Method Detail

getData

public int getData(double[] target,
                   int targetPos,
                   int length)

Try to get length doubles from this DoubleDataSource, and copy them into target, starting from targetPos. This is the core method getting the data. Subclasses may want to override this method. If an exception occurs reading from the underlying reader, or converting data to double, the method will print a stack trace to standard error, but otherwise will silently stop and behave as if all data was read.

Specified by:

getData in interface DoubleDataSource

Overrides:

getData in class TextReaderDoubleDataSource

Parameters:

target - the double array to write into

targetPos - position in target where to start writing

length - the amount of data requested

Returns:

the amount of data actually delivered. If the returned value is less than length, only that many data items have been copied into target; further calls will return 0 and not copy anything.
