Base class for UsdAttribute and UsdRelationship scenegraph objects.
UsdProperty has a bool conversion operator that validates that the property IsDefined() and thus valid for querying and authoring values and metadata. This is a fairly expensive query that we do not cache, so if client code retains UsdProperty objects it should manage its object validity closely for performance. An ideal pattern is to listen for UsdNotice::StageContentsChanged notifications, and revalidate/refetch retained UsdObjects only then and otherwise use them without validity checking.

Flattens this property to a property spec with the same name beneath the given parent prim in the edit target of its owning stage.
The parent prim may belong to a different stage than this property's owning stage.
Flattening authors all authored resolved values and metadata for this property into the destination property spec. If this property is a builtin property, fallback values and metadata will also be authored if the destination property has a different fallback value or no fallback value, or if the destination property has an authored value that overrides its fallback.
Attribute connections and relationship targets that target an object beneath this property's owning prim will be remapped to target objects beneath the destination parent prim.
If the destination spec already exists, it will be overwritten.

Flattens this property to a property spec with the same name beneath the given parent prim in the edit target of its owning stage.
The parent prim may belong to a different stage than this property's owning stage.
Flattening authors all authored resolved values and metadata for this property into the destination property spec. If this property is a builtin property, fallback values and metadata will also be authored if the destination property has a different fallback value or no fallback value, or if the destination property has an authored value that overrides its fallback.

| USD_API bool UsdProperty::ClearDisplayGroup | ( | ) | const |
Clears this property's display group (metadata) in the current EditTarget (only). Returns true on success.
| USD_API UsdProperty UsdProperty::FlattenTo | ( | const UsdPrim & | parent | ) | const |
Flattens this property to a property spec with the same name beneath the given parent prim in the edit target of its owning stage.
The parent prim may belong to a different stage than this property's owning stage.
Flattening authors all authored resolved values and metadata for this property into the destination property spec. If this property is a builtin property, fallback values and metadata will also be authored if the destination property has a different fallback value or no fallback value, or if the destination property has an authored value that overrides its fallback.
Attribute connections and relationship targets that target an object beneath this property's owning prim will be remapped to target objects beneath the destination parent prim.
If the destination spec already exists, it will be overwritten.
| USD_API UsdProperty UsdProperty::FlattenTo | ( | const UsdPrim & | parent, |
| const TfToken & | propName | ||
| ) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Flattens this property to a property spec with the given propName beneath the given parent prim in the edit target of its owning stage.
The parent prim may belong to a different stage than this property's owning stage.
| USD_API UsdProperty UsdProperty::FlattenTo | ( | const UsdProperty & | property | ) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Flattens this property to a property spec for the given property in the edit target of its owning prim's stage.
The property owning prim may belong to a different stage than this property's owning stage.
Return this property's name with all namespace prefixes removed, i.e. the last component of the return value of GetName()
This is generally the property's "client name"; property namespaces are often used to group related properties together. The namespace prefixes the property name but many consumers will care only about un-namespaced name, i.e. its BaseName. For more information, see Usd_Ordering
| USD_API std::string UsdProperty::GetDisplayGroup | ( | ) | const |
Return this property's display group (metadata). This returns the empty token if no display group has been set.
Return this property's complete namespace prefix. Return the empty token if this property has no namespaces.
This is the complement of GetBaseName(), although it does not contain a trailing namespace delimiter
| USD_API std::vector<std::string> UsdProperty::GetNestedDisplayGroups | ( | ) | const |
Return this property's displayGroup as a sequence of groups to be nested, or an empty vector if displayGroup is empty or not authored.
| USD_API SdfPropertySpecHandleVector UsdProperty::GetPropertyStack | ( | UsdTimeCode | time = UsdTimeCode::Default() | ) | const |
Returns a strength-ordered list of property specs that provide opinions for this property.
If time is UsdTimeCode::Default(), or this property is a UsdRelationship (which are never affected by clips), we will not consider value clips for opinions. For any other time, for a UsdAttribute, clips whose samples may contribute an opinion will be included. These specs are ordered from strongest to weakest opinion, although if time requires interpolation between two adjacent clips, both clips will appear, sequentially.
UsdAttributeQuery .| USD_API std::vector<std::pair<SdfPropertySpecHandle, SdfLayerOffset> > UsdProperty::GetPropertyStackWithLayerOffsets | ( | UsdTimeCode | time = UsdTimeCode::Default() | ) | const |
Returns a strength-ordered list of property specs that provide opinions for this property paired with the cumulative layer offset from the stage's root layer to the layer containing the property spec.
This behaves exactly the same as UsdProperty::GetPropertyStack with the addition of providing the cumulative layer offset of each spec's layer.
UsdAttributeQuery . | USD_API bool UsdProperty::HasAuthoredDisplayGroup | ( | ) | const |
Returns true if displayGroup was explicitly authored and GetMetadata() will return a meaningful value for displayGroup.
| USD_API bool UsdProperty::IsAuthored | ( | ) | const |
Return true if there are any authored opinions for this property in any layer that contributes to this stage, false otherwise.
| USD_API bool UsdProperty::IsAuthoredAt | ( | const class UsdEditTarget & | editTarget | ) | const |
Return true if there is an SdfPropertySpec authored for this property at the given editTarget, otherwise return false. Note that this method does not do partial composition. It does not consider whether authored scene description exists at editTarget or weaker, only exactly at the given editTarget.
| USD_API bool UsdProperty::IsCustom | ( | ) | const |
Return true if this is a custom property (i.e., not part of a prim schema).
The 'custom' modifier in USD serves the same function as Alembic's 'userProperties', which is to say as a categorization for ad hoc client data not formalized into any schema, and therefore not carrying an expectation of specific processing by consuming applications.
| USD_API bool UsdProperty::IsDefined | ( | ) | const |
Return true if this is a builtin property or if the strongest authored SdfPropertySpec for this property's path matches this property's dynamic type. That is, SdfRelationshipSpec in case this is a UsdRelationship, and SdfAttributeSpec in case this is a UsdAttribute. Return false if this property's prim has expired.
For attributes, a true return does not imply that this attribute possesses a value, only that has been declared, is of a certain type and variability, and that it is safe to use to query and author values and metadata.
| USD_API bool UsdProperty::SetCustom | ( | bool | isCustom | ) | const |
Set the value for custom at the current EditTarget, return true on success, false if the value can not be written.
Note that this value should not be changed as it is typically either automatically authored or provided by a property definition. This method is provided primarily for fixing invalid scene description.
| USD_API bool UsdProperty::SetDisplayGroup | ( | const std::string & | displayGroup | ) | const |
Sets this property's display group (metadata). Returns true on success.
DisplayGroup provides UI hinting for grouping related properties together for display. We define a convention for specifying nesting of groups by recognizing the property namespace separator in displayGroup as denoting group-nesting.
| USD_API bool UsdProperty::SetNestedDisplayGroups | ( | const std::vector< std::string > & | nestedGroups | ) | const |
Sets this property's display group (metadata) to the nested sequence. Returns true on success.
A displayGroup set with this method can still be retrieved with GetDisplayGroup(), with the namespace separator embedded in the result. If nestedGroups is empty, we author an empty string for displayGroup.
| USD_API std::vector<std::string> UsdProperty::SplitName | ( | ) | const |
Return this property's name elements including namespaces and its base name as the final element.
