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.

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.

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).

public: GeoVariant
(
    Type t
)

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

public: GeoVariant
(
    const LinkData & x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    const UrlData & x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    const Geo::Matrix & x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    const v128 & x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    const GeoString< char > & x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    const char * x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    bool x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    float x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    u64 x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    s64 x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    u32 x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    s32 x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    s16 x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    u16 x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoVariant
(
    GeoGuid x
)

Construct a GeoVariant of the given type, with the specified value.

The various string representations are all internally converted to the utf8 String enum, truncation to 64 characters is silent and will not cause it to fail.

public: GeoString< char > GetStringRepresentation() const

Convert the value to a string, for use when serialising or presenting in a dialog.

public: Type GetType() const

Returns the type of this GeoVariant.

public: bool Load
(
    IGeoInputStream & stream
)

Binary serialisation functions.

public: bool operator!=
(
    const GeoVariant & rhs
) const

Comparison operators.

public: GeoVariant & operator=
(
    const GeoVariant & rhs
)

Assignment.

public: bool operator==
(
    const GeoVariant & rhs
) const

Comparison operators.

public: bool Save
(
    IGeoStream & stream
) const

Binary serialisation functions.

public: bool ToBool() const

Conversion to the underlying type.

Converting a GeoVariant containing type A to a different type will result in a default value. It will not follow C++ conversion rules (so if you ask for an Integer, and it contains a Short, you will get a 0 result).
