Member Function Documentation

virtual mpcl::text::TString uesqlc::IType::get (  void    )  const [pure virtual]

Returns a string with the value of the instance. If the instance holds a null value, then the string 'NULL' will be printed. Returns: The result of converting this instance to string. Implemented in uesqlc::TDate, uesqlc::TIdentifier, uesqlc::TInteger, uesqlc::TReal, uesqlc::TSearchCondition, uesqlc::TString, and uesqlc::TTime. Referenced by uesqlc::TAbstractConnectionManager< TConnectionData, TResult >::pushOnInputQueue().

void* uesqlc::IType::getBuffer (  const size_type    kzSIZE )  const [inline]

Returns a buffer where you can assign a value of, at most, kzSIZE octets. Parameters: kzSIZE  Octet count. Returns: A pointer to the buffer. Definition at line 141 of file type.hh. References size_type.

bool uesqlc::IType::isNull (  void    )  const [inline]

Returns true if the last data retrieved has been a NULL value. Returns: True if the last data retrieved has been a NULL value. Definition at line 155 of file type.hh. Referenced by uesqlc::TTime::get(), uesqlc::TString::get(), uesqlc::TSearchCondition::get(), uesqlc::TReal::get(), uesqlc::TInteger::get(), uesqlc::TIdentifier::get(), uesqlc::TDate::get(), uesqlc::TTime::set(), uesqlc::TReal::set(), uesqlc::TInteger::set(), and uesqlc::TDate::set().

virtual void uesqlc::IType::set (  const string &    rkyVALUE )  [pure virtual]

Assigns value rkyVALUE. Parameters: rkyVALUE  Source value. Implemented in uesqlc::TDate.

virtual void uesqlc::IType::set (  const char *    pkcVALUE )  [pure virtual]

Assigns value pkcVALUE. Parameters: pkcVALUE  Source value. Implemented in uesqlc::TDate, uesqlc::TInteger, uesqlc::TReal, uesqlc::TSearchCondition, uesqlc::TString, and uesqlc::TTime. Referenced by updateFromBuffer().

void uesqlc::IType::setNull (  bool    gIS_NULL )  [inline, protected]

Sets null state of the instance. Parameters: gIS_NULL  Null state. Definition at line 69 of file type.hh. Referenced by uesqlc::TTime::set(), uesqlc::TString::set(), uesqlc::TSearchCondition::set(), uesqlc::TReal::set(), uesqlc::TInteger::set(), uesqlc::TDate::set(), uesqlc::TDate::TDate(), uesqlc::TInteger::TInteger(), uesqlc::TReal::TReal(), uesqlc::TString::TString(), and uesqlc::TTime::TTime().

void uesqlc::IType::updateFromBuffer (  void    )  [inline]

Returns a buffer where you can assign a value of, at most, kzSIZE octets. Parameters: kzSIZE  Octet count. Returns: A pointer to the buffer. Definition at line 101 of file type.hh. References set().
