Constructors

SparseIntArray() SparseIntArray()

Creates a new SparseIntArray containing no mappings.

SparseIntArray(Int32) SparseIntArray(Int32)

Creates a new SparseIntArray containing no mappings that will not require any additional memory allocation to store the specified number of mappings.

SparseIntArray(IntPtr, JniHandleOwnership) SparseIntArray(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Methods

Append(Int32, Int32) Append(Int32, Int32)

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

Clear() Clear()

Removes all key-value mappings from this SparseIntArray.

Clone() Clone()

Creates and returns a copy of this Object.

Delete(Int32) Delete(Int32)

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

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

Compares this instance with the specified object and indicates if they are equal.

(Inherited from Object)
Get(Int32) Get(Int32)

Gets the int mapped from the specified key, or 0 if no such mapping has been made.

Get(Int32, Int32) Get(Int32, Int32)

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

GetHashCode() GetHashCode()

Returns an integer hash code for this object.

(Inherited from Object)
IndexOfKey(Int32) IndexOfKey(Int32)

Returns the index for which KeyAt(Int32) would return the specified key, or a negative number if the specified key is not mapped.

IndexOfValue(Int32) IndexOfValue(Int32)

Returns an index for which ValueAt(Int32) would return the specified key, or a negative number if no keys map to the specified value.

JavaFinalize() JavaFinalize()

Invoked when the garbage collector has detected that this instance is no longer reachable.

(Inherited from Object)
KeyAt(Int32) KeyAt(Int32)

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

Notify() Notify()

Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
NotifyAll() NotifyAll()

Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

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

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

RemoveAt(Int32) RemoveAt(Int32)

Removes the mapping at the given index.

SetHandle(IntPtr, JniHandleOwnership) SetHandle(IntPtr, JniHandleOwnership)

Sets the Handle property.

(Inherited from Object)
Size() Size()

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

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

Returns a string containing a concise, human-readable description of this object.

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

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

Wait() Wait()

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

(Inherited from Object)
Wait(Int64) Wait(Int64)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

(Inherited from Object)
Wait(Int64, Int32) Wait(Int64, Int32)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
