Constants
Public constructors
ContentValues
ContentValues()
Creates an empty set of values using the default initial size
ContentValues
ContentValues(size: Int)
Creates an empty set of values using the given initial size
| Parameters | |
|---|---|
size |
Int: the initial size of the set of values |

Public methods
containsKey
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
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
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 | |

the reference object with which to compare. |

Boolean |
true if this object is the same as the obj argument; false otherwise. |
