%iKnow.Metrics.Metric

SQL Table Name: %iKnow_Metrics.Metric

The %iKnow.Metrics infrastructure is deprecated in favour of the more SQL-oriented approach offered through %iKnow.Tables.Utils, where you can add computed fields at different levels and choose whether they need to be persisted or not.

This class represents custom metric definitions in your iKnow domain, which express a particular metric of interest for your applications. If you are manually setting individual values, you can instantiate and work with this class directly as follows:

  1. Create a Metric object using %New() and save it using %Save()
  2. Register one or more target types using AddTargetType()
  3. Set and retrieve individual values using GetValue() and SetValue().

Please refer to %iKnow.Metrics.MetricDefinition for a more declarative way of defining and managing custom metrics. and %iKnow.Metrics.MetricBuilder for more coordinated ways to calculate metric values. Using this class directly is not recommended.

See also %iKnow.Metrics.MetricAPI for more functionality and queries.

Methods

method BuildIndices() as %Status
Builds all indices for target types supported by this metric.
method ClearValues(pTargets As %List = "") as %Status
Erases any existing values for this metric, optionally restricted to a particular (set of) targets.
method GetValue(pTargetType As %String, pTargetId As %Integer, pContext As %String = "") as %Numeric

Returns the value of a particular "target" element identified by pTargetId (for example, when pTargetType = $$$IKMTRENTITY, pTargetId is a unique entity ID).

When Type '= $$$IKMTRTYPEDOMAIN, pContext is mandatory and should be a source ID for $$$IKMTRTYPESOURCE or a metadata value for $$$IKMTRTYPEGROUP.

method SetValue(pTargetType As %String, pTargetId As %Integer, pValue As %Integer, pContext As %String = "") as %Status

Sets the value of a particular "target" element identified by pTargetId (for example, when pTargetType = $$$IKMTRENTITY, pTargetId is a unique entity ID) to pValue.

When Type '= $$$IKMTRTYPEDOMAIN, pContext is mandatory and should be a source ID for $$$IKMTRTYPESOURCE or a metadata value for $$$IKMTRTYPEGROUP.
