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.

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.

                                 SliceOutOfRangeException

Description copied from class: DataAccessAdapter

Retrieves the count of all the sibling members at a specified logical layer based on a series of relative indexes for each logical layer down to the specified logical layer. This method is useful in populating a page control for a view. For an example, consider the following column header.

June							July
Tents			Canoes				Tents			Canoes
NY	Boston	LA	Toronto	Winnepeg	NY	LA	NY	Boston	LA	Toronto	Winnepeg

A caller can use this method to find the number of Geography values (that is, sibling members) under the members July and Tents. This count is 3 (for NY, Boston, and LA). The hPos and memberLayer parameters for this example are as follows:

• hPos, an array of relative indexes, holds an entry for July, Tents, and any one of the siblings that are to be counted. A valid hPos in this example must contain indexes for at least layers 0, 1, and 2. Valid arrays for this example could be any of the following: {1,0,0} or {1,0,1} or {1,0,2).
• memberLayer, which identifies the layer at which to count the siblings, must be 2.

Note: The value that is returned by this method provides the upper limit to the hIndex that a caller passes in getMemberMetadata.

This implementation returns 0.

Specified by:

getMemberSiblingCount in interface DataAccess

Overrides:

getMemberSiblingCount in class DataAccessAdapter

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

hPos - An array that contains an index for the member values at each layer up to and including the layer of the sibling members that are to be counted. These indexes are relative to the number of members at each layer. When a member spans more than one layer, any layers beyond the starting layer should have their place held by a -1 index.

memberLayer - The index into the hPos array for which the call should return the sibling member count.

Returns:

The number of sibling members that are found on the specified edge at the location that is specified by hPos and memberLayer. In the example, this method returns 3 (for the siblings NY, Boston, and LA). This implementation returns 0.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If memberLayer is too large.

SliceOutOfRangeException - If any slice in hPos is too large.

Description copied from class: DataAccessAdapter

Retrieves the specified type of metadata for the member at a specified location. For example, this method is useful for retrieving labels for display in views.

The user of this method makes the following calls:

• Calls getMemberSiblingCount to retrieve the number of sibling members for a specified tree of members.
• Calls this method once for each sibling member to retrieve the specified metadata for that member.

The call for this method uses the same hPos and memberLayer parameters as found in getMemberSiblingCount to specify the parent tree of members. Each call of this method also uses the hIndex parameter that indicates the specific sibling member for which to return metadata. Valid values for hIndex range from 0 to (getMemberSiblingCount() - 1).

Specified by:

getMemberMetadata in interface DataAccess

Overrides:

getMemberMetadata in class DataAccessAdapter

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

hPos - An array of relative indexes, organized by logical layer, for the parent tree of members above the sibling member that is specified by hIndex. The array includes entries for layer 0 through at least the layer that is specified by memberLayer.

memberLayer - The zero-based index into the hPos array for which the call should address the set of sibling members.

hIndex - The zero-based index of a sibling member relative to its siblings. This index specifies the sibling member for which to return the specified metadata.

type - A constant that specifies the kind of metadata to return. Valid type values are defined in MetadataMap.

Returns:

The requested metadata for the member at the specified location. This implementation returns <coded>null.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If memberLayer is too large.

SliceOutOfRangeException - If any slice in hPos is too large, or if the hIndex is too large.

Description copied from class: DataAccessAdapter

Retrieves, for the specified edge, the hierarchical address of the location that is defined by the implementor as the "current" location. The row and column edges of view do not require support for the concept of a current location. This concept is usually associated with a paging control on the page edge of a view.

Specified by:

getEdgeCurrentHPos in interface DataAccess

Overrides:

getEdgeCurrentHPos in class DataAccessAdapter

Parameters:

edge - A constant that represents the edge of interest. The constants end with _EDGE in DataDirector.

Returns:

The hPos array that represents the current location on the specified edge. When this method is called for the page edge, the hPos that represents the page that is currently displayed in a Crosstab. This implementation returns <coded>null.

Throws:

EdgeOutOfRangeException - If the parameter edge is not valid.

                    throws EdgeOutOfRangeException,
                           LayerOutOfRangeException,
                           SliceOutOfRangeException

Description copied from class: DataAccessAdapter

Retrieves the hierarchical address for an absolute address that is specified as edge, physical layer, and slice. This method constructs an array that can be used in creating the hPos parameter in calls such as getMemberSiblingCount and getMemberMetadata.

As an example, this method can retrieve an array of indexes from a page edge. The array includes an index for each layer in the page edge. Consider pivoting the following column header to a page edge.

June							July
Tents			Canoes				Tents			Canoes
NY	Boston	LA	Toronto	Winnepeg	NY	LA	NY	Boston	LA	Toronto	Winnepeg

If the current page displayed June, Canoes, and Winnepeg, this method would return the array {0,1,1}. June is at index 0 in layer 0. Canoes is at index 1 in layer 1 under June. Winnepeg is at index 1 in layer 2 under Canoes. To find the number of members under Canoes under June, call getMemberSiblingCount with the array {0,1,1} and the memberLayer parameter 2.

Specified by:

Returns:

An array of relative indexes. There is one index for each layer in the edge up to and including the layer argument, with -1 representing non-starting layers when a member happens to span more than one layer. This implementation returns <coded>null.

Throws:

EdgeOutOfRangeException - If edge is too large.

LayerOutOfRangeException - If memberLayer is too large.

SliceOutOfRangeException - If any slice in hPos is too large
