Ctor.

Parameters:

indexProps - - array of property names with the first dimension suplying the number of distinct indexes. The second dimension can be empty and indicates a full table scan.

optIndexCoercionTypes - - array of coercion types for each index, or null entry for no coercion required

rangeProps - range props

optRangeCoercionTypes - coercion for ranges

unique - whether index is unique on index props (not applicable to range-only)

advancedIndexProvisionDesc - advanced indexes
