String

This node stores and manages a text string.

The String node holds a text value that can be updated, read, and monitored for changes.

The String node is a variable container for text data. It stores a string value and provides mechanisms to update it either immediately or upon a signal trigger. It also provides the length of the string as a convenient output.

Inputs

General

Data	Description
Value	The text string to store. Default: "" (empty string).

Actions

Signal	Description
Set	Triggers the update of the stored value. If connected, the Value input is buffered until this signal is received.

Outputs

Data

Data	Description
Value	The currently stored string value.
Length	The number of characters in the stored string.

Signals

Signal	Description
Changed	Triggered whenever the stored value changes (i.e., new value is different from old value).
Stored	Triggered when the Set action is completed, regardless of whether the value changed.

Usage

Use the String node to store text states, user inputs, or configuration values.

Modes of Operation

1. Direct Update (Default):
   • Leave the Set input disconnected.
   • Any change to the Value input immediately updates the stored value and triggers the Changed signal.
2. Explicit Update (Buffered):
   • Connect a signal to the Set input.
   • Changes to the Value input are "buffered" internally.
   • The stored value only updates (and outputs change) when the Set signal is triggered.

Example Use Cases

1. User Name: Store a user's name and display it in multiple places.
2. Input Buffering: Connect a Text Input field to Value and a "Submit" button to Set. The String node will only update when the button is clicked.
3. Character Count: Use the Length output to validate input size (e.g., "Password must be at least 8 characters").

Detailed Behavior

• Type Casting: Any input provided to Value is automatically converted to a string (e.g., 123 becomes "123").
• Change Detection: The Changed signal only fires if the new value is strictly different from the current value.
• Stored Signal: The Stored signal fires every time Set is triggered, even if the value remains the same.

Troubleshooting

• Value Not Updating: If you have connected a wire to the Set input, the node enters "Explicit Update" mode. You must trigger the Set signal for the value to update.
