PrintAttributes.Resolution

Kotlin |Java

public static final class PrintAttributes.Resolution
extends Object

java.lang.Object
↳	android.print.PrintAttributes.Resolution

This class specifies a supported resolution in DPI (dots per inch). Resolution defines how many points with different color can be placed on one inch in horizontal or vertical direction of the target media. For example, a printer with 600 DPI can produce higher quality images the one with 300 DPI resolution.

Summary

Public constructors
`Resolution(String id, String label, int horizontalDpi, int verticalDpi)` Creates a new instance.

Public methods
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`int`	`getHorizontalDpi()` Gets the horizontal resolution in DPI (dots per inch).
`String`	`getId()` Gets the unique resolution id.
`String`	`getLabel()` Gets the resolution human readable label.
`int`	`getVerticalDpi()` Gets the vertical resolution in DPI (dots per inch).
`int`	`hashCode()` Returns a hash code value for the object.
`String`	`toString()` Returns a string representation of the object.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Public constructors

Resolution

Added in API level 19

public Resolution (String id, 
                String label, 
                int horizontalDpi, 
                int verticalDpi)

Creates a new instance.

Parameters
`id`	`String`: The unique resolution id. It is unique amongst other resolutions supported by the printer. This value cannot be `null`.
`label`	`String`: The localized human readable label. This value cannot be `null`.
`horizontalDpi`	`int`: The horizontal resolution in DPI (dots per inch). Value is 1 or greater
`verticalDpi`	`int`: The vertical resolution in DPI (dots per inch). Value is 1 or greater

Throws
`IllegalArgumentException`	If the id is empty or the label is empty or the horizontalDpi is less than or equal to zero or the verticalDpi is less than or equal to zero.

Public methods

equals

Added in API level 19

public 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:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values 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.
For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
`obj`	`Object`: This value may be `null`.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getHorizontalDpi

Added in API level 19

public int getHorizontalDpi ()

Gets the horizontal resolution in DPI (dots per inch).

Returns
`int`	The horizontal resolution. Value is 1 or greater

getId

Added in API level 19

public String getId ()

Gets the unique resolution id. It is unique amongst other resolutions supported by the printer.

This id is defined by the client that generated the resolution instance and should not be interpreted by other parties.

Returns
`String`	The unique resolution id. This value cannot be `null`.

getLabel

Added in API level 19

public String getLabel ()

Gets the resolution human readable label.

Returns
`String`	The human readable label. This value cannot be `null`.

getVerticalDpi

Added in API level 19

public int getVerticalDpi ()

Gets the vertical resolution in DPI (dots per inch).

Returns
`int`	The vertical resolution. Value is 1 or greater

hashCode

Added in API level 19

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 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.
If two objects are equal according to the equals method, then calling the hashCode 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 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.

Returns
`int`	a hash code value for this object.

toString

Added in API level 19

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.
