Examples of org.eclipse.jface.text.FindReplaceDocumentAdapter.find()

org.eclipse.jface.text.FindReplaceDocumentAdapter.find()
Returns the location of a given string in this adapter's document based on a set of search criteria. @param startOffset document offset at which search starts @param findString the string to find @param forwardSearch the search direction @param caseSensitive indicates whether lower and upper case should be distinguished @param wholeWord indicates whether the findString should be limited by white spaces asdefined by Character.isWhiteSpace. Must not be used in combination with regExSearch. @param regExSearch if true findString represents a regular expressionMust not be used in combination with wholeWord. @return the find or replace region or null if there was no match @throws BadLocationException if startOffset is an invalid document offset @throws PatternSyntaxException if a regular expression has invalid syntax
