Interface IConstantNode

Interface for a specialized node that outputs a fixed value of a specific data type.

Namespace: Unity.GraphToolkit.Editor
Assembly: Unity.GraphToolkit.Editor.dll
Syntax
public interface IConstantNode : INode
Remarks

Use constant nodes to represent a static, predefined value in the graph. This value remains unchanged and is typically used to feed constant input into computations. To retrieve the value, use TryGetValue<T>(out T). This method is type-safe and provides access to the node’s value if the type matches. The dataType property identifies the constant's type.

Properties

dataType

The data type of the constant node's value.

Declaration
Type dataType { get; }
Property Value
Type Description
Type
Remarks

The type returned by this property indicates the kind of value the constant node holds, such as float, int, string, or a custom type.

Methods

TryGetValue<T>(out T)

Attempts to retrieve the value of the constant node as the specified type.

Declaration
bool TryGetValue<T>(out T value)
Parameters
Type Name Description
T value

The output parameter that holds the value if the conversion is successful.
Returns
Type Description
bool

true if the value was successfully retrieved and cast to T; otherwise, false.
Type Parameters
Name Description
T

The type to retrieve the value as.
Remarks

This method provides type-safe access to the constant's stored value. It performs a type check and conversion internally. If the value cannot be cast to T, the method returns false and value is set to the default value of T.
