Method Detail

subStream

DataStream subStream(long start,
                     long length)

getPosition

long getPosition()

isDone

boolean isDone()

length

long length()

seek

void seek(long offset)

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.
