Method Summary | |
---|---|
String | getError()
Returns any error messages that have been set.
|
abstract boolean | isSelected(File basedir, String filename, File file)
Method that each selector will implement to create their
selection behaviour. |
void | setError(String msg)
Allows all selectors to indicate a setup error. |
void | validate()
Subclasses can use this to throw the requisite exception
in isSelected() in the case of an error condition. |
void | verifySettings() Subclasses can override this method to provide checking of their state. |
Returns: the error condition
Parameters: basedir A java.io.File object for the base directory filename The name of the file to check file A File object for this filename
Returns: whether the file should be selected or not
Parameters: msg The error message any BuildException should throw.
Subclasses can override this method to provide checking of their state. So long as they call validate() from isSelected(), this will be called automatically (unless they override validate()).
Implementations should check for incorrect settings and call setError() as necessary.
