PointerProperties
class PointerProperties
kotlin.Any | |
↳ | android.view.MotionEvent.PointerProperties |
Transfer object for pointer properties. Objects of this type can be used to specify the pointer id and tool type when creating new MotionEvent
objects and to query pointer properties in bulk.
Summary
Public constructors | |
---|---|
Creates a pointer properties object with an invalid pointer id. |
|
Creates a pointer properties object as a copy of the contents of another pointer properties object. |
Public methods | |
---|---|
Unit |
clear() Resets the pointer properties to their initial values. |
Unit |
copyFrom(other: MotionEvent.PointerProperties!) Copies the contents of another pointer properties object. |
Boolean |
Indicates whether some other object is "equal to" this one. |
Int |
hashCode() |
Properties | |
---|---|
Int |
The pointer id. |
Int |
The pointer tool type. |
Public constructors
PointerProperties
PointerProperties()
Creates a pointer properties object with an invalid pointer id.
PointerProperties
PointerProperties(other: MotionEvent.PointerProperties!)
Creates a pointer properties object as a copy of the contents of another pointer properties object.
Parameters | |
---|---|
other |
MotionEvent.PointerProperties!: |
Public methods
clear
fun clear(): Unit
Resets the pointer properties to their initial values.
copyFrom
fun copyFrom(other: MotionEvent.PointerProperties!): Unit
Copies the contents of another pointer properties object.
Parameters | |
---|---|
other |
MotionEvent.PointerProperties!: The pointer properties object to copy. |
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. |
