Function Documentation

SDR_API std::string ShaderMetadataHelpers::CreateStringFromStringVec

(

const NdrStringVec &

stringVec

)

Serializes a vector of strings into a string using the pipe character as the delimiter.

SDR_API TfToken ShaderMetadataHelpers::GetRoleFromMetadata

(

const NdrTokenMap &

metadata

)

Gets the "role" from metadata if one is provided. Only returns a value.

SDR_API int ShaderMetadataHelpers::IntVal	(	const TfToken &	key,
		const NdrTokenMap &	metadata,
		int	defaultValue = std::numeric_limits< int >::max()
	)

Extracts the int value from the given metadatum if it exists and is a valid integer value, otherwise returns default value.

SDR_API bool ShaderMetadataHelpers::IsPropertyAnAssetIdentifier

(

const NdrTokenMap &

metadata

)

Determines if the specified property metadata has a widget that indicates the property is an asset identifier.

SDR_API bool ShaderMetadataHelpers::IsPropertyATerminal

(

const NdrTokenMap &

metadata

)

Determines if the specified property metadata has a 'renderType' that indicates the property should be a SdrPropertyTypes->Terminal

SDR_API bool ShaderMetadataHelpers::IsTruthy	(	const TfToken &	key,
		const NdrTokenMap &	metadata
	)

Determines if the given metadatum in the metadata dictionary has a truthy value. All values are considered to be true except the following (case-insensitive): '0', 'false', and 'f'. The absence of key in the metadata also evaluates to false.

SDR_API NdrOptionVec ShaderMetadataHelpers::OptionVecVal

(

const std::string &

optionStr

)

Extracts an "options" vector from the given string.

SDR_API std::string ShaderMetadataHelpers::StringVal	(	const TfToken &	key,
		const NdrTokenMap &	metadata,
		const std::string &	defaultValue = std::string()
	)

Extracts the string value from the given metadatum if it exists, otherwise returns defaultValue.

SDR_API NdrStringVec ShaderMetadataHelpers::StringVecVal	(	const TfToken &	key,
		const NdrTokenMap &	metadata
	)

Extracts a vector of strings from the given metadatum. An empty vector is returned if the metadatum does not exist.

SDR_API TfToken ShaderMetadataHelpers::TokenVal	(	const TfToken &	key,
		const NdrTokenMap &	metadata,
		const TfToken &	defaultValue = TfToken()
	)

Extracts the tokenized value from the given metadatum if it exists, otherwise returns defaultValue.

SDR_API NdrTokenVec ShaderMetadataHelpers::TokenVecVal	(	const TfToken &	key,
		const NdrTokenMap &	metadata
	)

Extracts a vector of tokenized values from the given metadatum. An empty vector is returned if the metadatum does not exist.
