Description copied from interface: RandomStream

get the file name to be processed. this file is the raw data to be read, or the input file processed by algorithm.

Specified by:

getFilename in interface RandomStream

Returns:

string null if missing, else the filename from setFilename.

See Also:

RandomStream.getFilename()

setFilename

public void setFilename(String s)

Description copied from interface: RandomStream

set file name to be processed. this file is the raw data to be read, or the input file processed by algorithm.

Specified by:

setFilename in interface RandomStream

Returns:

true if open (still data in stream), else flase

See Also:

RandomStream.setFilename(java.lang.String)

isOpen

public boolean isOpen()

Description copied from interface: RandomStream

check if RandomStream is open

Specified by:

isOpen in interface RandomStream

Returns:
