UsdShadeOutput#

Fully qualified name: usdrt::UsdShadeOutput

class UsdShadeOutput#

This class encapsulates a shader or node-graph output, which is a connectable attribute representing a typed, externally computed value.

Unnamed Group

inline explicit UsdShadeOutput(const UsdAttribute &attr)#: Speculative constructor that will produce a valid UsdShadeOutput when attr already represents a shade Output, and produces an invalid UsdShadeOutput otherwise (i.e. the explicit bool conversion operator will return false).

inline TfToken GetFullName() const#: Get the name of the attribute associated with the output.

inline TfToken GetBaseName() const#

Returns the name of the output.

We call this the base name since it strips off the “outputs:” namespace prefix from the attribute name, and returns it.

inline SdfValueTypeName GetTypeName() const#: Get the “scene description” value type name of the attribute associated with the output.

inline const UsdAttribute &GetAttr() const#: Explicit UsdAttribute extractor.

inline operator const UsdAttribute&() const#: Allow UsdShadeOutput to auto-convert to UsdAttribute, so you can pass a UsdShadeOutput to any function that accepts a UsdAttribute or const-ref thereto.

inline bool IsDefined() const#: Return true if the wrapped UsdAttribute is defined, and in addition the attribute is identified as an output.

inline explicit operator bool() const#: Return true if this Output is valid for querying and authoring values and metadata, which is identically equivalent to IsDefined().

static inline bool IsOutput(const UsdAttribute &attr)#

Test whether a given UsdAttribute represents a valid Output, which implies that creating a UsdShadeOutput from the attribute will succeed.

Success implies that attr.IsDefined() is true.

Public Functions

UsdShadeOutput() = default#: Default constructor returns an invalid Output. Exists for container classes.

inline bool ConnectToSource(const UsdShadeInput &sourceInput) const#

Connects this Output to the given input, sourceInput.
