Condition

org.beangle.data.dao.Condition

See theCondition companion object

class Condition(val content: String, initParams: Any*)

查询条件

使用例子如下

new Condition("std.id=?",new Long(2));
或者 Condition("std.id=:std_id",new Long(2));
?绑定单值.命名参数允许绑定多值.但是只能由字母,数组和下划线组成
一组condition只能采取上面一种形式

Concrete methods

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

It is reflexive: for any instance x of type Any, x.equals(x) should return true.
It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).
