MarkMask

All Known Implementing Classes:

FileMark, FileRemote, FileZip, SelectMask
```
public interface MarkMask_ifc
```
This is a universal interface to mark instances to support selection. It supports up to 32 sources or users for mark. The management of users should be defined at user level. A source is represented by a bit in the 32-bit-value of the mask. Usual only one source for selection may existing. It is possible that two or less more sources do a mark independently. The class SelectMask is the standard implementation. A derived class can inheritance from that class if another superclass isn't necessary. This may be usual for small data classes.

Usage of the oData parameter:
```
 Application
     |--------->MarkMask_ifc
     |                |<|----Implementor
                      |      maybe a table container
                      |             |--oData---------->SelectMask_ifc
                                                           |<|-----------SecondImplementor
                                                           |             maybe an Object
                                                                         which should be
                                                                         selected
 
```
The oData maybe instance of SelectMask_ifc, but maybe another one, depends on the first Implementor.

    - 2013-04-28 Hartmut rename: This interface is called now 'MarkMask_ifc' instead 'SelectMask_ifc'. It is a problem of wording: The instances are only marked, not yet 'selected'. See application of this interface in org.vishia.gral.widget.GralFileSelector: A selected line is the current one or some marked lines.
    - 2013-04-28 Hartmut chg: Use the mask for selection of mark bits.
    - 2013-04-28 Hartmut chg: new parameter data proper to use. Adaption necessary. Left it empty if it don't need.

- Method Detail
  - getMark
```
int getMark()
```
    Returns the selection mask of this object. If the returned value is 0, the object is not selected. If it is not 0, any source (represented by each bit) has selected this source.
    
    Returns:
    
    bits of selection, 0 if it is not selected.
  - setNonMarked
```
int setNonMarked(int mask,
                 java.lang.Object data)
```
    Removes the mark bits of the object for the given source.
    
    Parameters:
    
    mask - The bit which presents the source.
    
    oData - data which are given with this mark. Maybe the mark should be done in this data too. It depends on usage and implementation.
    
    Returns:
    
    The mark bits before this action is done.
  - setMarked
```
int setMarked(int mask,
              java.lang.Object data)
```
    Sets the mark bits of the object for the given source.
    
    Parameters:
    
    mask - The bit which presents the source.
    
    oData - data which are given with this mark. Maybe the mark should be done in this data too. It depends on usage and implementation.
    
    Returns:
    
    The mark bits before this action is done. If it is 0, this source is the only one which has marks the object.
