| Methods Summary |
|---|
| public void | addFileset(org.apache.tools.ant.types.FileSet set)Adds a set of files to archive.
if (filesets.size() > 0) {
throw new BuildException("Only one nested fileset allowed");
}
filesets.addElement(set);
|
| protected void | appendFiles(java.util.Vector files, org.apache.tools.ant.DirectoryScanner ds)Append all files found by a directory scanner to a vector.
String[] dsfiles = ds.getIncludedFiles();
for (int i = 0; i < dsfiles.length; i++) {
files.addElement(dsfiles[i]);
}
|
| protected void | checkConfiguration()Check if the attributes and nested elements are correct.
if (baseDir == null && filesets.size() == 0) {
throw new BuildException("basedir attribute or one "
+ "nested fileset is required!",
getLocation());

| protected org.apache.tools.ant.taskdefs.ExecTask | createExec()Create a new exec delegate. The delegate task is populated so that
it appears in the logs to be the same task as this one.
ExecTask exec = new ExecTask(this);
return exec;
|
| protected java.io.File | createListFile(java.util.Vector files)Creates a list file. This temporary file contains a list of all files
to be included in the cab, one file per line.
This method expects to only be called on Windows and thus
quotes the file names.

|
| public void | setVerbose(boolean verbose)If true, display cabarc output.
