Remarks

An object that registers to be notified of events that occur on PreparedStatements that are in the Statement pool.

The JDBC 3.0 specification added the maxStatements ConnectionPooledDataSource property to provide a standard mechanism for enabling the pooling of PreparedStatements and to specify the size of the statement pool. However, there was no way for a driver to notify an external statement pool when a PreparedStatement becomes invalid. For some databases, a statement becomes invalid if a DDL operation is performed that affects the table. For example an application may create a temporary table to do some work on the table and then destroy it. It may later recreate the same table when it is needed again. Some databases will invalidate any prepared statements that reference the temporary table when the table is dropped.

Similar to the methods defined in the ConnectionEventListener interface, the driver will call the StatementEventListener.statementErrorOccurred method prior to throwing any exceptions when it detects a statement is invalid. The driver will also call the StatementEventListener.statementClosed method when a PreparedStatement is closed.

Methods which allow a component to register a StatementEventListener with a PooledConnection have been added to the PooledConnection interface.

Added in 1.6.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
StatementClosed(StatementEvent)	The driver calls this method on all `StatementEventListener`s registered on the connection when it detects that a `PreparedStatement` is closed.
StatementErrorOccurred(StatementEvent)	The driver calls this method on all `StatementEventListener`s registered on the connection when it detects that a `PreparedStatement` is invalid.
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
