Class VarData

java.lang.Object

io.github.whippetdb.memory.basic.DynamicDataIO

io.github.whippetdb.memory.db.VarData

All Implemented Interfaces:

MemArray, MemBuffer, MemDataArray, MemDataBuffer, MemDataIO, MemIO

public class VarData
extends DynamicDataIO
implements MemDataBuffer

Var-length memory buffer that may created in a memspace at a certain address. Data page size may be arbitrary. Uses regular division, so it is slower than AlignedVarData.
