cCJGridCachedDataSource : cCJGridDataSource
- Construct_Object()
  Inherited from cCJGridDataSource
  - IntegerpiRowCount
    Normalized Rows in cache
  - IntegerpiRowOffset
    Unnormalized off set to rows (if not zero)
  - BooleanpbAtTop
    has cache discovered first record
  - BooleanpbAtEnd
    has cache discovered last record
  - IntegerpiMinPageSize
    minimum number of records to page whenever a page is performed
  - IntegerpiMaxCacheSizeAllowed
    max size of cache, 0 - unlimited
  - IntegerpiMaxCacheRange
    internal - used to keep track of the largest range the grid has requested.
  - BooleanpbLoadAll
    if true, load all data with first page event
  - BooleanpbStaticData
    determines if datasource is static - once loaded it does not change
  - HandleServer
    The DD server
  - IntegerpiGridOrdering
    Ordering from Grid. See Ordering for actual order which may differ
  - BooleanpbDDReadMode
    if true we never actually find the record in the dd - just read
  - BooleanpbReverseOrdering
    is data source reversed?
- BooleanDataIsStatic()
  Inherited from cCJGridDataSource
