-
__construct() public
Constructor
-
_bindValue() protected
Registers a value in the placeholder generator and returns the generated placeholder
-
_castToExpression() protected
Conditionally converts the passed value to an ExpressionInterface object if the type class implements the ExpressionTypeInterface. Otherwise, returns the value unmodified.
-
_requiresToExpressionCasting() protected
Returns an array with the types that require values to be casted to expressions, out of the list of type names passed as parameter.
-
getField() public
Returns the field name
-
setField() public
Sets the field name
-
sql() public
Converts the Node into a SQL string fragment.
-
traverse() public
Iterates over each part of the expression recursively for every level of the expressions tree and executes the $callback callable passing as first parameter the instance of the expression currently being iterated.
