const std::string & relativeTo)
{

is.imbue(std::locale::classic());
is.precision(16);
mpIstream = &is;
bool success = true;
bool done = false;
CVersion Version;
CCopasiXMLParser Parser(Version);
#define BUFFER_SIZE 0xfffe

while (!done)
{
mpIstream->get(pBuffer, BUFFER_SIZE, 0);
if (mpIstream->eof()) done = true;
if (mpIstream->fail() && !done)

}示例2: restore
void ParameterizedFunction::restore ( std::istream & is, int format )
{
if (is.good())
{
is.precision (std::numeric_limits<double>::digits10 + 1);
std::string tmp;
bool b_endOfBlock ( false ) ;
while ( !b_endOfBlock )
{

if ( this->isEndTag( tmp, "ParameterizedFunction" ) )
{

{示例3: _GetEpsilon
CoordType _GetEpsilon(std::istream& is)
{
std::streamsize str_prec = is.precision();
CoordType str_eps = 1;
while(--str_prec > 0) // Precision of 6 gives epsilon = 1e-5
str_eps /= 10;
return str_eps;
}示例4: readBranchLength
double readBranchLength(std::istream &iss)
{
auto result = double{0.};
iss.precision(std::numeric_limits<double>::digits10 + 2);
iss >> result;
return result;
