Method Detail

isOnToken

boolean isOnToken()

isSlice

boolean isSlice()

isEQ

boolean isEQ()

isIN

boolean isIN()

isContains

boolean isContains()

isMultiColumn

boolean isMultiColumn()

canEvaluateWithSlices

boolean canEvaluateWithSlices()

Returns true if, when applied to a clustering column, this restriction can be handled through one or more slices alone without filtering. For example, EQ restrictions can be represented as a slice, but CONTAINS cannot.
