Method Detail

compare

public int compare(Property o1,
                   Property o2)

compare method. Assumes both parameters are non-null instances of Property. One property is less than another if its name is shorter than the other property's name. If the names are the same length, the property whose name comes before the other property's name, alphabetically, is less than the other property. (比较方法。假设这两个参数都是 Property 的非空实例。如果一个属性的名称短于另一个属性的名称，则该属性小于另一个属性。如果名称长度相同，则名称在其他属性名称之前的属性（按字母顺序）小于其他属性。)

Specified by:

compare in interface java.util.Comparator<Property> (在接口 java.util.Comparator 中比较 )

Parameters:

o1 - first object to compare, better be a Property (o1 - 第一个要比较的对象，最好是一个属性)

o2 - second object to compare, better be a Property (o2 - 要比较的第二个对象，最好是一个属性)

Returns:

negative value if o1 < o2, zero if o1 == o2, positive value if o1 > o2. (如果 o1 < o2 则为负值，如果 o1 == o2 则为零，如果 o1 > o2 则为正值。)
