ICENodePort Class Reference

---

Detailed Description

ICENodePort is the base class for ICENode ports such as ICENodeInputPort and ICENodeOutputPort.

A ICENodePort is a connection point on a ICENode and connects to other ICENodePort objects. ICENodePort may be connected to something or not connected at all. Ports are organized in groups similar to the Softimage operator Port objects where groups are logical groupings of multiple port connections.

bool IsA

(

siClassID

in_ClassID

)

const [virtual]

Returns true if a given class type is compatible with this API class.

Parameters:

in_ClassID

class type.

Returns:

true if the class is compatible, false otherwise.

Reimplemented from SIObject.

Reimplemented in ICENodeInputPort, and ICENodeOutputPort.

siClassID GetClassID

(

)

const [virtual]

Returns the type of the API class.

Returns:

The class type.

Reimplemented from SIObject.

Reimplemented in ICENodeInputPort, and ICENodeOutputPort.

ICENodePort& operator=

(

const ICENodePort &

in_obj

)

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

Parameters:

in_obj

constant class object.

Returns:

The new ICENodePort object.

ICENodePort& operator=

(

const CRef &

in_ref

)

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

Parameters:

in_ref

constant class object.

Returns:

The new ICENodePort object.

Reimplemented from SIObject.

Reimplemented in ICENodeInputPort, and ICENodeOutputPort.

bool IsConnected

(

)

const

Returns a boolean value indicating whether the port is connected (true) or not (false).

Returns:

True if port is connected.

See also:

ICENode::IsConnected

bool IsOutput

(

)

const

Returns a boolean value indicating whether the port direction is output (true) or input (false).

Returns:

The port direction flag.

See also:

ICENodeOutputPort

LONG GetIndex

(

)

const

Returns the index of this port within its port group.

Note:

This property refers to the index of the port within the ICENodePort group. It is different from the index used to access the array of ports returned by ICENode::GetInputPorts, ICENode::GetOutputPorts, and ICENodePort::GetConnectedPorts.

Returns:

The port index.

LONG GetGroupInstanceIndex

(

)

const

Returns the node port group instance that this port belongs to. There may be many objects of the same type connected to the same port group. Each ICENode is connected to a port group instance, and within the port group instance there may be many ports.

Returns:

The port group instance index.

LONG GetGroupIndex

(

)

const

Returns the node port group index to which this port belongs.

Returns:

The port group index.

XSI::siICENodeDataType GetDataType

(

)

const

Returns the data type for this port as an siICENodeDataType value. The returned type identifies the data that can travel through this port.

Returns:

The port data type.

XSI::siICENodeStructureType GetStructureType

(

)

const

Returns the data structure type for this port as an siICENodeStructureType value. The returned type identifies how the data is structured: data can be a single element or an array.

Returns:

The port data structure type.

XSI::siICENodeContextType GetContextType

(

)

const

Returns the context type for this port as an siICENodeContextType value. The returned type identifies the element set associated with the data (cardinality), such as vertices, polygons, or newly created particles.

Returns:

The port evaluation context type.

CRefArray GetConnectedPorts

(

)

const

Returns all the ICENodePort objects connected to this port. ICENodeInputPort objects can only have one connected port; on the other hand, ICENodeOutputPort objects can have multiple ports connected. The returned array is empty if the port is not connected.

Returns:

Array of references to the connected ports.

CRefArray GetConnectedNodes

(

)

const

Returns all the ICENode objects connected to this port. ICENodeInputPort objects can only have one connected node; ICENodeOutputPort objects can have multiple nodes connected.

Returns:

Array of references to the connected ICENode objects.

CRefArray GetParameters

(

)

const

Returns all the Parameter objects defined for this port. For instance, calling ICENodePort::GetParameters on a port which supports the ::siICENodeDataVector3 data type will return an array of 3 parameters: x, y, z. These parameters can then be used for setting keys for instance.

Returns:

Array of references to the parameters for this port.

CStringArray GetCustomDataTypes

(

)

const

Returns an array of custom data types defined for this ICENodePort. Custom data types are defined by custom ICENodes and are used as data type for defining custom ICEPorts and ICEAttributes.

Returns:

Array of custom data type names. Returns an empty array if no custom types are defined on this port.
