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)

Creates a SharedByteArrayInputStream for reading data from a sub-array of the given byte array.

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
