Methods

Append(Int32, E)
Append(Int32, Object)

Puts a key/value pair into the array, optimizing for the case where the key is greater than all existing keys in the array.

(Inherited from SparseArray)
Clear()

Removes all key-value mappings from this SparseArray.

(Inherited from SparseArray)
Clone()

Creates and returns a copy of this Object.

(Inherited from SparseArray)
Contains(Int32)

Returns true if the key exists in the array.

(Inherited from SparseArray)
ContentEquals(SparseArray)

Compares the contents of this SparseArray to the specified SparseArray.

(Inherited from SparseArray)
ContentHashCode()

Returns a hash code value for the contents of this SparseArray, combining the Objects#hashCode(Object) result of all its keys and values.

(Inherited from SparseArray)
Delete(Int32)

Removes the mapping from the specified key, if there was any.

(Inherited from SparseArray)
Dispose() (Inherited from Object)
Dispose(Boolean) (Inherited from Object)
Equals(Object)

Indicates whether some other object is "equal to" this one.

(Inherited from Object)
Get(Int32)

Gets the Object mapped from the specified key, or null if no such mapping has been made.
Get(Int32, E)
Get(Int32, Object)

Gets the Object mapped from the specified key, or the specified Object if no such mapping has been made.

(Inherited from SparseArray)
GetHashCode()

Returns a hash code value for the object.

(Inherited from Object)
IndexOfKey(Int32)

Returns the index for which #keyAt would return the specified key, or a negative number if the specified key is not mapped.

(Inherited from SparseArray)
IndexOfValue(E)
IndexOfValue(Object)

Returns an index for which #valueAt would return the specified value, or a negative number if no keys map to the specified value.

(Inherited from SparseArray)
JavaFinalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

(Inherited from Object)
KeyAt(Int32)

Given an index in the range <code>0.

(Inherited from SparseArray)
Notify()

Wakes up a single thread that is waiting on this object's monitor.

(Inherited from Object)
NotifyAll()

Wakes up all threads that are waiting on this object's monitor.

(Inherited from Object)
Put(Int32, E)
Put(Int32, Object)

Adds a mapping from the specified key to the specified value, replacing the previous mapping from the specified key if there was one.

(Inherited from SparseArray)
Remove(Int32)

Alias for #delete(int).

(Inherited from SparseArray)
RemoveAt(Int32)

Removes the mapping at the specified index.

(Inherited from SparseArray)
RemoveAtRange(Int32, Int32)

Remove a range of mappings as a batch.

(Inherited from SparseArray)
Set(Int32, Object)

Alias for #put(int, Object) to support Kotlin [index]= operator.

(Inherited from SparseArray)
SetHandle(IntPtr, JniHandleOwnership)

Sets the Handle property.

(Inherited from Object)
SetValueAt(Int32, E)
SetValueAt(Int32, Object)

Given an index in the range <code>0.

(Inherited from SparseArray)
Size()

Returns the number of key-value mappings that this SparseArray currently stores.

(Inherited from SparseArray)
ToArray<T>() (Inherited from Object)
ToString()

Returns a string representation of the object.

(Inherited from Object)
UnregisterFromRuntime() (Inherited from Object)
ValueAt(Int32)

Given an index in the range 0...size()-1, returns the value from the indexth key-value mapping that this SparseArray stores.
Wait()

Causes the current thread to wait until another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object.

(Inherited from Object)
Wait(Int64)

Causes the current thread to wait until either another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object, or a specified amount of time has elapsed.

(Inherited from Object)
Wait(Int64, Int32)

Causes the current thread to wait until another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.

(Inherited from Object)
