Constructor Detail

DataPipe

public DataPipe()

Method Detail

reset

public void reset()

Reset the buffer. Does not resize it back to a smaller size -- if it has ballooned it will stay large, though it will no longer have wasted space in it. If you wish to make the buffer a more manageable size, create a new DataPipe instead.

size

public int size()

Returns the total size of the buffer.

numWritten

public int numWritten()

Returns the number of elements written to the buffer so far (after the last reset()).

numRead

public int numRead()

Returns the number of elements read from the buffer so far (after the last reset()).

copy

public static java.lang.Object copy(java.io.Serializable obj)
                             throws java.io.IOException,
                                    java.lang.ClassNotFoundException
