Method Detail

clone

public BKDReader.BKDOnHeapInput clone()

Description copied from class: DataInput

Returns a clone of this stream.

Clones of a stream access the same data, and are positioned at the same point as the stream they were cloned from.

Expert: Subclasses must ensure that clones may be positioned at different points in the input from each other and from the stream they were cloned from.

Overrides:

clone in class BKDReader.BKDInput

getMinLeafBlockFP

long getMinLeafBlockFP()

Specified by:

getMinLeafBlockFP in class BKDReader.BKDInput

ramBytesUsed

long ramBytesUsed()

Specified by:

ramBytesUsed in class BKDReader.BKDInput

getPosition

int getPosition()

Specified by:

getPosition in class BKDReader.BKDInput

setPosition

void setPosition(int pos)

Specified by:

setPosition in class BKDReader.BKDInput

readByte

public byte readByte()
              throws java.io.IOException

Description copied from class: DataInput

Reads and returns a single byte.

Specified by:

readByte in class DataInput

Throws:

java.io.IOException

See Also:

DataOutput.writeByte(byte)

readBytes

public void readBytes(byte[] b,
                      int offset,
                      int len)
               throws java.io.IOException

Description copied from class: DataInput

Reads a specified number of bytes into an array at the specified offset.

Specified by:

readBytes in class DataInput

Parameters:

b - the array to read bytes into

offset - the offset in the array to start storing bytes

len - the number of bytes to read

Throws:

java.io.IOException
