Projects
A project is a container for HCL Link artifacts.
- Flows
  This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
  - Nodes
    - Map Node
      A Map Node invokes an HCL Link map within a flow.
    - Flow Node
      A Flow node invokes a sub-flow within a flow.
    - Source and Target Nodes
      Source and Target Nodes provide HCL Link with an outside-in approach to developing integrations.
    - Request Node
      The Request Node has a single input request terminal and a single output response terminal.
    - Cache Read and Write Nodes
      Cache Read and Cache Write node functionality is described in this section.
      - Configuring Cache Read and Cache Write nodes
        Detailed description of how to configure the Cache Read Node and the Cache Write Node.
      - Cache Read
        The Cache Read node reads key/value pairs from the global cache, or from the flow variables. Optionally, it can delete keys and read from the cache.
      - Cache Write Node
        The Cache Write Node writes key/value pairs to the global cache, or to the flow variables based on the scope property
    - Clone Node
      The Clone Node has one input and two output terminals.
    - Decision Node
      The Decision Node routes input data to the true, or false terminals depending upon the condition.
    - Fail Node
      The Fail Node causes the flow execution to fail.
    - Format Converter Node
      The Format Converter Node can be used to quickly convert data from one format to another.
    - JSON Read Node
      This documentation describes the function and use of the JSON Read Node.
    - JSON Transform Node
      The JSON Transform node is used to transform JSON documents from one form to another.
    - Java Node
      The Java Node invokes a Java class, thus performing user defined functionality based on the properties specified for the Java class to act on the input.
    - Join Node
      The Join Node gathers the individual results and appends to a single output file or terminal.
    - Log Node
      The Log Node logs the raw data from the node input into the file and propagates the data from the input to the output terminal.
    - Passthrough Node
      The Passthrough Node propagates data from the input to the output terminal.
    - REST Client Node
      The REST Client Node provides a simple and powerful way to access REST services.
    - Route Node
      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 Node
      The Sleep Node suspends the execution of the flow for the specified number of milliseconds
    - Split Node
      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.
  - Terminals
  - Flow terminals
    Flow terminals represent the inputs and outputs to a flow. Every node has input and/or ouptut terminals.
  - Scheduled flows
    This documentation describes the options for defining the flow schedule.
  - 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.
  - Create a flow
    Steps required to create a flow.
  - Running flows in the Designer
    When you develop a flow in the Flow Designer you can run the flow directly from the Designer either in Link, or on a different runtime environment.
- Maps
  Maps define input and output specifications and mapping rules for data transformation.
- Schemas
  Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
- Connections and Actions
  This documentation describes connections and actions.
- Files
  Files are used in various places within HCL Link. HCL Link allows files to be uploaded to the HCL Linkserver.
