public final class ContentAssistAction

A content assist action which gets its target from its text editor.

The action is initially associated with a text editor via the constructor, but can subsequently be changed using setEditor.

If this class is used as is, it works by asking the text editor for its text operation target (using getAdapter(ITextOperationTarget.class) and runs the content assist operation on this target.

Since:
2.0
