Class FloatParser

java.lang.Object

prefuse.data.parser.FloatParser

All Implemented Interfaces:

DataParser

public class FloatParser
extends java.lang.Object
implements DataParser

DataParser instance that parses float values from a text string. Float values can be explicitly coded for by using a 'f' at the end of a number. For example "1.0" could parse as a double or a float, but "1.0f" will only parse as a float.
