Method Detail

read

public int read(byte[] b,
                int offset,
                int length)

Overrides:

read in class java.io.InputStream

skip

public long skip(long length)

Overrides:

skip in class java.io.InputStream

readSkipInternal

private int readSkipInternal(byte[] b,
                             int offset,
                             int length)

Internal implementation of read and skip. If b != null, then read the next length bytes into the buffer b at offset offset. If b == null, then skip the next length bytes.

This method assumes that all error checking has already happened.

Returns the actual number of bytes read or skipped.

read

public int read()
         throws java.io.IOException

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException

available

public int available()
              throws java.io.IOException

Overrides:

available in class java.io.InputStream

Throws:

java.io.IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class java.io.InputStream

mark

public void mark(int readAheadLimit)

Overrides:

mark in class java.io.InputStream

reset

public void reset()

Overrides:

reset in class java.io.InputStream

initialize

private void initialize()

Common initialization code used by both the constructor and reset()

advanceIfCurrentPieceFullyRead

private void advanceIfCurrentPieceFullyRead()

Skips to the next piece if we have read all the data in the current piece. Sets currentPiece to null if we have reached the end of the input.
