Interface PortDefinition

@Immutable
public interface PortDefinition

Definition of an input or output port on a node. Used to describe the node's interface for client rendering. Port IDs are simple names (e.g., "interval", "message", "bot"). The port type is stored separately in the type() field.

Method Details

execIn

static PortDefinition execIn()

Creates an execution input port.

execOut

static PortDefinition execOut()

Creates an execution output port.

input

static PortDefinition input(String id,
 String displayName,
 PortType type,
 String description)

Creates a required input port.

Parameters:

id - simple port name (e.g., "interval", "target")

inputWithDefault

static PortDefinition inputWithDefault(String id,
 String displayName,
 PortType type,
 String defaultValue,
 String description)

Creates an optional input port with a default value.

Parameters:

id - simple port name (e.g., "interval", "message")

output

static PortDefinition output(String id,
 String displayName,
 PortType type,
 String description)

Creates an output port.

Parameters:

id - simple port name (e.g., "success", "count")

listInput

static PortDefinition listInput(String id,
 String displayName,
 PortType elementType,
 String description)

Creates a list input port with element type.

Parameters:

id - simple port name (e.g., "items", "targets")

listOutput

static PortDefinition listOutput(String id,
 String displayName,
 PortType elementType,
 String description)

Creates a list output port with element type.

Parameters:

id - simple port name (e.g., "results", "bots")

id

String id()

displayName

String displayName()

type

PortType type()

required

@Default
default boolean required()

defaultValue

@Nullable String defaultValue()

description

@Default
default String description()

elementType

@Nullable PortType elementType()

multiInput

@Default
default boolean multiInput()

Whether this input accepts multiple connections (Blender-style multi-input). When true, all connected values are collected into a list. NOTE: The reactive engine does not yet implement multi-input collection.

multiInput

static PortDefinition multiInput(String id,
 String displayName,
 PortType type,
 String description)

Creates a multi-input port that accepts multiple connections. All connected values are collected into a list.

Parameters:

id - simple port name
