Detailed Description

Houdini API schema for marking primitives as selectable or not.

Definition at line 57 of file houdiniSelectableAPI.h.

Constructor & Destructor Documentation

UsdHoudiniHoudiniSelectableAPI::UsdHoudiniHoudiniSelectableAPI ( const UsdPrim prim = UsdPrim())
inlineexplicit

Construct a UsdHoudiniHoudiniSelectableAPI on UsdPrim prim . Equivalent to UsdHoudiniHoudiniSelectableAPI::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 71 of file houdiniSelectableAPI.h.

UsdHoudiniHoudiniSelectableAPI::UsdHoudiniHoudiniSelectableAPI ( const UsdSchemaBase schemaObj)
inlineexplicit

Construct a UsdHoudiniHoudiniSelectableAPI on the prim held by schemaObj . Should be preferred over UsdHoudiniHoudiniSelectableAPI(schemaObj.GetPrim()), as it preserves SchemaBase state.

Definition at line 79 of file houdiniSelectableAPI.h.

virtual UsdHoudiniHoudiniSelectableAPI::~UsdHoudiniHoudiniSelectableAPI ( )

Destructor.

Member Function Documentation

UsdSchemaKind UsdHoudiniHoudiniSelectableAPI::_GetSchemaKind ( ) const
overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind

Reimplemented from UsdSchemaBase.

static UsdHoudiniHoudiniSelectableAPI UsdHoudiniHoudiniSelectableAPI::Apply ( const UsdPrim prim)
static

Applies this single-apply API schema to the given prim. This information is stored by adding "HoudiniSelectableAPI" to the token-valued, listOp metadata apiSchemas on the prim.

Returns
A valid UsdHoudiniHoudiniSelectableAPI object is returned upon success. An invalid (or empty) UsdHoudiniHoudiniSelectableAPI object is returned upon failure. See UsdPrim::ApplyAPI() for conditions resulting in failure.

UsdPrim::ApplyAPI()
UsdPrim::RemoveAPI()
static bool UsdHoudiniHoudiniSelectableAPI::CanApply ( const UsdPrim prim,
std::string whyNot = nullptr 
)
static

Returns true if this single-apply API schema can be applied to the given prim. If this schema can not be a applied to the prim, this returns false and, if provided, populates whyNot with the reason it can not be applied.

Note that if CanApply returns false, that does not necessarily imply that calling Apply will fail. Callers are expected to call CanApply before calling Apply if they want to ensure that it is valid to apply a schema.

UsdAttribute UsdHoudiniHoudiniSelectableAPI::CreateHoudiniSelectableAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetHoudiniSelectableAttr(), and also Usd_Create_Or_Get_Property for when to use Get vs Create. If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

static UsdHoudiniHoudiniSelectableAPI UsdHoudiniHoudiniSelectableAPI::Get ( const UsdStagePtr &  stage,
const SdfPath path 
)
static

Return a UsdHoudiniHoudiniSelectableAPI holding the prim adhering to this schema at path on stage. If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

UsdHoudiniHoudiniSelectableAPI(stage->GetPrimAtPath(path));
UsdAttribute UsdHoudiniHoudiniSelectableAPI::GetHoudiniSelectableAttr ( ) const

If true, then this primitive will be selectable in the Houdini viewport. If false, clicking on this primitive in the viewport will select nothing. This attribute can be set at any level of the scene graph hierarchy, and its effect will apply to all descendant primitives. If values are authored at multiple levels of the scene graph tree, the value on the primitive or ancestor closest to the primitive that was clicked on will determine if the primitive can be selected or not.

Declaration uniform bool houdini:selectable = 1
C++ Type bool
Usd Type SdfValueTypeNames->Bool
Variability SdfVariabilityUniform
static const TfTokenVector& UsdHoudiniHoudiniSelectableAPI::GetSchemaAttributeNames ( bool  includeInherited = true)
static

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes. Does not include attributes that may be authored by custom/extended methods of the schemas involved.
