Builder manipulates a tree structure consisting of net.esper.filter.FilterCallbackSetNode and net.esper.filter.FilterParamIndex instances. Filters can be added to a top node (an instance of FilterCallbackSetNode) via the add method. This method returns an instance of net.esper.filter.IndexTreePath which represents the tree path (list of indizes) that the filter callback was added to. To remove filters the same IndexTreePath instance must be passed in.

The implementation is designed to be multithread-safe in conjunction with the node classes manipulated by this class.

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

Public Methods

  NameDescription
Add
Add a filter callback according to the filter specification to the top node returninginformation to be used to remove the filter callback.

static memberCopySortParameters
Copy the parameter list - this also sorts the parameter list.

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.)
Remove
Remove an filterCallback from the given top node. The IndexTreePath instance passed in must be thesame as obtained when the same filterCallback was added.

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.)
