Class Description

The ProjectItem class represents the base content class in Softimage from which all other content objects derive. Its major feature is that it provides access to the parameters which represent the state of the object.

Many classes in Softimage support this interface, such as X3DObject, Property, Shader, Operator, and Primitive. The classes that do not support this are lightweight classes like Particle, Point, Geometry and Parameter, utility classes such as CValue, CColor, CGraphicSequencer or classes that are not content-related such as Command, Application and UIToolkit.

Member Function Documentation

ProjectItem& operator= ( const ProjectItem 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 ProjectItem object.
CString GetFamilies ( ) const

Returns the names of all the families the object belongs to.

Returns:
String representing all families to which this object belongs.
siCapabilities GetCapabilities ( ) const

Returns a mask of all the object's capabilities.

Returns:
The object's capabilities.
CStatus PutCapabilityFlag ( siCapabilities  in_flag,
bool  in_bEnable 
)

Disables or enables any Capability flag set on the object. For example an object can be hidden from the Scene Explorer by setting the siNotInspectable flag. Changing the capability flags only affects one particular instance of the object.

Parameters:
in_flag Specify the flag to change
in_bEnable True to set the capability; false to remove it.
See also:
Parameter::GetCapabilities
Since:
5.1
bool GetSelected ( siBranchFlag  in_branchFlag = siNode ) const

Returns the object's selected state.

Parameters:
in_branchFlag Is the object selected in node or branch? the default value is siNode. This argument only applies to objects that have children such as the X3DObject and Model objects.
Returns:
true if the current object is selected.
CStatus PutSelected ( bool  in_newState,
siBranchFlag  in_branchFlag = siNode 
)

Sets the object's selected state.

Parameters:
in_newState new state
in_branchFlag Is the object to be selected in node or branch? the default value is siNode. This argument only applies to objects that have children such as the X3DObject and Model objects.
Returns:
CStatus::OK success
CStatus::Fail other failure
CRefArray GetOwners ( ) const

Returns an array of references to all owners of this object. If this function is called from the Update context of a custom operator it returns an empty CRefArray.

Returns:
Array of references to owners.
CParameterRefArray& GetParameters ( ) const

Returns an array of references to all parameters within the object that support read access; that is, you can get their value using Parameter::GetValue.

Note:
This function builds a cache of all parameters. Building the cache can be costly performance wise. Use this function in cases where the object has many parameters and you need to access most of them. It is more suitable to use GetParameter if you only need to access a few parameters.
Returns:
Array of Parameter objects
See also:
ProjectItem::GetParameter, Parameter::GetParameter
Returns:
Array of references to parameters.
Model GetModel ( ) const

Returns the Model to which the object belongs. If this method is called from the Update context of a custom operator it returns an invalid Model.

Returns:
The Model to which this object belongs.
bool IsRelationship ( siPSetRelationship  in_PSetRelationship ) const

Returns true if the object has the required kind of parent/child parameter-set (Pset) relationship with its parent and false otherwise

Note:
Prior to v5.0 this was called IsA(). This conflicted with the other IsA() method for testing the class id. This function maps to ProjectItem.IsA in the scripting object model.
Parameters:
in_PSetRelationship Type of Pset relationship to check.
Returns:
true if the object has the specified type of Pset relationship with its parent; otherwise false.
Since:
5.0
bool BelongsTo ( const CString in_family ) const

Returns true if the object belongs to specified family and false otherwise.

Parameters:
in_family Family (or families) to check
Returns:
true if the object belongs to the specified family; otherwise false.
See also:
siFamily

Returns true if this object matches a given type and false otherwise.

Parameters:
in_objectType an object type.
Returns:
true if this object matches a given type; otherwise false.
bool IsAnimated ( siSourceType  in_sourceType = siAnySource,
bool  in_bLocal = false 
) const

Returns true if the object is animated by a specific animation source type and false otherwise.

Parameters:
in_sourceType Animation source type. The default value is any source.
in_bLocal Specifies whether the animation to check is local to the object or not. If true then all animated parameters that come from propagated properties or from intermediate nodes are ignored. Intermediate nodes are nested under the object but are not necessary owned by the object itself. For instance, the camera object nested under a Texture_Projection_Def property is not considered unless the target object is the projection property itself. When the flag is set to false (default), all parameters are considered.
Returns:
true if the object is animated; false otherwise.
CRefArray GetAnimatedParameters ( siSourceType  in_sourceType = siAnySource,
bool  in_bLocal = false 
) const

Returns an array of references to parameters that are animated by a specific animation source type. If this method is called from the Update() context of a custom operator it will return an empty CRefArray.

Parameters:
in_sourceType an object type.
in_bLocal Specifies whether the animation to check is local to the object or not. If true then all animated parameters that come from propagated properties or from intermediate nodes are ignored. Intermediate nodes are nested under the object but are not necessary owned by the object itself. For instance, the camera object nested under a Texture_Projection_Def property is not considered unless the target object is the projection property itself. When the flag is set to false (default), all parameters are considered.
Returns:
Array of references to Parameter objects.
CRef EvaluateAt ( double  in_dFrame = DBL_MAX )

Returns:
Reference to the object.
CStatus PutParameterValue ( const CString in_scriptname,
bool  in_val,
double  in_time = DBL_MAX 
)

ICEAttribute AddICEAttribute ( const CString in_name,
XSI::siICENodeDataType  in_DataType,
XSI::siICENodeStructureType  in_StructureType,
XSI::siICENodeContextType  in_ContextType 
)

Adds and returns a new ICEAttribute on this object. If the attribute already exists, the current attribute is returned.

Parameters:
in_name Name of the attribute to create.
in_DataType The attribute data type.
in_StructureType The attribute structure type.
in_ContextType The attribute context type.
Returns:
The newly created ICEAttribute object or the existing attribute if already defined.

CStatus RemoveICEAttribute ( const CString in_name )

Removes the attribute identified with in_name from this object. The attribute is removed only if it is not a built-in attribute or not required by an ICETree.

Parameters:
in_name Name of the attribute to remove.
Returns:
CStatus::OK success
CStatus::False the attribute doesn't exist
CStatus::Fail failure

LONG GetEvaluationID ( )

Returns the last evaluation ID. The evaluation ID is a counter that is incremented each time the ProjectItem is evaluated (dirtied) by XSI. You can use this to detect whether a ProjectItem became dirty since the last time GetEvaluationID was called.

Return values:
The evaluation ID (LONG)
Returns:
-1 on failure
Since:
9.0 (2011)
LONG GetHierarchicalEvaluationID ( )

Returns the sum of the evaluation ID for the hierarchy of object that are nested under this object. This is equivalent to doing the sum manually of all EvaluationID for the object.

Return values:
The evaluation ID (LONG)
Returns:
-1 on failure
Since:
9.0 (2011)
