Method Detail

### setRefid

    public void setRefid(Reference r)
                  throws BuildException

  Makes this instance in effect a reference to another PatternSet instance.

  You must not set another attribute or nest elements inside this element if you make it a reference.

  Overrides:
    `setRefid` in class `DataType`
  Parameters:
    `r` - the reference to another patternset.
  Throws:
    `BuildException` - on error.

### addConfiguredPatternset

    public void addConfiguredPatternset(PatternSet p)

  This is a patternset nested element.

  Parameters:
    `p` - a configured patternset nested element.

### createInclude

    public PatternSet.NameEntry createInclude()

  add a name entry on the include list

  Returns:
    a nested include element to be configured.

### createIncludesFile

    public PatternSet.NameEntry createIncludesFile()

  add a name entry on the include files list

  Returns:
    a nested includesfile element to be configured.

### createExclude

    public PatternSet.NameEntry createExclude()

  add a name entry on the exclude list

  Returns:
    a nested exclude element to be configured.

### createExcludesFile

    public PatternSet.NameEntry createExcludesFile()

  add a name entry on the exclude files list

  Returns:
    a nested excludesfile element to be configured.

### setIncludes

    public void setIncludes(java.lang.String includes)

  Appends `includes` to the current list of include patterns. Patterns may be separated by a comma or a space.

  Parameters:
    `includes` - the string containing the include patterns

### setExcludes

    public void setExcludes(java.lang.String excludes)

  Appends `excludes` to the current list of exclude patterns. Patterns may be separated by a comma or a space.

  Parameters:
    `excludes` - the string containing the exclude patterns

### setIncludesfile

    public void setIncludesfile(java.io.File includesFile)
                         throws BuildException

  Sets the name of the file containing the includes patterns.

  Parameters:
    `includesFile` - The file to fetch the include patterns from.
  Throws:
    `BuildException` - on error.

### setExcludesfile

    public void setExcludesfile(java.io.File excludesFile)
                         throws BuildException

  Sets the name of the file containing the excludes patterns.

  Parameters:

    the filtered included patterns.

### getExcludePatterns

    public java.lang.String[] getExcludePatterns(Project p)

  Returns the filtered include patterns.

  Parameters:
    `p` - the current project.
  Returns:
    the filtered excluded patterns.

### hasPatterns

    public boolean hasPatterns(Project p)

  Helper for FileSet classes. Check if there are patterns defined.

  Parameters:
    `p` - the current project.
  Returns:
    true if there are patterns.

### toString
