Classes

ConvertsToBooleanParser

http://hl7.org/fhirpath/#convertstoboolean-boolean If the input collection contains a single item, this function will return true if: the item is a Boolean the item is an Integer that is equal to one of the possible integer representations of Boolean values the item is a Decimal that is equal to one of the possible decimal representations of Boolean values the item is a String that is equal to one of the possible string representations of Boolean values

ConvertsToDateParser

Checks if input can be converted to a Date

ConvertsToDateTimeParser

Checks if input can be converted to a FhirDateTime

ConvertsToDecimalParser

Checks if input can be converted into a Decimal

ConvertsToIntegerParser

Checks if input can be converted to an Integer

ConvertsToQuantityParser

Checks if input can be converted to a ValidatedQuantity

ConvertsToStringParser

Checks if input can be converted to a String

ConvertsToTimeParser

Checks if input can be converted to a Time

IifParser

http://hl7.org/fhirpath/#iifcriterion-expression-true-result-collection-otherwise-result-collection-collection The iif function in FHIRPath is an immediate if, also known as a conditional operator (such as C’s ? : operator). The criterion expression is expected to evaluate to a Boolean. See: http://hl7.org/fhirpath/#singleton-evaluation-of-collections for rules of Boolean evaluation. Any collection with a single non-boolean item is true.

ToBooleanParser

http://hl7.org/fhirpath/#toboolean-boolean If the input collection contains a single item, this function will return a single boolean if: the item is a Boolean the item is an Integer and is equal to one of the possible integer representations of Boolean values the item is a Decimal that is equal to one of the possible decimal representations of Boolean values the item is a String that is equal to one of the possible string representations of Boolean values If the item is not one the above types, or the item is a String, Integer, or Decimal, but is not equal to one of the possible values convertible to a Boolean, the result is empty.

ToQuantityParser
