Constructor Detail

MemoryDataStream

public MemoryDataStream(byte[] data,
                        int offset,
                        int length)

Method Detail

subStream

public MemoryDataStream subStream(long subOffset,
                                  long subLength)

Specified by:

subStream in interface DataStream

getPosition

public long getPosition()

Specified by:

getPosition in interface DataStream

isDone

public boolean isDone()

Specified by:

isDone in interface DataStream

length

public long length()

Specified by:

length in interface DataStream

seek

public void seek(long offset)

Description copied from interface: DataStream

Seeks forward into the stream to a particular byte offset (reverse seeks are not allowed). The offset is relative to the start position of this data stream, not the beginning of the file.

Specified by:

seek in interface DataStream
