Constructor & Destructor Documentation

JGlob() [1/3]

JSYSTEM::JGlob::JGlob ( )

inline

Default constructor.

Definition at line 31 of file JGlob.hh.

    {}

JGlob() [2/3]

JSYSTEM::JGlob::JGlob ( const std::string & pattern )

inline

Constructor.

Parameters

pattern

pattern

Definition at line 40 of file JGlob.hh.

    {
      (*this)(pattern);
    }

JGlob() [3/3]

JSYSTEM::JGlob::JGlob ( const std::vector< std::string > & buffer )

inline

Constructor.

Parameters

buffer

list of patterns

Definition at line 51 of file JGlob.hh.

    {
      (*this)(buffer);
    }

Member Function Documentation

operator()() [1/2]

const JGlob & JSYSTEM::JGlob::operator() ( const std::string & pattern )

inline

Get list of files.

Parameters

pattern

pattern

Returns

list of files

Definition at line 63 of file JGlob.hh.

    {
      this->clear();
 
      evaluate(pattern);
 
      return *this;
    }

operator()() [2/2]

const JGlob & JSYSTEM::JGlob::operator() ( const std::vector< std::string > & buffer )

inline

Get list of files.

Parameters

buffer

list of patterns

Returns

list of files

Definition at line 80 of file JGlob.hh.

    {
      this->clear();
 
      for (const std::string& pattern : buffer) {
        evaluate(pattern);
      }
 
      return *this;
    }

push_back()

void JSYSTEM::JGlob::push_back ( const std::string & file_name )

inline

Push back file.

This method constitutes a light weight wrapper to resolve symbolic links on the fly.

Parameters

file_name

file name

Definition at line 98 of file JGlob.hh.

    {
      static_cast<std::vector<std::string>&>(*this).push_back(resolveSymlink(file_name).string());
    }

evaluate()

void JSYSTEM::JGlob::evaluate ( const std::string & pattern )

inlineprivate

Process pattern.

Parameters

pattern

pattern

Definition at line 109 of file JGlob.hh.

    {
      memset(&buffer, 0, sizeof(buffer));
 
      const int value = glob(pattern.c_str(), GLOB_TILDE | GLOB_BRACE, NULL, &buffer);
 
      if (value == 0) {
 
        for(size_t i = 0; i < buffer.gl_pathc; ++i) {
          this->push_back(buffer.gl_pathv[i]);
        }
 
      } else {
 
        this->push_back(pattern);
      } 
 
      globfree(&buffer);
    }
