Member Function Documentation

GVariant & GVariant::Cast

(

GVariantType

NewType

)

Changes the variant's type, maintaining the value where possible. If no conversion is available then nothing happens.

References CastDouble(), CastInt32(), CastInt64(), CastString(), Empty(), GV_BOOL, GV_DATETIME, GV_DOUBLE, GV_INT32, GV_INT64, GV_STRING, GDateTime::Set(), Type, and Value.

double GVariant::CastDouble

(

)

Casts the value to double, from whatever source type. The GVariant type does not change after calling this.

References CastDouble(), GV_BOOL, GV_DOMREF, GV_DOUBLE, GV_INT32, GV_INT64, GV_STRING, Type, and Value.

Referenced by Cast(), and CastDouble().

int32 GVariant::CastInt32

(

)

Casts the value to int, from whatever source type. The GVariant type does not change after calling this.

References CastInt32(), GV_BOOL, GV_DOM, GV_DOMREF, GV_DOUBLE, GV_INT32, GV_INT64, GV_STRING, Type, and Value.

Referenced by Cast(), CastInt32(), and GXmlToUi::Convert().

int64 GVariant::CastInt64

(

)

Casts the value to a 64 bit int, from whatever source type. The GVariant type does not change after calling this.

References CastInt64(), GV_BOOL, GV_DOMREF, GV_DOUBLE, GV_INT32, GV_INT64, GV_STRING, Type, and Value.

Referenced by Cast(), and CastInt64().

char * GVariant::CastString

(

)

Cast to a string from whatever source type, the GVariant will take the type GV_STRING after calling this. This is because returning a static string is not thread safe.

References CastString(), GV_BOOL, GV_DATETIME, GV_DOMREF, GV_DOUBLE, GV_INT32, GV_INT64, GV_STRING, Str(), Type, and Value.

Referenced by Cast(), and CastString().

char * GVariant::ReleaseStr

(

)

Returns the string, releasing ownership of the memory to caller and changing this GVariant to GV_NULL.

References GV_NULL, Str(), Type, and Value.

char16 * GVariant::ReleaseWStr

(

)

Returns the wide string, releasing ownership of the memory to caller and changing this GVariant to GV_NULL.

References GV_NULL, Type, Value, and WStr().
