Remarks
Utility methods useful for working with android.net.Uri objects that use the "content" (content://) scheme.
Content URIs have the syntax
content://<em>authority</em>/<em>path</em>/<em>id</em>
<dl> <dt> content:</dt> <dd> The scheme portion of the URI. This is always set to android.content.ContentResolver#SCHEME_CONTENT ContentResolver.SCHEME_CONTENT (value content://). </dd> <dt> <em>authority</em> </dt> <dd> A string that identifies the entire content provider. All the content URIs for the provider start with this string. To guarantee a unique authority, providers should consider using an authority that is the same as the provider class' package identifier. </dd> <dt> <em>path</em> </dt> <dd> Zero or more segments, separated by a forward slash (/), that identify some subset of the provider's data. Most providers use the path part to identify individual tables. Individual segments in the path are often called "directories" although they do not refer to file directories. The right-most segment in a path is often called a "twig" </dd> <dt> <em>id</em> </dt> <dd> A unique numeric identifier for a single row in the subset of data identified by the preceding path part. Most providers recognize content URIs that contain an id part and give them special handling. A table that contains a column named _ID often expects the id part to be a particular value for that column. </dd> </dl>

Methods
| Name | Description |
|---|---|
| AppendId(Uri+Builder, Int64) |
Appends the given ID to the end of the path. |
| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Construct(JniObjectReference, JniObjectReferenceOptions) |
Delegates construction of this peer to the runtime's value manager. (Inherited from JavaObject) |
| Dispose() |
Releases the resources held by this Java peer. (Inherited from Object) |
| Dispose(Boolean) |
Releases the resources held by this Java peer. (Inherited from Object) |
| DisposeUnlessReferenced() |

| Equals(Object) |
Tests whether another managed peer refers to the same Java object. (Inherited from JavaObject) |
| Equals(Object) |
Indicates whether some other object is "equal to" this one. (Inherited from Object) |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| JavaFinalize() |
Obsolete.
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| 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) |
| ParseId(Uri) |
Converts the last path segment to a long. |
| RemoveId(Uri) |
Removes any ID from the end of the path. |
| SetHandle(IntPtr, JniHandleOwnership) |
Sets the Handle property. (Inherited from Object) |
| SetPeerReference(JniObjectReference, JniObjectReferenceOptions) |
Stores a reference value in the control block without creating a JNI reference copy. (Inherited from JavaObject) |
| ToArray<T>() |
Creates a managed array from this Java array wrapper. (Inherited from Object) |
| ToString() |
Returns a string representation of the object. (Inherited from Object) |
| UnregisterFromRuntime() |
Unregisters this Java peer from the interop runtime. (Inherited from Object) |
| Wait() |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object) |
| Wait(Int64, Int32) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
| Wait(Int64) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
| WithAppendedId(Uri, Int64) |
Appends the given ID to the end of the path. |
