The sum of all the members' values for this method, within a specified slice, should not exceed the value that getLayerCount returns for the specified edge.

This method is useful only in cases of asymmetry where the members on an edge do not all cover one layer and have a depth of 1. On a symmetric edge, all members have a member depth of 1.

This implementation returns 0.

Specified by:
getMemberDepth in interface CDFDataAccess
Overrides:
getMemberDepth in class DataAccessAdapter
Parameters:

getMemberLogicalLayer

public int getMemberLogicalLayer(int edge,
                                 int layer,
                                 int slice)

                                 SliceOutOfRangeException
Description copied from class: DataAccessAdapter
Retrieves the logical layer to which the member at the specified edge, physical layer, and slice location belongs. If a particular member spans more than one physical layer at the specified slice, then passing in any of the spanned physical layer positions for the layer parameter should yield the same logical layer.

The value returned by this method can be used as input to getLayerMetadata and should not exceed the value that is returned by getMemberCount.

Specified by:
getMemberLogicalLayer in interface DataAccess
Overrides:
getMemberLogicalLayer in class DataAccessAdapter
Parameters:
edge - A constant that represents the edge in which to look for the layer and slice. The constants end with _EDGE in DataDirector.
layer - The zero-based index of the physical layer of the member.
slice - An absolute index (zero-based) that indicates the location of a slice along the specified edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.
Returns:
The logical layer of the member within the specified edge.
Throws:
EdgeOutOfRangeException - If edge is too large.
LayerOutOfRangeException - If layer is negative or too large.
SliceOutOfRangeException - If slice is negative or too large.

                                         java.lang.String type)

                                         LayerOutOfRangeException
Returns a String of the form "EdgeXLayerYY", e.g. "Edge1Layer02"
Specified by:
getLayerMetadata in interface CDFDataAccess
Overrides:
getLayerMetadata in class DataAccessAdapter
Parameters:
edge - A constant that represents the edge in which to look for the member metadata. The constants end with _EDGE in DataDirector.
layer - The zero-based index of the layer for which metadata is requested. Uses a depth computation to identify the location of the layer or layer member; 0 is the outer-most layer on the edge. The value for this parameter can be obtained by calling getMemberLogicalLayer.
type - A constant that specifies the kind of metadata that you want. Valid type values are defined in the LayerMetadataMap.
Returns:
The requested metadata. This implementation returns <coded>null.
Throws:
EdgeOutOfRangeException - If edge is too large.
LayerOutOfRangeException - If layer is negative or too large.

                           LayerOutOfRangeException,
                           SliceOutOfRangeException
Description copied from class: DataAccessAdapter
Retrieves the size of a member, that is, the number of slices that the member spans at a specified edge, layer, and slice location (parallel to the direction of the edge). Views use this method to determine the width of a member in a column header or the height of a member in a row header when not in outline form.

The sum of all the unique getMemberExtent values for an edge should not exceed the getEdgeExtent value for the same edge.

This implementation returns 0.

Specified by:
getMemberExtent in interface CDFDataAccess
Overrides:
getMemberExtent in class DataAccessAdapter
Parameters:
edge - A constant that represents the edge in which to look for the layer and slice. The constants end with _EDGE in DataDirector.
layer - The zero-based index of the physical layer of the member whose size will be returned. Valid values are zero to total layers at the specified slice.
slice - An absolute index (zero-based) that indicates the location along the edge of the member whose extent will be returned. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.
Returns:
The number of slices that the member spans at the specified location. This implementation returns zero.
Throws:
EdgeOutOfRangeException - If edge is too large.
LayerOutOfRangeException - If layer is negative or too large
SliceOutOfRangeException - If slice is negative or too large

                               SliceOutOfRangeException
Description copied from class: DataAccessAdapter
Retrieves the absolute number of the first slice that a member spans. Views use this method to determine where to start painting a member label in a row or column header. Views pass the same parameter values to this method and to getMemberExtent.

This implementation returns 0.

Specified by:
getMemberStartSlice in interface CDFDataAccess
Overrides:
getMemberStartSlice in class DataAccessAdapter
Parameters:
edge - A constant that represents the edge in which to look for the layer and slice. The constants end with _EDGE in DataDirector.
layer - The zero-based index of the physical layer of the member whose first slice will be returned. Valid values are zero to total layers at the specified slice.
slice - An absolute index (zero-based) that indicates the location along the specified edge of the member whose starting slice will be returned. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.
Returns:
The absolute index of the first slice that the member spans. This implementation returns zero.
Throws:
EdgeOutOfRangeException - If edge is too large.
LayerOutOfRangeException - If layer is negative or too large.
SliceOutOfRangeException - If slice is negative or too large.

Description copied from interface: DataAccess
Determines if the size of a member, that is, the number of slices that the member spans at a specified edge, layer, and slice location (parallel to the direction of the edge), has been completely calculated. Views use this method to determine whether the width of a member in a column header or the height of a member in a row header when not in outline form will increase further, in order for views to support dynamic span information from implementations.
Specified by:
isMemberExtentComplete in interface DataAccess
Overrides:
isMemberExtentComplete in class DataAccessAdapter
Parameters:
edge - A constant that represents the edge in which to look for the layer and slice. The constants end with _EDGE in DataDirector.
layer - The zero-based number of the physical layer. Valid values are zero to total layers at the specified slice.
slice - An absolute index (zero-based) along the edge. Each member in the innermost layer has a unique slice. In outer layers, any slice that the outer member spans can be used.
Returns:
true if the extent of the specified member has been fully computed, false if not.
Throws:
EdgeOutOfRangeException - If edge is too large.
LayerOutOfRangeException - If layer is negative or too large.
SliceOutOfRangeException - If slice is negative or too large.
