf::render::Vector3f, and zerobuf::render::LookupTable1D.

virtual size_t zerobuf::Zerobuf::getZerobufStaticSize ( ) const

pure virtual

Returns

the static size of this object in bytes.

Implemented in zerobuf::render::Camera, zerobuf::render::ImageJPEG, zerobuf::render::Vector3f, and zerobuf::render::LookupTable1D.
