Package io.fury.format.row.binary

Class BinaryMap

java.lang.Object

io.fury.format.row.binary.BinaryMap

All Implemented Interfaces:

MapData

public class BinaryMap
extends Object
implements MapData

An BinaryMap implementation of Map which is backed by two BinaryArray./FuryObjectOutput

[8 byte(key array size in bytes)] + [Key BinaryArray] + [Value BinaryArray].

Note that, user is responsible to guarantee that the key array does not have duplicated elements otherwise the behavior is undefined.
