Detailed Description

Interface to iconv.h character-conversion routines.

Constructor & Destructor Documentation

ddcIconv()

ddcIconv::ddcIconv ( const std::string &  srcEncoding = "", const std::string &  dstEncoding = ""  )

inline

Default constructor, given optional source and destination encodings

References PTOP.

~ddcIconv()

ddcIconv::~ddcIconv ( void  )

inline

Default destructor

References PTOP.

Member Function Documentation

empty()

bool ddcIconv::empty ( void  ) const

inline

Check whether selected conversion is a null-op.

valid()

bool ddcIconv::valid ( void  ) const

inline

Check whether selected converter is valid.

good()

bool ddcIconv::good ( void  ) const

inline

Check whether selected converter is a either valid or a null-op

Referenced by CLemmatizer::initIconv().

Here is the caller graph for this function:

open()

bool ddcIconv::open ( const std::string &  srcEncoding, const std::string  dstEncoding  )

inline

Open a (new) encoding. Either srcEncoding or dstEncoding may be empty or "-", indicating a null-op.

References PTOP.

close()

bool ddcIconv::close ( void  )

inline

Close a conversion. Should be ok to call more than once

References PTOP.

reset()

void ddcIconv::reset ( void  )

inline

Reset converter state (should already have mut lock in threaded applications)

convert() [1/3]

bool ddcIconv::convert ( const char *  idata, const size_t  ilen, string &  out  )

inline

Perform selected conversion from in to out (low-level)

References DDC_ICONV_BUFLEN, and PTOP.

Referenced by CQueryTokenNode::BuildRegExp(), CStringIndexSet::QueryTokenListUsingRegExp(), CLemmatizer::recode_ext2int(), and CLemmatizer::recode_int2ext().

Here is the caller graph for this function:

convert() [2/3]

bool ddcIconv::convert ( const string &  in, string &  out  )

inline

Perform selected conversion from in to out

convert() [3/3]

std::string ddcIconv::convert ( const std::string &  in )

inline

Perform selected conversion from in to a (new) string

Member Data Documentation
