Eclipse Platform
Release 3.5

org.eclipse.jface.text
Interface IFindReplaceTarget


public interface IFindReplaceTarget

Defines the target for finding and replacing strings.

The two main methods are findAndSelect and replaceSelection. The target does not provide any way to modify the content other than replacing the selection.

In order to provide backward compatibility for clients of IFindReplaceTarget, extension interfaces are used as a means of evolution. The following extension interfaces exist:

  • IFindReplaceTargetExtension since version 2.0 introducing the notion of find/replace session and of a find/replace scope. In additions, in allows clients to replace all occurrences of a given find query.
  • IFindReplaceTargetExtension3 since version 3.0 allowing clients to specify search queries as regular expressions.

Clients of a IFindReplaceTarget that also implements the IFindReplaceTargetExtension have to indicate the start of a find/replace session before using the target and to indicate the end of the session when the target is no longer used.

IFindReplaceTargetExtension, IFindReplaceTargetExtension3

canPerformFind

boolean canPerformFind()

Searches for a string starting at the given widget offset and using the specified search directives. If a string has been found it is selected and its start offset is returned.

Replaced by IFindReplaceTargetExtension3.findAndSelect(int, String, boolean, boolean, boolean, boolean).

Parameters:
widgetOffset - the widget offset at which searching starts
findString - the string which should be found
searchForward - true searches forward, false backwards
caseSensitive - true performs a case sensitive search, false an insensitive search

isEditable

boolean isEditable()
Returns whether this target can be modified.

Returns:
true if target can be modified
