public static final class PrintAttributes.Margins
extends Object
java.lang.Object | |
↳ | android.print.PrintAttributes.Margins |
This class specifies content margins. Margins define the white space around the content where the left margin defines the amount of white space on the left of the content and so on.

boolean equals (Object obj)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation on non-null object references:
x
, x.equals(x)
should return true
. x
and y
, x.equals(y)
should return true
if and only if y.equals(x)
returns true
. x
, y
, and z
, if x.equals(y)
returns true
and y.equals(z)
returns true
, then x.equals(z)
should return true
. x
and y
, multiple invocations of x.equals(y)
consistently return true
or consistently return false
, provided no information used in equals
comparisons on the objects is modified. x
, x.equals(null)
should return false
. The equals
method for class Object
implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x
and y
, this method returns true
if and only if x
and y
refer to the same object (x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the general contract for the hashCode
method, which states that equal objects must have equal hash codes.
Parameters | |
---|---|
obj |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj argument; false otherwise. |
int getBottomMils ()
Gets the bottom margin in mils (thousandths of an inch).
Returns | |
---|---|
int |
The bottom margin. |
int getLeftMils ()
Gets the left margin in mils (thousandths of an inch).
Returns | |
---|---|
int |
The left margin. |
int getRightMils ()
Gets the right margin in mils (thousandths of an inch).
Returns | |
---|---|
int |
The right margin. |
int getTopMils ()
Gets the top margin in mils (thousandths of an inch).
Returns | |
---|---|
int |
The top margin. |
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:
hashCode
method must consistently return the same integer, provided no information used in equals
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. equals(Object)
method, then calling the hashCode
method on each of the two objects must produce the same integer result. equals(java.lang.Object)
method, then calling the hashCode
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. As much as is reasonably practical, the hashCode method defined by class Object
does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
Returns | |
---|---|
int |
a hash code value for this object. |
String toString ()
Returns a string representation of the object. In general, the toString
method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@
', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
