public interface TransformationStrategy<T>
extends Serializable

A generic transformation from objects of a given type to bit vector. Most useful when adding strings, etc. to a trie.

Method Summary

TransformationStrategy<T>	copy() Returns a copy of this transformation strategy.
long	numBits() The (approximate) number of bits occupied by this transformation.
BitVector	toBitVector(T object) Returns a bit vector representation of the given object.

Method Detail

toBitVector

BitVector toBitVector(T object)

Parameters:

object - the object to be turned into bit representation.

Returns:

a bit vector representation of object.

numBits

long numBits()

The (approximate) number of bits occupied by this transformation.

Returns:

the (approximate) number of bits occupied by this transformation.

copy

TransformationStrategy<T> copy()

Returns a copy of this transformation strategy.

Returns:

a copy of this transformation strategy.
