Class HexishString

java.lang.Object

hudson.plugins.findbugs.parser.HexishString

All Implemented Interfaces:

Serializable

public final class HexishString
extends Object
implements Serializable

Efficient representation for mostly hexadecimal strings. If the string is "([0-9a-f][0-9a-f])*", this class internally uses byte[] to represent the string in the most compact form. At the same time, the class is designed not to lose any information in the original string, so if the input does not fit this pattern, original string is retained. In the test data, I noted some small number of hex strings that are 31 letter long, and in any case assuming that the instance hash is hex string is a dangerous assumption anyway.

In either case, new HexishString(x).toString().equals(x) for any non-null string.

This class is developed to represent "instance hash" that findbugs produces, which appears to be 128bit information encoded in the hex form. In String with associated char[], it takes up about 128 bytes, but in this form it only occupies about 64 bytes if it's hex, and 112 when it's not. So it's more space efficient either way.
