CFixedStringT Class
This class represents a string object with a fixed character buffer.
template< class StringType, int t_nChars >
class CFixedStringT : private CFixedStringMgr, public StringType
Parameters
StringType
Used as the base class for the fixed string object and can be any CStringT-based type. Some examples include CString, CStringA, and CStringW.t_nChars
The number of characters stored in the buffer.
Remarks
This class is an example of a custom string class based on CStringT. Although quite similar, the two classes differ in implementation. The major differences between CFixedStringT and CStringT are:
The initial character buffer is allocated as part of the object and has size t_nChars. This allows the CFixedString object to occupy a contiguous memory chunk for performance purposes. However, if the contents of a CFixedStringT object grows beyond t_nChars, the buffer is allocated dynamically.
The character buffer for a CFixedStringT object is always the same length (t_nChars). There is no limitation on buffer size for CStringT objects.
The memory manager for CFixedStringT is customized such that sharing of a CStringData object between two or more CFixedStringT objectsis not allowed. CStringT objects do not have this limitation.
For more information on the customization of CFixedStringT and memory management for string objects in general, see Memory Management and CStringT.
