Return value |
Content of file. |
bool SaveFile(const char *filename, const String& data)

template <class T> Stream& operator%(Stream& s, T& x)
Serialization operator. Simply invokes x.Serialize(s);
|
T |
Type of variable to be serialized. |
|
x |
Variable to be serialized. |
|
Return value |
s for chaining. |
Stream& operator<<(Stream& s, const char *x)
Overload of stream insertion operator to get simple case work. Insertion operator uses formatted stream output (Putf).
|
x |
Data to write - all characters are written to the stream. |
|
Return value |
s for chaining. |
Stream& operator<<(Stream& s, char *x)
Overload of stream insertion operator to get simple case work. Insertion operator uses formatted stream output (Putf).
|
x |
Data to write - all characters are written to the stream. |
|
Return value |
s for chaining. |
Stream& operator<<(Stream& s, const String &x)
Overload of stream insertion operator to get simple case work. Insertion operator uses formatted stream output (Putf).
|
x |
Data to write - all characters are written to the stream. |
|
Return value |
s for chaining. |
Stream& operator<<(Stream& s, char x)
Overload of stream insertion operator to get simple case work. Insertion operator uses formatted stream output (Putf).
|
x |
Data to write - it is written as single character. |
|
Return value |
s for chaining. |
Stream& operator<<(Stream& s, const void *x)
Overload of stream insertion operator to get simple case work. Insertion operator uses formatted stream output (Putf).
|
x |
Data to write - pointer is formatted as hexadecimal value. |
|
Return value |
s for chaining. |
Stream& operator<<(Stream& s, void *x)
Overload of stream insertion operator to get simple case work. Insertion operator uses formatted stream output (Putf).
|
x |
Data to write - pointer is formatted as hexadecimal value. |
|
Return value |
s for chaining. |
template <class T> Stream& operator<<(Stream& s, const T& x)
Global stream insertion operator. Calls AsString for x and stores the result to the stream. Global AsString version in turn calls ToString method of x.
|
T |
Type of data to write to the stream. |
Return value s for chaining.
