    • Constructor Detail

      • DefaultEnvironment

        public DefaultEnvironment​(Map<String,​?> seed)

    • Method Detail

      • getSecurityManager

        public SecurityManager getSecurityManager()
                                           throws IllegalStateException
        Returns the application's SecurityManager instance accessible in the backing map using the securityManagerName property as the lookup key.

        This implementation guarantees that a non-null instance is always returned, as this is expected for Environment API end-users. If subclasses have the need to perform the map lookup without this guarantee (for example, during initialization when the instance may not have been added to the map yet), the lookupSecurityManager() method is provided as an alternative.

        Specified by:
        getSecurityManager in interface Environment
        Returns:
        the application's SecurityManager instance accessible in the backing map using the securityManagerName property as the lookup key.
        Throws:
        IllegalStateException
      • lookupSecurityManager

        protected SecurityManager lookupSecurityManager()
        Looks up the SecurityManager instance in the backing map without performing any non-null guarantees.
        Returns:
        the SecurityManager in the backing map, or null if it has not yet been populated.
      • getSecurityManagerName

        public String getSecurityManagerName()
        Returns the name of the SecurityManager instance in the backing map. Used as a key to lookup the instance. Unless set otherwise, the default is securityManager.
        Returns:
        the name of the SecurityManager instance in the backing map. Used as a key to lookup the instance.
      • setSecurityManagerName

        public void setSecurityManagerName​(String securityManagerName)
        Sets the name of the SecurityManager instance in the backing map. Used as a key to lookup the instance. Unless set otherwise, the default is securityManager.
        Parameters:
        securityManagerName - the name of the SecurityManager instance in the backing map. Used as a key to lookup the instance. 
      • getObjects

        public Map<String,​ObjectgetObjects()
        Returns the live (modifiable) internal objects collection.
        Returns:
        the live (modifiable) internal objects collection.

        public <T> T getObject​(String name,
                               Class<T> requiredType)
                        throws RequiredTypeException
        Description copied from interface: NamedObjectEnvironment
        Returns the object in Shiro's environment with the specified name and type or null if no object with that name was found.

        Throws:
        RequiredTypeException - if the discovered object does not equal, extend, or implement the specified class.
      • destroy

        public void destroy()
                     throws Exception
