Public methods

clear

fun clear(): Unit

Removes all values.

containsKey

Added in API level 1
fun containsKey(key: String!): Boolean

Returns true if this object has the named value.

Parameters
key String!: the value to check for
Return
Boolean true if the value is present, false otherwise

describeContents

Added in API level 1
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

Added in API level 1
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 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 the reference object with which to compare.
object This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.
