public static DispatchStatus ___ice_isA(Object __obj,
                                        Incoming __inS,
                                        Current __current)

ice_ping

public void ice_ping()

Tests whether this object can be reached.

Specified by:

ice_ping in interface Object

ice_ping

public void ice_ping(Current current)

Tests whether this object can be reached.

Specified by:

ice_ping in interface Object

Parameters:

current - The current object for the invocation.

___ice_ping

public static DispatchStatus ___ice_ping(Object __obj,
                                         Incoming __inS,
                                         Current __current)

ice_ids

public java.lang.String[] ice_ids()

Returns the Slice type IDs of the interfaces supported by this object.

Specified by:

ice_ids in interface Object

Returns:

An array whose only element is ::Ice::Object.

ice_ids

public java.lang.String[] ice_ids(Current current)

Returns the Slice type IDs of the interfaces supported by this object.

Specified by:

ice_ids in interface Object

Parameters:

current - The current object for the invocation.

Returns:

An array whose only element is ::Ice::Object.

___ice_ids

public static DispatchStatus ___ice_ids(Object __obj,
                                        Incoming __inS,
                                        Current __current)

ice_id

public java.lang.String ice_id()

Returns the Slice type ID of the most-derived interface supported by this object.

Specified by:

ice_id in interface Object

Returns:

The return value is always ::Ice::Object.

ice_id

public java.lang.String ice_id(Current current)

Returns the Slice type ID of the most-derived interface supported by this object.

Specified by:

ice_id in interface Object

Parameters:

current - The current object for the invocation.

Returns:

A Slice type ID.

___ice_id

public static DispatchStatus ___ice_id(Object __obj,
                                       Incoming __inS,
                                       Current __current)

ice_staticId

public static java.lang.String ice_staticId()

Returns the Slice type ID of the interface supported by this object.

Returns:

The return value is always ::Ice::Object.

ice_operationAttributes

public int ice_operationAttributes(java.lang.String operation)

Returns the Freeze metadata attributes for an operation.

Specified by:

ice_operationAttributes in interface Object

Parameters:

operation - The name of the operation.

Returns:

The least significant bit indicates whether the operation is a read or write operation. If the bit is set, the operation is a write operation. The expression ice_operationAttributes("op") & 0x1 is true if the operation has a ["freeze:write"] metadata directive.

The second and third least significant bit indicate the transactional mode of the operation. The expression ice_operationAttributes("op") & 0x6 >> 1 indicates the transactional mode as follows:

0

["freeze:read:supports"]

1

["freeze:read:mandatory"] or ["freeze:write:mandatory"]

2

["freeze:read:required"] or ["freeze:write:required"]

3

["freeze:read:never"]

ice_preMarshal

public void ice_preMarshal()

The Ice run time invokes this method prior to marshaling an object's data members. This allows a subclass to override this method in order to validate its data members. This default implementation does nothing.

Specified by:

ice_preMarshal in interface Object

ice_postUnmarshal

public void ice_postUnmarshal()

This Ice run time invokes this method vafter unmarshaling an object's data members. This allows a subclass to override this method in order to perform additional initialization. This default implementation does nothing.

Specified by:

ice_postUnmarshal in interface Object

ice_dispatch

public DispatchStatus ice_dispatch(Request request,
                                   DispatchInterceptorAsyncCallback cb)

Dispatches an invocation to a servant. This method is used by dispatch interceptors to forward an invocation to a servant (or to another interceptor).

Specified by:

ice_dispatch in interface Object

Parameters:

request - The details of the invocation.

cb - The callback object for asynchchronous dispatch. For synchronous dispatch, the callback object must be null.

Returns:

The dispatch status for the operation.
