| org.eclipse.ui.internal.ide.dialogs.ResourceComparator
| ResourceComparator | | public class ResourceComparator extends ViewerComparator (Code) | | Sorter for viewers that display items of type IResource.
The sorter supports two sort criteria:
NAME: Folders are given order precedence, followed by files.
Within these two groups resources are ordered by name. All name comparisons
are case-insensitive.
TYPE: Folders are given order precedence, followed by files.
Within these two groups resources are ordered by extension. All extension
comparisons are case-insensitive.
This class may be instantiated; it is not intended to be subclassed.

| Constructor Summary | |
| public | ResourceComparator(int criteria)
Creates a resource sorter that will use the given sort criteria. |
| Method Summary | |
| protected int | classComparison(Object element)
Returns an integer value representing the relative sort priority of the
given element based on its class. | | public int | compare(Viewer viewer, Object o1, Object o2)
| | protected int | compareClass(Object element1, Object element2)
Returns a number reflecting the collation order of the given elements
based on their class. | | protected int | compareNames(IResource resource1, IResource resource2)
Returns a number reflecting the collation order of the given resources
based on their resource names. | | protected int | compareTypes(IResource resource1, IResource resource2)
Returns a number reflecting the collation order of the given resources
based on their respective file extensions. | | public int | getCriteria()
Returns the sort criteria of this this sorter. |
| NAME | | final public static int NAME(Code) | | Constructor argument value that indicates to sort items by name.
|
| TYPE | | final public static int TYPE(Code) | | Constructor argument value that indicates to sort items by extension.
|
| ResourceComparator | | public ResourceComparator(int criteria)(Code) | | Creates a resource sorter that will use the given sort criteria.
Parameters:
criteria - the sort criterion to use: one of NAME or TYPE |
| classComparison | | protected int classComparison(Object element)(Code) | | Returns an integer value representing the relative sort priority of the
given element based on its class.
- resources (
IResource) - 2
- project references (
ProjectReference) - 1
- everything else - 0
Parameters:
element - the element the sort priority (larger numbers means more important) |
| compareClass | | protected int compareClass(Object element1, Object element2)(Code) | | Returns a number reflecting the collation order of the given elements
based on their class.
Parameters:
element1 - the first element to be ordered
Parameters:
element2 - the second element to be ordered a negative number if the first element is less than the second element; the value 0 if the first element isequal to the second element; and a positive number if the firstelement is greater than the second element |
| compareNames | | protected int compareNames(IResource resource1, IResource resource2)(Code) | | Returns a number reflecting the collation order of the given resources
based on their resource names.
Parameters:
resource1 - the first resource element to be ordered
Parameters:
resource2 - the second resource element to be ordered a negative number if the first element is less than the second element; the value 0 if the first element isequal to the second element; and a positive number if the firstelement is greater than the second element |
| compareTypes | | protected int compareTypes(IResource resource1, IResource resource2)(Code) | | Returns a number reflecting the collation order of the given resources
based on their respective file extensions. Resources with the same file
extension will be collated based on their names.
Parameters:
resource1 - the first resource element to be ordered
Parameters:
resource2 - the second resource element to be ordered a negative number if the first element is less than the second element; the value 0 if the first element isequal to the second element; and a positive number if the firstelement is greater than the second element |
| getCriteria | | public int getCriteria()(Code) | | Returns the sort criteria of this this sorter.
the sort criterion: one of NAME or TYPE |
