offset - the position in the byte array from which to start reading

length - the maximum number of bytes that can be read

Method Detail

getPosition

public long getPosition()

Gets the current postion of the stream as offset from the start postion.

Specified by:

getPosition in interface jakarta.mail.internet.SharedInputStream

Returns:

the current read position in the stream

newStream

public java.io.InputStream newStream(long start,
                                     long end)

Gets a new SharedInputStream as substream from this InputStream.

Specified by:

newStream in interface jakarta.mail.internet.SharedInputStream

Parameters:

start - the start position in the current stream

end - the end position (+1) in the current stream; -1 if the new stream shall end at the same position as this stream

Returns:

the new stream sub stream
