Returns the document offset at which the receiver would insert its proposal. |
CharSequence |
getPrefixCompletionText(IDocument document,
int completionOffset)
Returns the string that would be inserted at the position returned from getPrefixCompletionStart(IDocument, int) if this proposal was
applied. |
int |
getRelevance()
Returns the relevance. |
Point |
getSelection(IDocument document)
Returns the new selection after the proposal has been applied to the given document in absolute document coordinates. |
char[] |
getTriggerCharacters()

boolean |
isValidFor(IDocument document,
int offset)
Returns whether this completion proposal is valid for the given position in the given document. |
void |
selected(ITextViewer viewer,
boolean smartToggle)
Called when the proposal is selected. |

A document change can trigger other document changes, which have
to be taken into account when calculating the new selection. Typically,
this would be done by installing a document listener or by using a
document position during ICompletionProposal.apply(IDocument)
