trait PredicateOps[Predicate] extends AnyRef

A unified API for predicates, used by BasicCassandraPredicatePushDown.

Keeps all the Spark-specific stuff out of BasicCassandraPredicatePushDown It is also easy to plug-in custom predicate implementations for unit-testing.

Abstract Value Members

  1. abstract def columnName(p: Predicate): String

    Permalink

    Returns the column name of the only column in the predicate.

    Returns the column name of the only column in the predicate. Will throw IllegalArgumentException if predicate is not a single-column predicate.

  2. abstract def isEqualToPredicate(p: Predicate): Boolean

    Permalink

    Returns true for predicates of type: column = value

  3. abstract def isInPredicate(p: Predicate): Boolean

    Permalink

    Returns true for predicates of type: column IN (value1, value2, ...)

  4. abstract def isRangePredicate(p: Predicate): Boolean

    Permalink

    Returns true for predicates of type: column (< | <= | >= | >) value

  5. abstract def isSingleColumnPredicate(p: Predicate): Boolean

    Permalink

    Returns true if the predicate restricts exactly one column.
