Contains the {@link org.apache.geode.cache.operations.OperationContext} interface that encapsulates an operation and the data associated with it for both the pre-operation and post-operation cases. It also contains implementations of the {@link org.apache.geode.cache.operations.OperationContext} interface for various kinds of cache operations.
These include:{@link org.apache.geode.cache.operations.KeyOperationContext}: Implementation for operations that require a key for the operation. It provides a getKey method to obtain the key. Also provided are setCallbackArg and getCallbackArg methods that can be used to set/get an optional callback argument. The operations returned as KeyOperationContext are {@link org.apache.geode.cache.operations.OperationContext.OperationCode#DESTROY} and {@link org.apache.geode.cache.operations.OperationContext.OperationCode#CONTAINS_KEY}.
{@link org.apache.geode.cache.operations.KeyValueOperationContext}: Implementation for operations that require both key and value for the operation. It extends the {@link org.apache.geode.cache.operations.KeyOperationContext} implementation providing getValue and setValue methods in addition to those provided by the KeyOperationContext class. The operations returned as KeyValueOperationContext are {@link org.apache.geode.cache.operations.OperationContext.OperationCode#GET} and {@link org.apache.geode.cache.operations.OperationContext.OperationCode#PUT}. For the GET operation this is used to both the pre and post operation cases.
{@link org.apache.geode.cache.operations.InterestOperationContext}: Implementation for register and unregister of interest in a region. It defines a sub-class {@link org.apache.geode.cache.operations.InterestType} that encapsulates different kinds of interest viz. KEY, LIST, REGULAR_EXPRESSION, FILTER_CLASS and OQL_QUERY. It provides getInterestType method to get the interest type, getInterestResultPolicy method to get the {@link org.apache.geode.cache.InterestResultPolicy} of the request, isUnregister method that returns true if this is an unregister operation, and getKey/setKey methods to get/set the key being registered. The key may be a single key, a list of keys, a regular expression string or an OQL {@link org.apache.geode.cache.query.Query}.
{@link org.apache.geode.cache.operations.QueryOperationContext}: Implementation for a cache query operation for both the pre and post operation cases. It provides getQuery to get the query string as well as a modifyQuery method to be able to modify it. A utility getRegionNames method is also provided to obtain the list of regions as referenced by the query string. For the results in the post operation phase, getQueryResult allows getting the result and setQueryResult allows modification of the result.
{@link org.apache.geode.cache.operations.RegionOperationContext}: Implementation for the region level operation for the pre operation case. It provides getCallbackArg and setCallbackArg methods to get/set the optionally callback argument. The operations returned as RegionOperationContext are {@link org.apache.geode.cache.operations.OperationContext.OperationCode#REGION_CLEAR} and {@link org.apache.geode.cache.operations.OperationContext.OperationCode#REGION_DESTROY}.
{@link org.apache.geode.cache.operations.DestroyOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#DESTROY} operation having the key object for both the pre-operation and post-operation updates.
{@link org.apache.geode.cache.operations.CloseCQOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#CLOSE_CQ} operation for the pre-operation case.
{@link org.apache.geode.cache.operations.ExecuteCQOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#EXECUTE_CQ} operation for both the pre-operation and post-operation case.
{@link org.apache.geode.cache.operations.ExecuteFunctionOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#EXECUTE_FUNCTION} operation for the pre-operation case.
{@link org.apache.geode.cache.operations.GetOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#GET} operation having the key object for the pre-operation case and both key-value objects for the post-operation case.
{@link org.apache.geode.cache.operations.InvalidateOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#INVALIDATE} region operation having the key object for the pre-operation case and post-operation case.
{@link org.apache.geode.cache.operations.PutOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#PUT} operation having the key and value objects for the pre-operation case and post-operation case.
{@link org.apache.geode.cache.operations.PutAllOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#KEY_SET} operation having the key and value objects for the pre-operation case and post-operation case.
{@link org.apache.geode.cache.operations.RegionCreateOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#REGION_CREATE} operation for the pre-operation case and post-operation case.
{@link org.apache.geode.cache.operations.StopCQOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#STOP_CQ} operation for the pre-operation case.
{@link org.apache.geode.cache.operations.RegisterInterestOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#REGISTER_INTEREST} operation for the pre-operation case, which derives from {@link org.apache.geode.cache.operations.InterestOperationContext}
{@link org.apache.geode.cache.operations.UnregisterInterestOperationContext}: Implementation for {@link org.apache.geode.cache.operations.OperationContext.OperationCode#UNREGISTER_INTEREST} operation for the pre-operation case, which derives from {@link org.apache.geode.cache.operations.InterestOperationContext}
