- File Interfaces:
- Java supports the use of Interfaces.
- An interface is a definition of the methods that will be present in any
implementing class.
- A class can implement more than one interface if it so chooses, it just needs to
provide all of the methods required by all of the implemented interfaces.
- An interface can be thought of as a guaranteed contract stating
that "by implementing this interface I guarantee this class will implement
these methods specified by the interface."
- This allows the interface to be used as a reference type that allows any
class implementing the interface to be used without altering the code.
- NeXtMidas makes use of interfaces for plotting and listing files.
- Any file whose handler implements
PlotFile can be plotted
by PLOT .
- Any file whose handler implements
ListFile can be listed
by LIST2 .
X-Midas Users Take Note: |
File support for X-Midas is part of the system libraries and can not be modified without
altering the X-Midas baseline. In NeXtMidas option trees can add their own file handlers,
at run-time, without altering the NeXtMidas baseline.
