Class FactoryFlatBuffers<T,S extends Geometry>

java.lang.Object

com.github.davidmoten.rtree.fbs.FactoryFlatBuffers<T,S>

Type Parameters:

T - the object type

S - the geometry type

All Implemented Interfaces:

EntryFactory<T,S>, Factory<T,S>, LeafFactory<T,S>, NonLeafFactory<T,S>

public final class FactoryFlatBuffers<T,S extends Geometry>
extends Object
implements Factory<T,S>

Conserves memory in comparison to FactoryDefault especially for larger maxChildren by saving Leaf objects to byte arrays and using FlatBuffers to access the byte array.
