Items
- domain
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Domain of the metric. It denotes objects that should be considered by the metric.
- selection
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Determines whether the object is "selected" by the metric. Default (if the value is computed): true if value greater than 0, false otherwise.
- valueExpression
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  An expression providing the value for the metric. Input: - processedObject: ProcessedObject Output: - any number: the output Default (if the expression is not present but selection criteria is): 1 if selected, 0 otherwise.
