Method Detail

add

public void add(IJavaElement element)

Description copied from interface: IRegion

Adds the given element and all of its descendents to this region. If the specified element is already included, or one of its ancestors is already included, this has no effect. If the element being added is an ancestor of an element already contained in this region, the ancestor subsumes the descendent.

Specified by:

add in interface IRegion

Parameters:

element - the given element

See Also:

IRegion.add(IJavaElement)

contains

public boolean contains(IJavaElement element)

Description copied from interface: IRegion

Returns whether the given element is contained in this region.

Specified by:

contains in interface IRegion

Parameters:

element - the given element

Returns:

true if the given element is contained in this region, false otherwise

getElements

public IJavaElement[] getElements()

Description copied from interface: IRegion

Specified by:

getElements in interface IRegion

Returns:

the top level elements in this region

remove

public boolean remove(IJavaElement element)

Description copied from interface: IRegion

Removes the specified element from the region and returns true if successful, false if the remove fails. If an ancestor of the given element is included, the remove fails (in other words, it is not possible to selectively exclude descendants of included ancestors).

Specified by:

remove in interface IRegion

Parameters:

element - the given element

Returns:

true if successful, false if the remove fails

See Also:

IRegion.remove(IJavaElement)

removeAllChildren

protected void removeAllChildren(IJavaElement element)

Removes any children of this element that are contained within this region as this parent is about to be added to the region.

Children are all children, not just direct children.

toString

public java.lang.String toString()

Returns a printable representation of this region.

Overrides:

toString in class java.lang.Object
