Interface WriteCommand

    • Method Detail

      • isSuccessful

        boolean isSuccessful()
        Some commands may want to provide information on whether the command was successful or not. This is different from a failure, which usually would result in an exception being thrown. An example is a putIfAbsent() not doing anything because the key in question was present. This would result in a isSuccessful() call returning false.
        Specified by:
        isSuccessful in interface ReplicableCommand
        Returns:
        true if the command completed successfully, false otherwise.
      • isConditional

        boolean isConditional()
        Certain commands only work based on a certain condition or state of the cache. For example, ConcurrentMap.putIfAbsent(Object, Object) only does anything if a condition is met, i.e., the entry in question is not already present. This method tests whether the command in question is conditional or not.
        Returns:
        true if the command is conditional, false otherwise
      • getValueMatcher

        ValueMatcher getValueMatcher()
        Returns:
        The current value matching policy.
      • setValueMatcher

        void setValueMatcher​(ValueMatcher valueMatcher)
        Parameters:
        valueMatcher - The new value matching policy.
      • getAffectedKeys

        Collection<?> getAffectedKeys()
        Returns:
        a collection of keys affected by this write command. Some commands - such as ClearCommand - may return an empty collection for this method.
      • updateStatusFromRemoteResponse

        @Deprecated
        default void updateStatusFromRemoteResponse​(Object remoteResponse)
        Deprecated.
        since 9.1
        Used for conditional commands, to update the status of the command on the originator based on the result of its execution on the primary owner.
      • fail

        void fail()
        Make subsequent invocations of isSuccessful() return false.
      • isWriteOnly

        default boolean isWriteOnly()
        Indicates whether the command is write-only, meaning that it makes no attempt to read the previously associated value with key for which the command is directed.
        Returns:
        true is the command is write only, false otherwise.
