Member Function Documentation

BdbTime CdbTimeUtils::from_nsec (  unsigned long long    theNumber )  [static]

Translate a 64-bit number of nanoseconds into an object of BdbTime. A number on the input is supposed to be a previously packed value of a BdbTime object. The overflow is returned as BdbTime::plusInfinity Definition at line 133 of file CdbTimeUtils.cc. References BdbTimeConst::nsecInASec, BdbTime::plusInfinity, and BdbTimeConst::plusInfinity. Referenced by CdbMySQLSelectQuery::checked_get(), and CdbMySQLSelectQuery::get().

std::string CdbTimeUtils::get_current_timestamp (    )  [static]

Get the current timestamp. This utility function would produce a string with the current timestamp in the following format: monthDay_hour::minute::sec.milisec Definition at line 112 of file CdbTimeUtils.cc.

bool CdbTimeUtils::string2time (  BdbTime &    theTime, const std::string &    theString )  [static]

Translate a string into an object of BdbTime. A variation of the above explained method. Definition at line 60 of file CdbTimeUtils.cc. References string2time().

bool CdbTimeUtils::string2time (  BdbTime &    theTime, const char *    theString )  [static]

Translate a string into an object of BdbTime. This utility method would attempt to translate the specified string into an object of the BdbTime class if this is possible. A non zero pointer onto a string is expected. NOTE; Unlike the standard method of translating time available through BdbTime::parseTime() the current one will also recognize an internal numeric format of time. If the translation will be successfull then the resulting flag would be set to "true" and the reference would be properly initialized. Otherwise the reference would not be affected. Returns: a boolen flag indicating the result of the translation. Parameters: theTime  the value to be initialized theString  the input string Definition at line 24 of file CdbTimeUtils.cc. References BdbTime::parseTime(). Referenced by main(), CdbBrowserTool::run(), and string2time().

std::string CdbTimeUtils::time2string (  const BdbTime &    theTime, bool    forceInternalFormat = false, bool    packedFormat = false )  [static]

Translate an object of BdbTime into a string. The method would return a string with an internal representation of time: . The only exception of this rule is for the value of BdbTime::minusInfinity and BdbTime::plusInfinity. By default they would be printed as: " -Infinity " " +Infinity " unless an optional flag "forceInternalFormat" is set to "true". By default the resulting string will be of afixed length: 11+1+11=23 characters unless an optional flag "packedFormat" is set to "true". Returns: a string representation of the input object. Parameters: theTime  the input object to be translated forceInternalFormat  the format control flag for "infinity" values packedFormat  the format control flag Definition at line 68 of file CdbTimeUtils.cc.

std::string CdbTimeUtils::time2string2 (  const BdbTime &    theTime, BdbTime::Zone    theTimeZone = BdbTime::Local, bool    forceInternalFormat = false, bool    packedFormat = false )  [static]

Translate an object of BdbTime into a string. The method would return a string with an internal representation of time followed by its human readable string: 3123456789.0987654321 : Wed 15 Jan 2005 10:11:00 (local timezone) 0 ns See also: CdbTimeUtils::time2string() Parameters: theTime  the input object to be translated theTimeZone  the way we're interpreting the time forceInternalFormat  the format control flag for "infinity" values packedFormat  the format control flag Definition at line 95 of file CdbTimeUtils.cc.

unsigned long long CdbTimeUtils::to_nsec (  const BdbTime &    theTime )  [static]

Translate an object of BdbTime class into a 64-bit number of nanoseconds. A number on the input is supposed to be a previously packed value of a BdbTime object.
