Tracks data and its type for saving and restoring unknown
ENTITY types.

Description:
|
This class reads in data from unknown
ENTITY types. It stores the data and its type so that it can be written back out in binary mode.
|
|
|
Data:
|
public DataType m_dataType;
|
|
The type of data.
|
|
|
public enum DataType;
|
|
The values of the items in this enumeration are written to a binary save file to identify the type of data items in an unknown
ENTITY. Because these values are used when restoring unknown
ENTITY data, they are given explicitly and must not be changed.

|
|
|
);
|
|
|
C++ constructor, creating a
TaggedData using the specified parameters.
|
|
|

|
|
|
public: TaggedData::TaggedData
(
|
|
|
double
|
// double value

|
|
|
|
|
|
public: TaggedData::TaggedData
(
|
|
|
float
|
// float value
|
|
|
);
|
|
|
C++ constructor, creating a
TaggedData using a floating value.
|
|
|
|
|
|
|
public: TaggedData::TaggedData

Destructor:
|
public: TaggedData::~TaggedData
();
|
|
|
