Inheritance diagram for CesiumGltf::ExtensionExtGeospatialCrsWkid:

Public Member Functions
int64_t	getSizeBytes () const
	Calculates the size in bytes of this object, including the contents of all collections, pointers, and strings. This will NOT include the size of any extensions attached to the object. Calling this method may be slow as it requires traversing the object's entire structure.

Public Member Functions inherited from CesiumUtility::ExtensibleObject
template<typename T>
bool	hasExtension () const noexcept
	Checks if an extension exists given its static type.

template<typename T>
const T *	getExtension () const noexcept
	Gets an extension given its static type.

template<typename T>
T *	getExtension () noexcept
	Gets an extension given its static type.

const JsonValue *	getGenericExtension (const std::string &extensionName) const noexcept
	Gets a generic extension with the given name as a CesiumUtility::JsonValue.

JsonValue *	getGenericExtension (const std::string &extensionName) noexcept
	Gets a generic extension with the given name as a CesiumUtility::JsonValue.

template<typename T, typename... ConstructorArgumentTypes>
T &	addExtension (ConstructorArgumentTypes &&... constructorArguments)
	Adds a statically-typed extension to this object.

template<typename T>
void	removeExtension ()
	Removes a statically-typed extension from this object.

int64_t	getSizeBytes () const
	Calculates the size in bytes of this ExtensibleObject, including all of its extras but NOT including its extensions. Calling this method may be slow as it requires traversing the entire object.

Public Attributes
std::string	authority
	The organization that defines and manages a specific CRS identifier.

int64_t	wkid = int64_t()
	An integer that identifies the CRS.

std::optional< int64_t >	vcsWkid
	An integer that identifies the vertical CRS if wkid identifies a horizontal CRS.

std::optional< std::string >	epoch
	An epoch for coordinates that are referenced to a dynamic CRS such as WGS 84. Expressed as a decimal year (e.g. '2019.81').

Public Attributes inherited from CesiumUtility::ExtensibleObject
std::unordered_map< std::string, std::any >	extensions
	The extensions attached to this object.

JsonValue::Object	extras
	Application-specific data.

JsonValue::Object	unknownProperties
	Unknown properties that exist on this object but do not have any representation in the statically-typed classes.

Static Public Attributes
static constexpr const char *	TypeName = "ExtensionExtGeospatialCrsWkid"
	The original name of this type.

static constexpr const char *	ExtensionName = "EXT_geospatial_crs_wkid"
	The official name of the extension. This should be the same as its key in the `extensions` object.
