* NOTE: The Record API is marked as deprecated. It is not being developed anymore and will be removed from the code at some point. See FLINK-1106 for more details. Operator for input nodes which reads data from collection or iterator. Use this operator if you want to use a collection of data from the application as an input for a job to the cluster. There are two main ways to use the CollectionDataSource: Using an Iterator that is also Serializable.

 CollectionDataSource source = new CollectionDataSource(mySerializableIterator, "IterSource");
 

Using a Collection of Java Objects.

 CollectionDataSource source2 = new CollectionDataSource(new List<String>(), "Collection source");
 

Note that you can as many elements as you want to the constructor:

 CollectionDataSource("Varargs String source", "some", "strings", "that", "get", "distributed");
 

The only limitation is that the elements need to have the same type.

                    Object... data)

Deprecated.

Creates a new instance for the given input using the given input format.

Parameters:

f - The CollectionInputFormat implementation used to read the data.

data - The input data. It should be a collection, an array or a serializable iterator.

name - The given name for the Pact, used in plans, logs and progress messages.

CollectionDataSource

public CollectionDataSource(String name,
                    Object... args)

Deprecated.

Creates a new instance for the given input using the given input format. The contract has the default name. The input types will be checked. If the input types don't agree, an exception will occur.

Parameters:

args - The input data. It should be a collection, an array or a serializable iterator.

name - The given name for the Pact, used in plans, logs and progress messages.
