Field Access Methods | |
These methods help get values for additional fields defined on a attribute in a prim definition. None of the data access methods check that the attribute is valid before trying to access the attribute. I.e. they all assume the attribute is already known to be valid when called. Client code is on the hook for verifying the validity of the Attribute before calling any of these methods. The validity can be determined by converting the Attribute to bool. | |

Accessor to a attribute's definition in the prim definition.
These are returned by calls to UsdPrimDefinition::GetAttributeDefinition and can be freely converted to from a Property accessor. These can be used to check that a property exists and is an attribute (via conversion to bool) and to get attribute relevant field values that are defined for a property in the prim definition.
This class is just a thin wrapper around the property representation in the UsdPrimDefinition that creates it and cannot be stored or accessed beyond the lifetime of the prim definition itself.

default |
Default constructor returns an invalid attribute.
Copy constructor from a Property to allow implicit conversion.
Move constructor from a Property to allow implicit conversion.
| bool UsdPrimDefinition::Attribute::GetFallbackValue | ( | T * | value | ) | const |
Retrieves the fallback value of type T for this attribute and stores it in value if possible.
Returns true if this attribute has a fallback value defined with the expected type. Returns false otherwise.
Definition at line 653 of file primDefinition.h.
| USD_API SdfValueTypeName UsdPrimDefinition::Attribute::GetTypeName | ( | ) | const |
Returns the value type name of this attribute in the prim definition.
Returns the token value of the type name of this attribute in the prim definition.
|
inlineexplicit |
Conversion to bool returns true if this represents a valid property in the prim definition that is an attribute, and false otherwise.
