Interface CompletionProvider<T>

All Known Implementing Classes:

ExpressionEditSupport, FileCompletionProvider, InsightManager, StringCompletionProvider

public interface CompletionProvider<T>

A field insight provider is responsible for providing the insight completion list for an CompletionTextField.

T is the type of object representing each cell in the insight list (e.g. String, File)

Method Summary

void	completeInsight(javax.swing.text.Document doc, int pos, T insightObject) Complete insight for the specified position in the specified document, using the specified insight object.
javax.swing.ListCellRenderer	getCellRenderer() Get the cell renderer used for the completion list this provider handles.
T[]	getInsightData(javax.swing.text.Document doc, int pos) Get insight data for the specified position in the specified document.
boolean	handlesInsight(javax.swing.text.Document doc, int pos) Does this provider handle insight for the specified document? This method is normally called when an insight trigger of some kind happens (e.g.
boolean	isAutoPopupChar(char c) Should the specified character trigger an automatic popup completion list that might be handled by this insight provider?

Method Detail

getCellRenderer

javax.swing.ListCellRenderer getCellRenderer()

Get the cell renderer used for the completion list this provider handles.

Returns:

a list cell renderer.

handlesInsight

boolean handlesInsight(javax.swing.text.Document doc,
                       int pos)

Does this provider handle insight for the specified document? This method is normally called when an insight trigger of some kind happens (e.g. a delay timer for popup insight has expired, or the user explicitly requested insight). The implementation should examine the text in the document, based on the specified caret position, and decide whether it will handle insight for this location. If so, it should return true.

Parameters:

doc - the document of the component to provide insight for

pos - the current caret position within the document

Returns:

true if this provider can provide an insight list for the specified location in the document.

getInsightData

T[] getInsightData(javax.swing.text.Document doc,
                   int pos)

Get insight data for the specified position in the specified document.

Parameters:

doc - the document to provide insight for

pos - the current caret position within the document

Returns:

an array of insight objects.

completeInsight

void completeInsight(javax.swing.text.Document doc,
                     int pos,
                     T insightObject)

Complete insight for the specified position in the specified document, using the specified insight object.

Parameters:

doc - the document to complete

pos - the position to complete at

insightObject - the insight object to complete with

isAutoPopupChar

boolean isAutoPopupChar(char c)

Should the specified character trigger an automatic popup completion list that might be handled by this insight provider?

Parameters:

c - the character before the caret position.
