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()Returns a hash code value for the object. |
| Properties | |
|---|---|
| Int |
The pointer id. |
| Int |

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
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons 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. |
hashCode
fun hashCode(): Int
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by 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
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons 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
equalsmethod, then calling thehashCodemethod 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
equalsmethod, then calling thehashCodemethod 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.
| Return | |
|---|---|
Int |
a hash code value for this object. |
