java.lang.Object

org.kepler.objectmanager.data.text.TextComplexFormatDataReader

public class TextComplexFormatDataReader
extends java.lang.Object

Author:

tao This class will read a data inputstream and split them into a row vectors base on the given ComplexDataFormat array. This class have a public method - getRowVector.After reach the end of stream, empty vector will be returned. So this method can be iterated by a while loop until a empty vector hited. During the iteration, every data in the stream will be pulled out.
