Composite
public Composite()
accept
public void accept(Visitor visitor)
- Specified by:
- accept in interface Component
add
public int add(Component addThis)
throws java.lang.IllegalArgumentException,
java.lang.IllegalStateException
- Add a new component to a composite. Returns the index of the added
component. This index number may later change if earlier components are
removed.
- Specified by:
- add in interface Composite
check
public abstract boolean check(Component addition)
throws java.lang.IllegalStateException
- Checks if the component to be added is of correct type. Returns true if
it is, false if it is not. Throws IllegalStateException if this
component is of right type, but cannot be added now (there is already a
max number of such components, for example).
All composites override this to restrict what classes can be added to
them.
- Specified by:
- check in interface Composite
get
public Component get(int number)
throws java.lang.ArrayIndexOutOfBoundsException
- Get returns the wanted child by it's number. If not found, throws
ArrayIndexOutOfBoundsException.
- Specified by:
- get in interface Composite
get
public Component get(Component childClass)
- This function returns the first child x that fullfills (x instanceof
childClass). This is handy for searching Composites and subclasses of
ByteString, but not ByteStrings.
- Specified by:
- get in interface Composite
remove
public boolean remove(Component child)
- Removes the first occurrence of this object. Returns true if the
argument was a component of this composite; false otherwise. Elements
of a higher index are moved one step downwards.
- Specified by:
- remove in interface Composite
iterator
public java.util.Iterator iterator()
- GetEnum returns enumeration of all the children.
- Specified by:
- iterator in interface Composite
size
public int size()
- Specified by:
- size in interface Composite
toString
public java.lang.String toString()
- Overrides:
- toString in class java.lang.Object
