Function to retrieve properties of an given EDMpersitentAttrHashTable. This function has variable number of arguments, i.e., it can be invoked with minimum 6 argument and maximum 9 arguments.

Arguments

1	Type	Name	Comment
2	GENERIC	modelId	Specifies the EDMdataModel that locates the actual EDMpersitentAttrHashTable.
3	GENERIC	attrHashTableId	An instanceId that in combination with the argument "modelId" uniquely identifies an EDMpersitentAttrHashTable in an EDMdatabase. The "attrHashTableId" will be returned by a xpxGetPersistentAttrHashTable() operation
4	INTEGER	hashTableWidth	The width (number of buckets) of the actual EDMpersitentAttrHashTable will be returned in this argument.
5	INTEGER	entries	The total number of entries (elements) in the actual EDMpersitentAttrHashTable will be returned in this argument.
6	INTEGER	subEntries	The total number of sub entries (sub elements) in the actual EDMpersitentAttrHashTable will be returned in this argument.
7	INTEGER	databaseBlocks	The total number of database blocks in the EDMdatabase the actual EDMpersitentAttrHashTable occupies will be returned in this argument.
8	LIST OF INTEGER	entriesPerBuckets	Optional argument. When specified, the number of elements per bucket (hash table distribution) will be returned as a LIST of integer. The index in this list is the same as the "bucket index" in the actual EDMpersitentAttrHashTable.
9	LIST OF INTEGER	subEntriesPerBuckets	Optional argument. When specified, the number of sub elements per bucket will be returned as a LIST of integer. The index in this list is the same as the "bucket index" in the actual EDMpersitentAttrHashTable. A "subEntry" in an EDMpersitentAttrHashTable, is an entry that holds an instanceId that share the same string value with other instanceIds. In other words, the number of "subEntries" gives the number of entries with identical string value in the actual bucket.
10	LIST OF INTEGER	databaseBlocksPerBuckets	Optional argument. When specified, the number of database blocks in EDMdatabase occupied per nucket will be returned in the LIST of integer aggregate. The index in this list is the same as the "bucket index" in the actual EDMpersitentAttrHashTable.
