PrintAttributes.Resolution

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

Class Overview

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.

Public Constructors

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

Creates a new instance.

Parameters
id The unique resolution id. It is unique amongst other resolutions supported by the printer.
label The localized human readable label.
horizontalDpi The horizontal resolution in DPI (dots per inch).
verticalDpi The vertical resolution in DPI (dots per inch).
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

public boolean equals ( Object obj)

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o . See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
obj the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object ; false otherwise.

public int getHorizontalDpi ()

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

Returns
  • The horizontal resolution.

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
  • The unique resolution id.

public String getLabel ()

Gets the resolution human readable label.

Returns
  • The human readable label.

public int getVerticalDpi ()

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

Returns
  • The vertical resolution.

public int hashCode ()

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.

public String toString ()

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 

          getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns
  • a printable representation of this object.
