Class WriteableStorage

java.lang.Object
com.pervasive.datarush.operators.group.WriteableStorage
public final class WriteableStorage extends Object
Storage class by which a custom aggregator can storage its internals. An aggregator's internals correspond element-by-element with the internalTypes that the aggregator declared. Needed only for writing custom Aggregator; consumers of the API should not need to use this class.
