Examples of WaveletOperation

org.waveprotocol.wave.model.operation.wave.WaveletOperation
Superclass of all wavelet operations. A wavelet operation occurs in a {@link WaveletOperationContext}, and applies to a {@link WaveletData}. wavelet operations are also {@link Visitable} for the purpose of extracting serializationand merge logic into separate classes. Operations are partitioned into wavelet operations, blip operations, and document operations, in order to reduce the number of operation pairs that must be considered for transform and merge (it only makes sense to transform or merge operations that apply to the same type). The boxing relationships where document ops are boxed as a blip operation, which in turn is boxed as a wavelet operation, are as follows: Operation A ____________________________________|______________________________________ | | | WaveletOperation --- BlipOperation --- DocumentOperation A | A | A ____|__________ | ____|___________ | ______|______ | | | | | | | | | | ... ... WaveletBlipOperation <>-- ... ... BlipContentOperation <>-- ... (XML ops) ...
