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.
- 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.
  - About schemas
    A schema defines the contents of at least one input that you intend to map or one output you intend to map.
  - Subtypes
  - Schema hierarchy
  - Defining data
  - Objects, types, and classes
  - Testing part of a schema
    You can test a schema by generating test data for an item or a group. The schema designer creates source and compiled maps that generate and validate the test data. The test-data-generation map automatically runs and produces a text file with the sample data. After that, the test-data-validation map automatically runs on the sample data file.

- 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.

Sized attribute

The sized attribute is used on a component in which the value specifies the size (in bytes) of the component immediately following it. The sized attribute can be used on more than one component of a group.

For example, you might have a variable length component with a number immediately preceding it that indicates the length of the component: 10Washington. The size of the component would be 10.

Some important points about using the sized attribute are:

The component with the sized attribute must be defined as an unsigned integer.
If a binary byte stream item does not have a fixed size, the component preceding it must specify its size and the sized attribute must be used on that component.

The size of a component is the number of bytes from the beginning of that component, up to and including the end of the component. If a component has a series range (such as [1:3]), the size includes all of the members in the series of that component. If a delimiter separates each member of that series, the delimiters must be included in the size. Also, if release characters appear in the component, they must be included in the size.

The size does not include delimiters that separate one component type from the next.
