Insets
extends Object

Parcelable
java.lang.Object | |
↳ | android.graphics.Insets |
An Insets instance holds four integer offsets which describe changes to the four edges of a Rectangle. By convention, positive values move edges towards the centre of the rectangle.
Insets are immutable so may be treated as values.

Fields
Public methods
add
public static Insets add (Insets a, Insets b)
Add two Insets.
Parameters | |
---|---|
a |
Insets : The first Insets to add.
This value cannot be null . |
b |
Insets : The second Insets to add.
This value cannot be null . |
Returns | |
---|---|
Insets |
a + b, i. e. all insets on every side are added together.
This value cannot be null . |
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
equals
public boolean equals (Object o)
Two Insets instances are equal iff they belong to the same class and their fields are pairwise equal.
Parameters | |
---|---|
o |
Object : the object to compare this instance with. |
Returns | |
---|---|
boolean |
true iff this object is equal o |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
max
public static Insets max (Insets a, Insets b)
Retrieves the maximum of two Insets.
Parameters | |
---|---|
a |
Insets : The first Insets.
This value cannot be null . |
b |
Insets : The second Insets.
This value cannot be null . |
Returns | |
---|---|
Insets |
max(a, b), i. e. the larger of every inset on every side is taken for the result.
This value cannot be null . |
min
public static Insets min (Insets a, Insets b)
Retrieves the minimum of two Insets.
Parameters | |
---|---|
a |
Insets : The first Insets.
This value cannot be null . |
b |
Insets : The second Insets.
This value cannot be null . |
Returns | |
---|---|
Insets |
min(a, b), i. e. the smaller of every inset on every side is taken for the result.
This value cannot be null . |
of
public static Insets of (int left, int top, int right, int bottom)
Return an Insets instance with the appropriate values.
Parameters | |
---|---|
left |
int : the left inset |
top |
int : the top inset |
right |
int : the right inset |
bottom |
int : the bottom inset |
Returns | |
---|---|
Insets |
Insets instance with the appropriate values

of
public static Insets of (Rect r)
Return an Insets instance with the appropriate values.
Parameters | |
---|---|
r |
Rect : the rectangle from which to take the values
This value may be null . |
Returns | |
---|---|
Insets |
an Insets instance with the appropriate values
This value cannot be null . |
subtract
public static Insets subtract (Insets a, Insets b)
Subtract two Insets.
Parameters | |
---|---|

This value cannot be null . |
Returns | |
---|---|
Insets |
a - b, i. e. all insets on every side are subtracted from each other.
This value cannot be null . |
toString
