public String toString()
The string representation is: ORDER BY

toString

Object.toString()
public int hashCode()
The hash code of a sequence of orders is defined to be the sum of the hash codes of its elements. This ensures that o1.equals(o2)
implies that o1.hashCode() == o2.hashCode()
for any two sequence of orders o1
and o2
, as required by the general contract of Object.hashCode()
.
hashCode
in class Object
Object.hashCode()
public boolean equals(Object obj)
Returns true
if the given object is also a sequence of orders and the two orders represent the same sequence of orders. Two sequences of orders o1
and o2
represent the same sequence of orders if they have the same sizes and, if for each corresponding element o1 and o2, o1.equals(o2)
returns true
.
This implementation first checks if the specified object is this sequence of orders; if so it returns true
. Then, it checks if the specified sequence of orders have the same size as this, and their corresponding elements are equal as described above.
