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
.
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

array for which the call should return the sibling member count.hPos

java.lang.Object getMemberMetadata(int edge, int[] hPos, int memberLayer, int hIndex, java.lang.String type) throws EdgeOutOfRangeException, LayerOutOfRangeException, SliceOutOfRangeException
The user of this method makes the following calls:
getMemberSiblingCount
to retrieve the number of sibling members for a specified tree of members.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)
.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

int[] getMemberHPos(int edge, int layer, int slice) throws EdgeOutOfRangeException, LayerOutOfRangeException, SliceOutOfRangeException
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.

DataAccess
reference. Provides an opportunity for cleaning up the cursor when a caller is finished with it.
Views should not call this method for normal DataAccess instances, because calling this method makes the DataAccess reference unavailable to other presentation beans that might be using it. This method is useful only in special cases where a caller has wrapped a DataAccess around a private single-layer cursor.
The implementor may or may not implement this method, depending on the underlying cursor.
