Interface FileUtil

public interface FileUtil

Provides a platform-dependent way to open files. Mainly because Mac would prefer that you use java.awt.FileDialog instead of the Swing FileChooser.

Cytoscape Backwards Compatibility (API Interface): We expect that this interface will be used but not implemented by developers using this interface. As such, we reserve the right to add methods to the interface as part of minor version upgrades. We will not remove methods for any changes other than major version upgrades.
