Examples of Merge

cascading.pipe.Merge
The Merge Pipe allows for multiple branches, with the same fields to be spliced back into a single stream.
The behavior is similar to the {@link GroupBy} merging features, but Merge does not perform any grouping orsorting on keys. Thus, when using a MapReduce platform, no Reducer is required.
Merge is non-blocking and performs no processing. Any number of branches and merges may be performed in a {@link cascading.flow.Flow} without triggering any additional MapReduce jobs on the Hadoop platform.
Unlike {@link HashJoin}, no preference need be made for left-hand or right-hand sided-ness of streams in relation to their sizes. @see GroupBy
com.projity.algorithm.Merge
Merge is a functor which groups time intervals together and calls a vistor object on the resulting merged intervals You can specify a comparator as well to determine whether two intervals are mergeable

org.h2.command.dml.Merge
This class represents the statement MERGE
org.jbpm.graph.node.Merge
TODO is the merge node useful ? i don't think the merge node is useful because every node has an implicit merge in front of it (= multiple transitions can arrive in the same node). maybe we should just leave this in for the sake of workflow patterns ?

ptolemy.domains.de.lib.Merge
A timed merge actor for the DE domain. It merges a set of input signals into a single output signal based on the order of the tags associated with the events of signals. A tag is a tuple of a timestamp (as double) and a microstep or index (as non-negative integer). Tags have a lexicographic order.
This actor has an input port (a multiport) and an output port (a single port). The types of the ports are undeclared and will be resolved by the type resolution mechanism, with the constraint that the output type must be greater than or equal to the input type.
There is a boolean parameter discardEvents associated with this actor, which decides how to handle simultaneously available inputs. Each time this actor fires, it reads the first available tokens from an input channel and sends them to the output port. If the discardEvents parameter is configured to true, then this actor discards all the remaining inputs in the rest of channels. Otherwise, this actor requests refirings at the current time until no more events are left in the channels. By default, the discardEvents parameter is false. @author Edward A.
