public class BaseSearchLabelProvider extends org.eclipse.jface.viewers.BaseLabelProvider
A base implementation of a label provider for an AbstractTextSearchViewPage. Clients are intended to extend this class and implement interfaces such as ILabelProvider, IStyledLabelProvider, IColorProvider by using methods provided in the base implementation. For potential match support, subclasses need to override isPotentialMatch(Match).

    • getForeground

      public org.eclipse.swt.graphics.Color getForeground(Object element)
      Provides a foreground color for the given element.

      Default implementation returns the foreground color for potential matches as set in the search preferences if the given element has potential matches and emphasizing of potential matches is enabled in the search preferences. Otherwise, null is returned.

      Parameters:
      element - the element
      Returns:
      the foreground color for the element, or null to use the default foreground color
    • getBackground

      public org.eclipse.swt.graphics.Color getBackground(Object element)
      Provides a background color for the given element.

      Default implementation returns null.

      Parameters:
      element - the element
      Returns:
      the background color for the element, or null to use the default background color
    • getLabelWithCounts

      public String getLabelWithCounts(Object element, String elementName)
      Decorates the given element name with the match count information for the given element.

      Default implementation provides counts for both exact and potential matches (if any).

      Parameters:
      element - not null
      elementName - not null
      Returns:
      the element label with match counts (never null)
    • getColoredLabelWithCounts

      public org.eclipse.jface.viewers.StyledString getColoredLabelWithCounts(Object element, org.eclipse.jface.viewers.StyledString coloredName)
      Decorates the given styled string with the match count information for the given element.

      Default implementation delegates to getLabelWithCounts(Object, String) and applies StyledString.COUNTER_STYLER to the result.

      Parameters:
      element - not null
      coloredName - not null
      Returns:
      the element label with match counts (never null)
    • isPotentialMatch

      protected boolean isPotentialMatch(org.eclipse.search.ui.text.Match match)
      Returns whether the given match is a potential match.

      Default implementation returns false, which effectively disables potential match support provided in BaseSearchLabelProvider. To enable it, subclasses need to override this method.

      Parameters:
      match - never null
      Returns:
      true if the given match is a potential match, and false if it is an exact match.
