Constructor Detail

SharedByteArrayInputStream

public SharedByteArrayInputStream(byte[] buf)
Creates a SharedByteArrayInputStream for reading data from the given byte array.

Parameters:
buf - the data carrying byte array

SharedByteArrayInputStream

public SharedByteArrayInputStream(byte[] buf,
                                  int offset,
                                  int length)

Parameters:
buf - the data carrying byte array
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 javax.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 javax.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
