Class BufferedString

java.lang.Object

water.Iced

water.parser.BufferedString

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<BufferedString>, Freezable

public class BufferedString
extends Iced
implements java.lang.Comparable<BufferedString>

A mutable wrapper to hold String as a byte array. It can be modified by set of methods, the hash code is computed on the fly. There is no speed up benefit of cashing the hash in a dedicated private field. See the speed test in ParseTest2#testSpeedOfCategoricalUpdate. Warning: This data structure is not designed for parallel access!
