public &ConditionInterface::conditions() Gets a complete list of all conditions in this conditional clause. This method returns by reference. That allows alter hooks to access the data structure directly and manipulate it before it gets compiled. The data structure that is returned is an indexed array of entries, where each entry looks like the following: array( 'field' => $field, 'value' => $value, 'operator' => $operator, ); In the special case that $operator is NULL, the

public ConditionInterface::conditionGroupFactory($conjunction = 'AND') Creates an object holding a group of conditions. See andConditionGroup() and orConditionGroup() for more.

public ConditionInterface::condition($field, $value = NULL, $operator = '=') Helper function: builds the most common conditional clauses. This method can take a variable number of parameters. If called with two parameters, they are taken as $field and $value with $operator having a value of =. Do not use this method to test for NULL values. Instead, use QueryConditionInterface::isNull() or QueryConditionInterface::isNotNull(). Drupal considers LIKE case insensitive and the following is often us
