Detailed Description

Xerces string wrapper.

Xerces uses UTF-16 internally, which is incompatible with the standard library string and stream classes. This class interconverts between std::string and XMLCh *, as well as managing the memory of XMLCh * objects. All Xerces functions and class methods which take XMLCh * inputs may be transparently called with instances of this class, and likewise functions and methods returning XMLCh * may directly construct instances of this class using the return value.

This class does have an overhead of maintaining two copies of the string (char * and XMLCh *), as well as the cost of transcoding between the two forms upon construction.

Assignment of std::string or XMLCh * is not supported. This class is only intended to transiently transcode between the two types and manage the memory for this.

Constructor & Destructor Documentation

ome::common::xml::String::String ( const XMLCh *  str)
inline

Construct a String from an XMLCh * string.

The string content will be copied; no ownership is taken of the original string. The string will also be transcoded to a NUL-terminated char * string.

Parameters
stran XMLCh *string.

References narrow, and wide.

ome::common::xml::String::String ( const char *  str)
inline

Construct a String from a NUL-terminated string.

The string content will be copied into a NUL-terminated char * string. The string will also be transcoded to an XMLCh * string.

Parameters
stra char * NUL-terminated string.

References narrow, and wide.

ome::common::xml::String::String ( std::string const &  str)
inline

Construct a String from a std::string.

The string content will be copied into a NUL-terminated char * string. The string will also be transcoded to an XMLCh * string.

Parameters
stra std::string.

References narrow, and wide.

ome::common::xml::String::~String ( )
inline

Destructor.

The allocated char * and XMLCh * strings will be freed.
