Public methods
describeContents
fun describeContents(): Int
Return | |
---|---|
Int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR |
equals
fun equals(other: Any?): Boolean
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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 |
the reference object with which to compare. |
other |
Any?: This value may be null . |
Return | |
---|---|
Boolean |
true if this object is the same as the obj argument; false otherwise. |
getAlternativeRefreshRates
fun getAlternativeRefreshRates(): FloatArray
Returns an array of refresh rates which can be switched to seamlessly.
A seamless switch is one without visual interruptions, such as a black screen for a second or two.
Presence in this list does not guarantee a switch will occur to the desired refresh rate, but rather, if a switch does occur to a refresh rate in this list, it is guaranteed to be seamless.
The binary relation "refresh rate X is alternative to Y" is non-reflexive, symmetric and transitive. For example the mode 1920x1080 60Hz, will never have an alternative refresh rate of 60Hz. If 1920x1080 60Hz has an alternative of 50Hz then 1920x1080 50Hz will have alternative refresh rate of 60Hz. If 1920x1080 60Hz has an alternative of 50Hz and 1920x1080 50Hz has an alternative of 24Hz, then 1920x1080 60Hz will also have an alternative of 24Hz.

getPhysicalHeight
fun getPhysicalHeight(): Int
Returns the physical height of the display in pixels when configured in this mode's resolution.
Note that due to application UI scaling, the number of pixels made available to applications when the mode is active (as reported by Display.getHeight()
may differ from the mode's actual resolution (as reported by this function).
For example, applications running on a 4K display may have their UI laid out and rendered in 1080p and then scaled up. Applications can take advantage of the extra resolution by rendering content through a android.view.SurfaceView
using full size buffers.
getPhysicalWidth
fun getPhysicalWidth(): Int
Returns the physical width of the display in pixels when configured in this mode's resolution.
Note that due to application UI scaling, the number of pixels made available to applications when the mode is active (as reported by Display.getWidth()
may differ from the mode's actual resolution (as reported by this function).
For example, applications running on a 4K display may have their UI laid out and rendered in 1080p and then scaled up. Applications can take advantage of the extra resolution by rendering content through a android.view.SurfaceView
using full size buffers.
getRefreshRate
fun getRefreshRate(): Float
Returns the refresh rate in frames per second.
getSupportedHdrTypes
fun getSupportedHdrTypes(): IntArray
Returns the supported HdrCapabilities
HDR_TYPE_* for this specific mode
toString
fun toString(): String
Return | |
---|---|
String |
a string representation of the object. |
writeToParcel
fun writeToParcel(
out: Parcel,
parcelableFlags: Int
): Unit
Parameters | |
---|---|
dest |
The Parcel in which the object should be written. This value cannot be null . |
flags |
Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
