Remarks

A CorrelationRuleFilter holds a set of conditions that are matched against one of more of an arriving message's user and system properties. A common use is a match against the CorrelationId property, but the application can also choose to match against ContentType, Subject, MessageId, ReplyTo, ReplyToSessionId, SessionId, To, and any user-defined properties. A match exists when an arriving message's value for a property is equal to the value specified in the correlation filter. For string expressions, the comparison is case-sensitive. When specifying multiple match properties, the filter combines them as a logical AND condition, meaning all conditions must match for the filter to match.

The CorrelationRuleFilter provides an efficient shortcut for declarations of filters that deal only with correlation equality. In this case the cost of the lexicographical analysis of the expression can be avoided. Not only will correlation filters be optimized at declaration time, but they will also be optimized at runtime. Correlation filter matching can be reduced to a hashtable lookup, which aggregates the complexity of the set of defined correlation filters to O(1).

Constructors

CorrelationRuleFilter()	Initializes a new instance of the CorrelationRuleFilter class with default values.
CorrelationRuleFilter(String)	Initializes a new instance of the CorrelationRuleFilter class with the specified correlation identifier.

Properties

ApplicationProperties	Application specific properties of the message.
ContentType	Content type of the message.
CorrelationId	Identifier of the correlation.
MessageId	Identifier of the message.
ReplyTo	Address of the queue to reply to.
ReplyToSessionId	Session identifier to reply to.
SessionId	Session identifier.
Subject	Application specific subject.
To	Address to send to.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object.
Equals(RuleFilter)	Indicates whether the current object is equal to another object of the same type.
GetHashCode()	Serves as the default hash function.
ToString()	Converts the value of the current instance to its equivalent string representation.

Operators

Equality(CorrelationRuleFilter, CorrelationRuleFilter)	Compares two CorrelationRuleFilter values for equality.
Inequality(CorrelationRuleFilter, CorrelationRuleFilter)	Compares two CorrelationRuleFilter values for inequality.
