The UValue contains an UDataType which can take the values: DATA_DOUBLE, DATA_STRING, DATA_BINARY, DATA_LIST, DATA_OBJECT, DATA_VOID. Depending of this field, the corresponding value in the UValue will be set. If the UValue is of binary type, it contains an UBinary class defined hereafter. The UBinaryType in the UBinary structure will give additional informations on the type of data (BINARY_NONE, BINARY_UNKNOWN, BINARY_IMAGE, BINARY_SOUND), and the appropriate sound or image structure will be filled.
