Detailed Description

Aliases are compact representations of compound input registrations, combining one or more object accessors with a value specifier into a single input registration.

Function Documentation

AttributeValue() [1/2]

auto AttributeValue ( const TfToken &  attributeName )

inline

See AttributeValue().

AttributeValue() [2/2]

auto AttributeValue

(

const TfToken &

attributeName

)

Input alias that yields the value of the named attribute.

This registration must follow a PrimComputation registration.

‍Note:

AttributeValue<T>(attrToken)

is equivalent to:

Attribute(attrToken)
    .Compute<T>(ExecBuiltinComputations->computeValue)
    .InputName(attrToken)

Example

EXEC_REGISTER_COMPUTATIONS_FOR_SCHEMA(MySchemaType)
{
    // Register a prim computation that returns the computed value of an
    // attribute.
    self.PrimComputation(_tokens->eleven)
        .Callback<double>(+[](const VdfContext &ctx) {
            ctx->SetOutput(ctx.GetInputValue<double>(_tokens->myAttribute));
        })
        .Inputs(
            AttributeValue<double>(_tokens->myAttribute).Required());
}
