Enum Constant Summary

Enum Constants
Enum Constant	Description
`DENOMINATOR`	The lower portion of a fraction used to calculate a rate, proportion, or ratio.
`DENOMINATOREXCEPTION`	Denominator exceptions are conditions that should remove a patient or event from the denominator of a measure only if the numerator criteria are not met.
`DENOMINATOREXCLUSION`	Denominator exclusion criteria define patients or events that should be removed from the denominator before determining if numerator criteria are met.
`INITIALPOPULATION`	The initial population refers to all patients or events to be evaluated by a quality measure involving patients who share a common set of specified characterstics.
`MEASUREOBSERVATION`	Defines the individual observation to be performed for each patient or event in the measure population.
`MEASUREPOPULATION`	Measure population criteria define the patients or events for which the individual observation for the measure should be taken.
`MEASUREPOPULATIONEXCLUSION`	Measure population criteria define the patients or events that should be removed from the measure population before determining the outcome of one or more continuous variables defined for the measure observation.
`NULL`	added to help the parsers
`NUMERATOR`	The upper portion of a fraction used to calculate a rate, proportion, or ratio.
`NUMERATOREXCLUSION`	Numerator exclusion criteria define patients or events to be removed from the numerator.

- Enum Constant Detail
  - INITIALPOPULATION
```
public static final MeasurePopulation INITIALPOPULATION
```
    The initial population refers to all patients or events to be evaluated by a quality measure involving patients who share a common set of specified characterstics. All patients or events counted (for example, as numerator, as denominator) are drawn from the initial population.
  - NUMERATOR
```
public static final MeasurePopulation NUMERATOR
```
    The upper portion of a fraction used to calculate a rate, proportion, or ratio. Also called the measure focus, it is the target process, condition, event, or outcome. Numerator criteria are the processes or outcomes expected for each patient, or event defined in the denominator. A numerator statement describes the clinical action that satisfies the conditions of the measure.
  - NUMERATOREXCLUSION
```
public static final MeasurePopulation NUMERATOREXCLUSION
```
    Numerator exclusion criteria define patients or events to be removed from the numerator. Numerator exclusions are used in proportion and ratio measures to help narrow the numerator (for inverted measures).
  - DENOMINATOR
```
public static final MeasurePopulation DENOMINATOR
```
    The lower portion of a fraction used to calculate a rate, proportion, or ratio. The denominator can be the same as the initial population, or a subset of the initial population to further constrain the population for the purpose of the measure.
  - DENOMINATOREXCLUSION
```
public static final MeasurePopulation DENOMINATOREXCLUSION
```
    Denominator exclusion criteria define patients or events that should be removed from the denominator before determining if numerator criteria are met. Denominator exclusions are used in proportion and ratio measures to help narrow the denominator. For example, patients with bilateral lower extremity amputations would be listed as a denominator exclusion for a measure requiring foot exams.
  - DENOMINATOREXCEPTION
```
public static final MeasurePopulation DENOMINATOREXCEPTION
```
    Denominator exceptions are conditions that should remove a patient or event from the denominator of a measure only if the numerator criteria are not met. Denominator exception allows for adjustment of the calculated score for those providers with higher risk populations. Denominator exception criteria are only used in proportion measures.
  - MEASUREPOPULATION
```
public static final MeasurePopulation MEASUREPOPULATION
```
    Measure population criteria define the patients or events for which the individual observation for the measure should be taken. Measure populations are used for continuous variable measures rather than numerator and denominator criteria.
  - MEASUREPOPULATIONEXCLUSION
```
public static final MeasurePopulation MEASUREPOPULATIONEXCLUSION
```
    Measure population criteria define the patients or events that should be removed from the measure population before determining the outcome of one or more continuous variables defined for the measure observation. Measure population exclusion criteria are used within continuous variable measures to help narrow the measure population.
  - MEASUREOBSERVATION
```
public static final MeasurePopulation MEASUREOBSERVATION
```
    Defines the individual observation to be performed for each patient or event in the measure population. Measure observations for each case in the population are aggregated to determine the overall measure score for the population.
  - NULL
```
public static final MeasurePopulation NULL
```

```
public static MeasurePopulation[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (MeasurePopulation c : MeasurePopulation.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static MeasurePopulation valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - fromCode
```
public static MeasurePopulation fromCode(String codeString)
                                  throws org.hl7.fhir.exceptions.FHIRException
