Interface PrimitiveIdTypeOps<T>

Type Parameters:

T - Type

All Superinterfaces:

PrimitiveTypeOps<T>, TypeOps<T>

All Known Implementing Classes:

IntTypeOps, LongTypeOps

public interface PrimitiveIdTypeOps<T>
extends PrimitiveTypeOps<T>

Additional type operations to TypeOps for types that can be IDs, and so can be used as keys in maps and values in sets. Using any of the provided operations should lead to no boxing/unboxing. Useful generic wrappers to fastutil libraries are provided, so that you can look at them generically.

Method Detail

createOpenHashSet

BasicSet<T> createOpenHashSet()

Create BasicSet of type T.

Returns:

BasicSet

createOpenHashSet

BasicSet<T> createOpenHashSet(long capacity)

Create BasicSet of type T, given capacity.

Parameters:

capacity - Capacity

Returns:

BasicSet

create2ObjectOpenHashMap

<V> Basic2ObjectMap<T,V> create2ObjectOpenHashMap(WritableWriter<V> valueWriter)

Create Basic2ObjectMap with key type T. Values are represented as object, even if they can be primitive. You can pass null as valueWriter, but readFields/write will throw an Exception, if called.

Type Parameters:

V - Type of values in the map

Parameters:

valueWriter - Writer of values

Returns:

Basic2ObjectMap

create2ObjectOpenHashMap

<V> Basic2ObjectMap<T,V> create2ObjectOpenHashMap(int capacity,
                                                  WritableWriter<V> valueWriter)

Create Basic2ObjectMap with key type T, given capacity. Values are represented as object, even if they can be primitive. You can pass null as valueWriter, but readFields/write will throw an Exception, if called.

Type Parameters:

V - Type of values in the map

Parameters:

capacity - Capacity

valueWriter - Writer of values

Returns:

Basic2ObjectMap
