*** ** * ** *** 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 ||

19](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/reference/java/lang/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](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/reference/java/lang/String) | The unique resolution id. This value cannot be`null`.
| ### getLabel Added in[API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getLabel () ``` Gets the resolution human readable label.
| Returns || |--------------------------------------------------------------------|--------------------------------------------------------------| | [String](https://developer.android.com/reference/java/lang/String) | The human readable label. This value cannot be`null`.
| ### getVerticalDpi Added in[API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/reference/java/util/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](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object))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](https://developer.android.com/reference/java/lang/Object#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.

| Returns || |-------|-------------------------------------------| | `int` | a hash code value for this object.
| ### toString Added in[API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String toString () ``` Returns a string representation of the object.
| Returns || |--------------------------------------------------------------------|-----------------------------------------------| | [String](https://developer.android.com/reference/java/lang/String) | a string representation of the object.
