Represents an stream property identifier in a filter expressiun tree.

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

Public Methods

  NameDescription
Accept
Accept the visitor. The visitor will first visit the parent then visit all child nodes, then their child nodes. The visitor can decide to skip child nodes by returning false in isVisit.
(Inherited from ExprNode.)
AddChildNode
Adds a child node.
(Inherited from ExprNode.)
DumpDebug
Recursively print out all nodes.
(Inherited from ExprNode.)
Equals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
EqualsNode
Return true if a expression node semantically equals the current node, or false if not. Concrete implementations should compare the type and any additional information that impact the evaluation of a node.
(Overrides .EqualsNode(ExprNode).)
Evaluate
Evaluate event tuple and return result.
(Overrides .Evaluate(EventBean[]()).)
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.)
GetValidatedSubtree
Validates the expression node subtree that has this node as root. Some of the nodes of the tree, including the root, might be replaced in the process.
(Inherited from ExprNode.)
ToString
Returns a String that represents the current Object.
(Overrides .ToString().)
Validate
Validate node.
(Overrides .Validate(StreamTypeService, AutoImportService).)

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.)
static memberGetTypeFromStream
Determine stream id and property type given an unresolved property name anda stream name that may also be part of the property name.<p>For example: select s0.p1 from... p1 is the property name, s0 the stream name, however this could also be a nested property

MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)

Public Constructors

Public Properties

  NameDescription
ChildNodes
Returns list of child nodes.
(Inherited from ExprNode.)
ExpressionString
Returns the expression node rendered as a string.
(Overrides .ExpressionString.)
ResolvedPropertyName
Return property name as resolved by lookup in streams.

ResolvedStreamName
Returns stream name as resolved by lookup of property in streams.

ReturnType
Returns the type that the node's evaluate method returns an instance of.
(Overrides .ReturnType.)
StreamId
Gets the stream id supplying the property value

StreamOrPropertyName
For unit testing, returns stream or property name candidate.

UnresolvedPropertyName
For unit testing, returns unresolved property name.
