public abstract class OperationContext
extends Object

Encapsulates a cache operation and the data associated with it for both the pre-operation and post-operation cases. Implementations for specific operations will extend this with the specifics as required e.g. a getKey() method for a GET operation. Implementations for all the cache operations that require authorization are provided. Implementations of this interface are not expected to be thread-safe.

Method Detail

getOperationCode

public abstract OperationContext.OperationCode getOperationCode()

Return the operation code associated with the OperationContext object.

isPostOperation

public abstract boolean isPostOperation()

True if the context is for post-operation. The OperationContext interface encapsulates the data both before the operation is performed and after the operation is complete. For example, for a query operation the Query object as well as the list of region names referenced by the query would be part of the context object in the pre-processing stage. In the post-processing stage the context object shall contain results of the query.

isClientUpdate

public boolean isClientUpdate(OperationContext context)

True if the context is created before sending the updates to a client.
