This class holds a list of indizes storing filter constants in net.esper.filter.FilterParamIndex nodes and a set of net.esper.filter.FilterCallback. An instance of this class represents a leaf-node (no indizes stored, just filter callbacks) but can also be non-leaf (some indizes exist) in a filter evaluation tree. Events are evaluated by asking each of the indizes to evaluate the event and by adding any filter callbacks in this node to the "matches" list of callbacks.

The following tables list the members exposed by the FilterCallbackSetNode type.

Public Methods

  NameDescription
AddOverloaded.
Contains
Returns an indication whether the filter callback exists in this node.

NOTE: the client to this method must use the read-write lock of this object to lock, if required by the clientcode.


Equals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
GetHashCode
Serves as a hash function for a particular type. GetHashCode() is suitable for use in hashing algorithms and data structures like a hash table.
(Inherited from Object.)
GetType
Gets the Type of the current instance.
(Inherited from Object.)
MatchEvent
Evaluate an event by asking each index to match the event. Any filter callbacks at this node automaticallymatch the event and do not need to be further evaluated, and are thus added to the "matches" list of callbacks.

NOTE: This client should not use the lock before calling this method.


RemoveOverloaded.
ToString
Returns a String that represents the current Object.
(Inherited from Object.)

Protected Methods

  NameDescription
Finalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)

Public Constructors

  NameDescription
FilterCallbackSetNodeNew
Initializes a new instance of the FilterCallbackSetNode class.

Public Properties

  NameDescription
FilterCallbackCount
Returns the number of filter callbacks stored.

NOTE: the client to this method must use the read-write lock of this object to lock, if required by the clientcode.


Indizes
Returns list of indexes - not returning an iterator. Client classes should not change this collection.

IsEmpty
Returns an indication of whether there are any callbacks or index nodes at all in this set.

NOTE: the client to this method must use the read-write lock of this object to lock, if required by the clientcode.


NodeRWLock
Returns to lock to use for making changes to the filter callback or inzides collections stored by this node.
