           throws IOException

Description copied from interface: Source_1_0

Closes this iterator and releases any system resources associated with it.

No read() operation must be invoked after close().

Specified by:

close in interface Closeable

Specified by:

close in interface Source_1_0

Specified by:

close in class Reader

Throws:

IOException - if an I/O error occurs.

read

public int read(char[] destination,
                int offset,
                int length)
         throws IOException

Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.

Specified by:

read in class Reader

Parameters:

destination - Destination buffer

offset - Offset at which to start storing characters

length - Maximum number of characters to read
