    • addExtension

      public void addExtension​(ExtensionAdapter extensionAdapter)
      Adds an extension that this library requires.
      Parameters:
      extensionAdapter - an extension that this library requires.

    • addLibfileset

      public void addLibfileset​(LibFileSet fileSet)
      Adds a set of files about which extensions data will be extracted.
      Parameters:
      fileSet - a set of files about which extensions data will be extracted.

    • addFileset

      public void addFileset​(FileSet fileSet)
      Adds a set of files about which extensions data will be extracted.
      Parameters:
      fileSet - a set of files about which extensions data will be extracted.

    • toExtensions

      public Extension[] toExtensions​(Project proj) throws BuildException
      Extract a set of Extension objects from the ExtensionSet.
      Parameters:
      proj - the project instance.
      Returns:
      an array containing the Extensions from this set
      Throws:
      BuildException - if an error occurs

    • setRefid

      public void setRefid​(Reference reference) throws BuildException
      Makes this instance in effect a reference to another ExtensionSet 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:
      reference - the reference to which this instance is associated
      Throws:
      BuildException - if this instance already has been configured.

    • dieOnCircularReference

      protected void dieOnCircularReference​(java.util.Stack<java.lang.Object> stk, Project p) throws BuildException
      Description copied from class: DataType
      Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

      If one is included, throw a BuildException created by circularReference.

      This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

      The general contract of this method is that it shouldn't do anything if DataType.checked is true and set it to true on exit.

      Overrides:
      dieOnCircularReference in class DataType
      Parameters:
      stk - the stack of references to check.
      p - the project to use to dereference the references.
      Throws:
      BuildException - on error.

    • toString

      public java.lang.String toString()
      Description copied from class: DataType
      Basic DataType toString().
      Overrides:
      toString in class DataType
      Returns:
      the extensions in a string.
