Design Server
The documentation provided here describes how to use the Design Server.
Flows
A flow node invokes a sub flow within a flow. Sub-flows need not be wired to other nodes; it is valid to have a flow that is comprised of multiple sub-flows that each have listeners.
Flows
This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
Nodes
JAVA
Invokes a java class, performing user defined functionality based on the properties specified for the java class to act on the input.

      - Maps
        A map node invokes a LNK map within a flow.

      - Source and Target
        Source and Target nodes provide Link with an outside-in approach to developing integrations. The inside-out approach means that you begin with a map, add inputs and outputs, and then configure these to access resources. Connections might be created in the process. The outside-in approach implements the integration from the opposite direction. You begin with the outside interfaces, then connects them to provide maps and other artifacts.
      - Cache Read and Write
        This documentation describes the function and use of the Cache Read and Cache Write nodes.
      - Clone
        The Clone node has one input and two output terminals. This node clones, or copies the input data from the single input terminal to both output terminals.
      - Decision
      - Fail
        Fails the flow execution.
      - Format Converter
        The Format Converter Node can be used to quickly convert data from one format to another.

        Invokes a java class, performing user defined functionality based on the properties specified for the java class to act on the input.
        Settings
        Following are the Java node settings that user must specify to create a flow definition.

      - Join
        The Join node gathers the individual results and appends to a single output file or terminal.
      - Log
        This node logs the raw data from the node input into the file and propagates the data from the input to the output terminal.
      - REST Client
        The REST Client flow node provides a simple and powerful way to access REST services. It can be used to directly invoke REST APIs or can use prebuilt configurations that define the APIs of the service. The node supports:
      - Route
        The Route node provides a way to route data conditionally to one or more outputs of the node. The node bases decisions by evaluating a condition for a flow variable and determining whether to send the data to output 1 or 2 or both, based on the result of the condition.
      - Sleep
        This node suspends the execution of the flow for the specified number of milliseconds
      - Split
        A Split node should be used when there is a need to split csv data processing. This might occur when csv data processing becomes excessively time consuming. Such time-consuming behavior might occur when you send big csv data to the flow input terminal or it might become memory intense when complex data validation is being performed. The Split node can be used with these, and with other data processing tasks that can be done in parallel.
    - Terminals
    - Flow terminals
    - Scheduled flows
    - Listener
      A Flow that has a Map node as its first node, and uses a File adapter for an input, can enable that node's input to be a Watch.
    - Flow audits
      Flow audits are a way to retrieve more verbose information about a flow instance.
    - Flow variables
      Flow Variables are process data variables that go along with the flow execution, accessible to all nodes in the flow while it is being executed under flow executor/engine context.

- Schema designer
  Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.

JAVA

Invokes a java class, performing user defined functionality based on the properties specified for the java class to act on the input.

The Java node presents a simplified interface to invoke a Java class as part of the flow execution. It enables to perform a custom functionality written in Java programming language and be a part of the flow definition and execution. It is similar to an exit point where user can plug-in their custom functionality as a part of the flow execution to achieve the intended objective and the purpose of the flow.
