Terminal

Terminal Overview

Terminal is the input and output terminal of the block. Each block must contain at least one terminal. The user can connect a terminal via the connector. The user can connect one input terminal to multiple output terminals. The input terminal is connected only to the output terminal. Input and output terminal data types must be the same to connect.

Input Terminal

The Input terminal gets data from the output terminal.

Output Terminal

The Output terminal transfers data to the input terminal.

Type Casting

All input signals of a block must share the same data type. Flint Visual Programmer simplifies this requirement by automatically upcasting data types when necessary. This ensures compatibility across different input signals without manual intervention.

Flint intelligently handles data type mismatches by converting lower-precision or less complex data types to match the highest precision or most complex data type among the connected inputs. This process is automatic and ensures that operations are performed consistently without errors.

For example:

In an Add Block, if one input terminal is connected to an 8-bit unsigned integer (Uint8) and another to a single-precision float, Flint automatically converts the Uint8 input to a single-precision float and outputs a single precision float.
