Method Details

test

public boolean test(Tuple t)

Specified by:

test in interface Predicate<Tuple>

close

public void close()

Description copied from interface: Realized

Clean up any resources allocated to this Realized thing. This might involve removing temporary files, closing or flushing a network connection to some external service, or terminating some child processes. Note that it's expected that this object won't be used again after being closed.

In some instances, implementations may want to remove references to large (in terms of memory) objects so that they can be garbage collected even if references to the pipeline continue to keep them 'live' in the JVM's object graph

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Realized

getSourceType

public Struct getSourceType()

Description copied from interface: Restrictor

The exact Struct that Tuple's passed to Predicate.test(java.lang.Object) should be of.

Specified by:

getSourceType in interface Restrictor

getPredicate

public Predicate<Tuple> getPredicate()
