Each implementation of this abstract class represents an index of filter parameter constants supplied in filter parameters in filter specifications that feature the same event property and operator. For example, a filter with a parameter of "count EQUALS 10" would be represented as index for a property named "count" and for a filter operator typed "EQUALS". The index would store a value of "10" in its internal structure. Implementations make sure that the type of the Object constant in get and put calls matches the event property type.
