DecimalParser class
The Decimal type represents real values in the range (-10^28+1)/10^8 to (10^28-1)/10^8 with a step size of 10^-8. Again, this is FHIRPath's official definition, we use Dart's double, which I believe is the same range as int but with 15 decimal points. FHIRPath's range is defined based on a survey of decimal-value implementations and is based on the most useful lowest common denominator. Implementations can provide support for larger decimals and higher precision, but must provide at least the range and precision defined here. In addition, implementations should use fixed-precision decimal formats to ensure that decimal values are accurately represented

Properties
Methods
-
execute(
List results, Map< String, dynamic> passed) → List -
The iterable, nested function that evaluates the entire FHIRPath
expression one object at a time
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
prettyPrint(
[int indent = 2]) → String -
Uses a rough approximation of reverse polish notation to render the
parsed value of a FHIRPath in a more human readable way than
verbosePrint, while still demonstrating how the expression was parsed
and nested according to this package
override
-
toString(
) → String -
A string representation of this object.
override
-
verbosePrint(
int indent) → String -
To print the entire parsed FHIRPath expression, this includes ALL
of the Parsers that are used in this package by the names used in
this package. These are not always synonymous with the FHIRPath
specification (although they usually are), and include some parser
classes that were created for ease of evaluation but are not included
at all as objects in the official spec. I'm generally going to recommend
that you use prettyPrint instead
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
