## org.gjt.sp.jedit.search
Class SearchAndReplace

    java.lang.Object
      org.gjt.sp.jedit.search.SearchAndReplace

    public class SearchAndReplace

extends java.lang.Object

Class that implements regular expression and literal search within jEdit buffers.

There are two main groups of methods in this class:

- Property accessors - for changing search and replace settings.
- Actions - for performing search and replace.

The "HyperSearch" and "Keep dialog" features, as reflected in checkbox options in the search dialog, are not handled from within this class. If you wish to have these options set before the search dialog appears, make a prior call to either or both of the following:

     jEdit.setBooleanProperty("search.hypersearch.toggle",true);
     jEdit.setBooleanProperty("search.keepDialog.toggle",true);

If you are not using the dialog to undertake a search or replace, you may call any of the search and replace methods (including `hyperSearch(View)`) without concern for the value of these properties.
