Uses of TransformOperator in org.openmrs.logic.op

Classes in org.openmrs.logic.op that implement TransformOperator

Modifier and Type	Class and Description
class	Average The Average operator will calculate the average result from a collection of result returned by the logic expression Example: - logicService.parse("'CD4 COUNT'").average(); The above will give us a criteria to get the average result of the "CD4 COUNT" observations
class	Count The Count operator will return the number of results returned by the logic service Example: - logicService.parse("EncounterDataSource.ENCOUNTER_KEY").count(); The above will give us a criteria to get the number of encounter type we have in the system
class	Distinct The Distinct operator will filter out duplicate results and return a set of distinct results.
class	Exists The Exists operator test whether a criteria will exist for person or not.
class	First The First operator will return a subset result of the entire result returned by the criteria Example: - logicService.parse("'CD4 COUNT'").first(2); The above will give us a criteria to get the first two "CD4 COUNT" observations
class	Last The Last operator will return a subset result of the entire result returned by the criteria.
class	NotExists The NotExists operator test whether a criteria will exist for person or not.
