#include <wx/buffer.h>
Inheritance diagram for wxCharTypeBuffer< T >:wxCharTypeBuffer<T> is a template class for storing characters.
The difference from wxScopedCharTypeBuffer<T> is that this class doesn't have non-owned mode and the data stored in it are valid for as long as the buffer instance exists. Other than that, this class' behaviour is the same as wxScopedCharTypeBuffer<T>'s – in particular, the data are reference-counted and copying the buffer is cheap.
wxScopedCharTypeBuffer<T> buffers can be converted into wxCharTypeBuffer<T>.
| T | The type of the characters stored in this class. |

Static Public Member Functions inherited from wxScopedCharTypeBuffer< T > | |
| static const wxScopedCharTypeBuffer | CreateNonOwned (const CharType *str, size_t len=wxNO_LEN) |
| Creates non-owned buffer from string data str. More... | |
| static const wxScopedCharTypeBuffer | CreateOwned (CharType *str, size_t len=wxNO_LEN) |
| Creates owned buffer from str and takes ownership of it. More... | |
| wxCharTypeBuffer< T >::wxCharTypeBuffer | ( | const CharType * | str = NULL, |
| size_t | len = wxNO_LEN |
||
| ) |
Creates (owned) buffer from str and takes ownership of it.
| str | String data. |
| len | If specified, length of the string, otherwise the string is considered to be NUL-terminated. |
| wxCharTypeBuffer< T >::wxCharTypeBuffer | ( | size_t | len | ) |
Creates (owned) buffer of size len.
| wxCharTypeBuffer< T >::wxCharTypeBuffer | ( | const wxCharTypeBuffer< T > & | src | ) |
Copy constructor.
Increases reference count on the data, does not make wxStrdup() copy of the data.
| wxCharTypeBuffer< T >::wxCharTypeBuffer | ( | const wxScopedCharTypeBuffer< T > & | src | ) |
Makes a copy of scoped buffer src.
If src is a non-owned buffer, a copy of its data is made using wxStrdup(). If src is an owned buffer, this constructor behaves in the usual way (reference count on buffer data is incremented).
| bool wxCharTypeBuffer< T >::extend | ( | size_t | len | ) |
Extends the buffer to have size len.
Can only be called on buffers that don't share data with another buffer (i.e. reference count of the data is 1).
| wxCharTypeBuffer& wxCharTypeBuffer< T >::operator= | ( | const CharType * | str | ) |
Assigns str to this buffer and takes ownership of it (i.e. the buffer becomes "owned").
| wxCharTypeBuffer& wxCharTypeBuffer< T >::operator= | ( | const wxCharTypeBuffer< T > & | src | ) |
Assignment operator behaves in the same way as the copy constructor.
| wxCharTypeBuffer& wxCharTypeBuffer< T >::operator= | ( | const wxScopedCharTypeBuffer< T > & | src | ) |
Assigns a scoped buffer to this buffer.
If src is a non-owned buffer, a copy of its data is made using wxStrdup(). If src is an owned buffer, the assignment behaves in the usual way (reference count on buffer data is incremented).
| bool wxCharTypeBuffer< T >::shrink | ( | size_t | len | ) |
Shrinks the buffer to have size len and NUL-terminates the string at this length.
Can only be called on buffers that don't share data with another buffer (i.e. reference count of the data is 1).
| len | Length to shrink to. Must not be larger than current length. |
