Class RemoveTypes

java.lang.Object

stream.data.RemoveTypes

All Implemented Interfaces:

Processor

public class RemoveTypes
extends Object
implements Processor

This processor removes key/value pairs from the processed items that have values matching a give set of types. This allows for example to remove all entries from items that are of type `java.lang.Double`.

If an additional pattern of `keys` is provided, then only the matching keys will be checked for removal and any non-matching keys are guaranteed to remain in the item untouched.
