Method Detail

hasMoreData

public boolean hasMoreData()

Description copied from class: BufferedDoubleDataSource

Whether or not any more data can be read from this data source.

Specified by:

hasMoreData in interface DoubleDataSource

Overrides:

hasMoreData in class BufferedDoubleDataSource

Returns:

true if another call to getData() will return data, false otherwise.

getData

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

This implementation of getData() will cut off a tail corresponding to half of the FIR filter.

Specified by:

getData in interface DoubleDataSource

Overrides:

getData in class BufferedDoubleDataSource

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.

readBlock

protected int readBlock(double[] target,
            int targetPos)

Try to get a block of getBlockSize() doubles from this DoubleDataSource, and copy them into target, starting from targetPos.

Overrides:

readBlock in class BlockwiseDoubleDataSource

Parameters:

target - the double array to write into

targetPos - position in target where to start writing

Returns:

the amount of data actually delivered. If 0 is returned, all further calls will also return 0 and not copy anything.
