pack-priv Class Level.RectXComparator

All Implemented Interfaces
java.util.Comparator

Constructor Summary

AccessConstructor and Description
pack-priv
RectXComparator()

Method Summary

Modifier and TypeMethod and Description
public int
compare(final Rect
the first object to be compared.
r1, final Rect
the second object to be compared.
r2)

Implements java.util.Comparator.compare.

Compares its two arguments for order.
public boolean
equals(final Object
the reference object with which to compare.
obj)

Overrides java.lang.Object.equals.

Implements java.util.Comparator.equals.

Indicates whether some other object is "equal to" this comparator.

Method Detail

compareback to summary
public int compare(final Rect r1, final Rect r2)

Implements java.util.Comparator.compare.

Doc from java.util.Comparator.compare.

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The implementor must ensure that signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)

The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.

Parameters
r1:Rect

the first object to be compared.

r2:Rect

the second object to be compared.

Returns:int

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

equalsback to summary
public boolean equals(final Object obj)

Overrides java.lang.Object.equals.

Implements java.util.Comparator.equals.

Doc from java.util.Comparator.equals.

Indicates whether some other object is "equal to" this comparator. This method must obey the general contract of Object#equals(Object). Additionally, this method can return true only if the specified object is also a comparator and it imposes the same ordering as this comparator. Thus, comp1.equals(comp2) implies that signum(comp1.compare(o1, o2))==signum(comp2.compare(o1, o2)) for every object reference o1 and o2.

Note that it is always safe not to override Object.equals(Object). However, overriding this method may, in some cases, improve performance by allowing programs to determine that two distinct comparators impose the same order.

Parameters
obj:Object

the reference object with which to compare.

Returns:boolean

true only if the specified object is also a comparator and it imposes the same ordering as this comparator.
