Detailed Description

A base class for binary operation

  • arithmetic operations: + - / * % << >> & | ||
  • relational operations: = (or ==) < > <= >= <> (or !=) LIKE IN 'SIMILAR TO' 'NOT SIMILAR TO'
  • logical operations: OR (or ||) AND (or &&) XOR
  • SpecialBinary "pseudo operators": e.g. "f1 f2" : token == 0 e.g. "f1 AS f2" : token == AS

Constructor & Destructor Documentation

◆ BinaryExpr() [1/2]

BinaryExpr::BinaryExpr ( int  aClass,
BaseExpr *  left_expr,
int  token,
BaseExpr *  right_expr 
)

Definition at line 328 of file expression.cpp.

◆ BinaryExpr() [2/2]

BinaryExpr::BinaryExpr ( const BinaryExpr &  expr)

Definition at line 340 of file expression.cpp.

◆ ~BinaryExpr()

BinaryExpr::~BinaryExpr ( )
virtual

Definition at line 347 of file expression.cpp.

Member Function Documentation

◆ copy()

BinaryExpr * BinaryExpr::copy ( ) const
virtual
Returns
a deep copy of this object.

Implements KexiDB::BaseExpr.

Definition at line 353 of file expression.cpp.

◆ debugString()

TQString BinaryExpr::debugString ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 411 of file expression.cpp.

◆ getQueryParameters()

void BinaryExpr::getQueryParameters ( QuerySchemaParameterList &  params)
virtual

Collects query parameters (messages and types) reculsively and saves them to params. The leaf nodes are objects of QueryParameterExpr class.

Implements KexiDB::BaseExpr.

Definition at line 458 of file expression.cpp.

◆ left()

BaseExpr * KexiDB::BinaryExpr::left ( ) const
inline

Definition at line 187 of file expression.h.

◆ right()

BaseExpr * KexiDB::BinaryExpr::right ( ) const
inline

Definition at line 188 of file expression.h.

◆ tokenToString()

TQString BinaryExpr::tokenToString ( )
virtual
Returns
string for token, like "<=" or ">"

Reimplemented from KexiDB::BaseExpr.

Definition at line 421 of file expression.cpp.

◆ toString()

TQString BinaryExpr::toString ( QuerySchemaParameterValueListIterator *  params = 0)
virtual
Returns
string as a representation of this expression element by running recursive calls. param, if not 0, points to a list item containing value of a query parameter (used in QueryParameterExpr).

Implements KexiDB::BaseExpr.

Definition at line 451 of file expression.cpp.

◆ type()

Field::Type BinaryExpr::type ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 381 of file expression.cpp.

◆ validate()

bool BinaryExpr::validate ( ParseInfo &  parseInfo)
virtual
Todo:
compare types..., BITWISE_SHIFT_RIGHT requires integers, etc...

Reimplemented from KexiDB::BaseExpr.

Definition at line 358 of file expression.cpp.
