Examples of org.springframework.xd.dirt.stream.StreamDefinition

org.springframework.xd.dirt.stream.StreamDefinition
Represents a model for a data flow in the system. This is typically described with a DSL expression of the form {@code source | [processor | ]* sink}. @see XDParser @author Eric Bottard
