class Geo::GeoVariant

Variant class for storing name/value pairs in a map, where the value is a subset of common value types.

The variant is an immutable object, akin to C# style strings.

Classes

Name	Description
Geo::GeoVariant::LinkData	GUID class for representing links.
Geo::GeoVariant::UrlData	String class for representing URLs (e.g. file paths).

Functions

Name	Description
FromStringRepresentation(Type, const char *)	Create a new GeoVariant from the string representation.
GeoVariant(const GeoVariant &)	Copy constructor (we can't use the compiler-generated one as we may need to copy the heap data if this is a Url GeoVariant).

GeoVariant(const LinkData &)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(const UrlData &)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(const Geo::Matrix &)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(const v128 &)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(const GeoString< char > &)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(const char *)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(bool)	Construct a GeoVariant of the given type, with the specified value.
GeoVariant(float)	Construct a GeoVariant of the given type, with the specified value.

GetStringRepresentation()	Convert the value to a string, for use when serialising or presenting in a dialog.
GetType()	Returns the type of this GeoVariant.
Load(IGeoInputStream &)	Binary serialisation functions.
operator!=(const GeoVariant &)	Comparison operators.
operator=(const GeoVariant &)	Assignment.

static GeoVariant Geo::GeoVariant::FromStringRepresentation

public: GeoVariant FromStringRepresentation
(
Type type,
const char * value
)

Create a new GeoVariant from the string representation.

The function requires the type it will create and the new value. The conversion functions are not checked, so failure to convert will result in a GeoVariant of the correct type and a default value.

Geo::GeoVariant::GeoVariant

public: GeoVariant
(
const GeoVariant & rhs
)

Copy constructor (we can't use the compiler-generated one as we may need to copy the heap data if this is a Url GeoVariant).

Geo::GeoVariant::GeoVariant

public: GeoVariant
(
Type t
)

Construct a GeoVariant of a given type, with a default value.
