public void setError(java.lang.String msg)
msg
- The error message any BuildException should throw.public java.lang.String getError()
public void verifySettings()
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.
public void validate()
public abstract boolean isSelected(java.io.File basedir, java.lang.String filename, java.io.File file)
