Method Detail

wrapValueBytesAsData

public Data<V> wrapValueBytesAsData(net.openhft.chronicle.bytes.BytesStore<?,?> bytesStore,
                                    long offset,
                                    long size)

Description copied from interface: MapContext

Wraps the given value bytes as a Data. Useful when you need to pass a value to some method accepting Data, for example, MapEntryOperations.replaceValue( MapEntry, Data), without allocating manual deserialization and ThreadLocals.

The returned Data object shouldn't outlive this MapContext.

Specified by:

wrapValueBytesAsData in interface MapContext<K,V,R>

Parameters:

bytesStore - the value bytes to wrap

offset - offset within the given valueBytes, the actual value bytes start from

size - length of the value bytes sequence

Returns:

the value bytes as Data
