Methods in com.pervasive.datarush.ports.record that return PartitioningFunction

Modifier and Type	Method and Description
PartitioningFunction	KeyDrivenDataDistribution.getBasePartitionFunction() Returns the base partitioning function.
protected PartitioningFunction	UnspecifiedPartialDistribution.getPartitioningFunction()
protected abstract PartitioningFunction	PartialStaticDataDistribution.getPartitioningFunction() Subclasses must override this method to provide the partitioning function to be used
protected PartitioningFunction	KeyDrivenDataDistribution.getPartitioningFunction()
protected PartitioningFunction	BalancedDistribution.getPartitioningFunction()
PartitioningFunction	PartitioningFunction.remapFieldReferences(Map<String,String> oldToNewMapping) Creates a new function, equivalent to the given function, but with all field references renamed according to the given mapping.
PartitioningFunction	HashPartitioningFunction.remapFieldReferences(Map<String,String> oldToNewMapping)

Methods in com.pervasive.datarush.ports.record with parameters of type PartitioningFunction

Modifier and Type	Method and Description
boolean	RangePartitioningFunction.isEquivalentPartitioning(PartitioningFunction other)
boolean	PartitioningFunction.isEquivalentPartitioning(PartitioningFunction other) Returns true iff, given a single row of input, this function is guaranteed to produce the same partitioning as the other function.
boolean	HashPartitioningFunction.isEquivalentPartitioning(PartitioningFunction other)
static KeyDrivenDataDistribution	KeyDrivenDataDistribution.keyed(PartitioningFunction basePartitionFunction, List<String> keys) Returns a distribution that distributes based on the given function of the named key fields.
static KeyDrivenDataDistribution	KeyDrivenDataDistribution.keyed(PartitioningFunction basePartitionFunction, String... keys) Returns a distribution that distributes based on the given function of the named key fields.
static KeyDrivenDataDistribution	KeyDrivenDataDistribution.localKeyed(PartitioningFunction basePartitionFunction, List<String> keys) For advanced use only; this redistributes per-JVM but not across the cluster.
