Remarks
Dispose the object to avoid a resource leak, the object contains a reference to the corresponding JVM object
Constructors
Deserializer(IJVMBridgeBaseInitializer)
Initializer used internally by JCOBridge. Do not use directly.
[Obsolete("This public initializer is needed for JCOBridge internal use, other uses can produce unidentifiable behaviors.")]
public Deserializer(IJVMBridgeBaseInitializer initializer)Parameters
initializerIJVMBridgeBaseInitializer
Deserializer(params object[])
Generic constructor used by JCOBridge when a derived class needs to forward arguments to the base JVMBridgeBase class.
public Deserializer(params object[] args)Parameters
argsobject[]
Properties
BridgeClassName
Java class name to be instantiated
public override string BridgeClassName { get; }Property Value
OnClose
public Action OnClose { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnConfigure
public Action<Map<String, object>, bool> OnConfigure { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDeserialize
public Func<String, byte[], T> OnDeserialize { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDeserialize3
public Func<String, Headers, byte[], T> OnDeserialize3 { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDeserialize3Dispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<T> OnDeserialize3Dispose { get; set; }Property Value
- Action<T>
Remarks
Set OnDeserialize3Dispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnDeserialize3_2
public Func<String, Headers, ByteBuffer, T> OnDeserialize3_2 { get; set; }Property Value
- Func<String, Headers, ByteBuffer, T>
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDeserialize3_2Dispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<T> OnDeserialize3_2Dispose { get; set; }Property Value
- Action<T>
Remarks
Set OnDeserialize3_2Dispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnDeserializeDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<T> OnDeserializeDispose { get; set; }Property Value

Remarks
Set OnDeserializeDispose when the event handler returns a JVM-backed object that is no longer needed after the call.

InitializeHandlers(Type)
Handlers initializer for Deserializer
protected virtual void InitializeHandlers(Type listenerRuntimeType)Parameters
listenerRuntimeTypeType
ListenerShallManageEvent(int)
Invoked from the JVMBridgeListener on each received event to notify the user which can decide to abort the execution for the specific event returning false
protected override bool ListenerShallManageEvent(int eventIndex)Parameters
eventIndexintThe index of the event triggered as returned from AddEventHandler(string, EventHandler) or AddEventHandler<TDataClass>(string, EventHandler<CLRListenerEventArgs<TDataClass>>)
Returns
Remarks
By default every event continues the execution and reads the data from JVM; this implies an extra cost which can be limited using ListenerShallManageEvent(int) or the ListenerShallManageEventIndex/ListenerShallManageEventName handlers. Returning false the control is immediately returned to the JVM, anyway the user has received the notification. It can be useful in scenarios where the user is interested in few events and the other are simply discarded to optimize the execution speed. By default, this function invokes ListenerShallManageEventIndex, then try ListenerShallManageEventName if they are set or return true
