Namespace: PostSharp.Patterns.Diagnostics.Transactions.Model

Assembly: PostSharp.Patterns.Diagnostics.Configuration.dll

Syntax

public static class TransactionPolicyExpressionFunctions

Remarks

The if and sample expressions are interpreted by Dynamic Expresso, an expression engine that emulates C#. Call these functions without the class name, for example Matches(t.Request.Path, "^/invoices"). Matches(string, string) is available in both expressions, while the sampling functions Random(double) and OnceEveryXSeconds(double, string) are available only in the sample expression and in extended expressions evaluated with AllowSamplingFunctions.

Methods

Name	Description
Matches(string, string)	Returns `true` if the string `input` matches the regex `pattern`.
OnceEveryXSeconds(double, string)	Returns `true` if the method has not returned `true` for the same key for a period of time.
Random(double)	Returns `true` randomly, with a chance given by the threshold.
