      • getParent

        public AbstractContext getParent()
        Returns:
        Returns the parent of this context.
      • isAncestor

        public boolean isAncestor​(AbstractContext context)
        Parameters:
        context -
        Returns:
        true if the context is an ancestor
      • getPropertyNames

        public Iterator<String> getPropertyNames()
        An iterator over a collection of String objects, which are the keys in the properties object.
        Returns:
        Iterator over a collection of keys
      • getProperty

        public Object getProperty​(String key)
        Retrieves an object given a key.
        Parameters:
        key - - if not found, will return null
        Returns:
        Returns the property.
      • getLocalProperty

        public Object getLocalProperty​(String key)
        Retrieves an object given a key. Only searches at this level i.e. getLocalProperty on MessageContext does not look in the OperationContext properties map if a local result is not found.
        Parameters:
        key - - if not found, will return null
        Returns:
        Returns the property.
      • getPropertyNonReplicable

        public Object getPropertyNonReplicable​(String key)
        Retrieves an object given a key. The retrieved property will not be replicated to other nodes in the clustered scenario.
        Parameters:
        key - - if not found, will return null
        Returns:
        Returns the property.
      • setProperty

        public void setProperty​(String key,
                                Object value)
        Store a property in this context
        Parameters:
        key -
        value -
      • setNonReplicableProperty

        public void setNonReplicableProperty​(String key,
                                             Object value)
        Store a property in this context. But these properties should not be replicated when Axis2 is clustered.
        Parameters:
        key -
        value -
      • removeProperty

        public void removeProperty​(String key)
        Remove a property. Only properties at this level will be removed. Properties of the parents cannot be removed using this method.
        Parameters:
        key -
      • removePropertyNonReplicable

        public void removePropertyNonReplicable​(String key)
        Remove a property. Only properties at this level will be removed. Properties of the parents cannot be removed using this method. The removal of the property will not be replicated when Axis2 is clustered.
        Parameters:
        key -
      • getPropertyDifferences

        public Map<String,​Object> getPropertyDifferences()
        Get the property differences since the last transmission by the clustering mechanism
        Returns:
        The property differences
      • clearPropertyDifferences

        public void clearPropertyDifferences()
        Once the clustering mechanism transmits the property differences, it should call this method to avoid retransmitting stuff that has already been sent.
      • setParent

        public void setParent​(AbstractContext context)
        Parameters:
        context -
      • setProperties

        public void setProperties​(Map<String,​Object> properties)
        This will set the properties to the context. But in setting that one may need to "copy" all the properties from the source properties to the target properties. To enable this we introduced a property (COPY_PROPERTIES) so that if set to true, this code will copy the whole thing, without just referencing to the source.
        Parameters:
        properties -
      • mergeProperties

        public void mergeProperties​(Map<String,​Object> props)
        This will do a copy of the given properties to the current properties table.
        Parameters:
        props - The table of properties to copy
      • touch

        protected void touch()
        ServiceContext and ServiceGroupContext are not getting automatically garbage collected. And there is no specific way for some one to go and make it garbage collectible. So the current solution is to make them time out. So the logic is that, there is a timer task in each and every service group which will check for the last touched time. And if it has not been touched for some time, the timer task will remove it from the memory. The touching logic happens like this. Whenever there is a call to addMessageContext in the operationContext it will go and update operationCOntext -> serviceContext -> serviceGroupContext.
