ThisParser class

If the function takes an expression as a parameter, the function will evaluate the expression passed for the parameter with respect to each of the items in the input collection. These expressions may refer to the special $this and $index elements, which represent the item from the input collection currently under evaluation, and its index in the collection, respectively. For example, in name.given.where($this > 'ba' and $this < 'bc') the where() function will iterate over each item in the input collection (elements named given) and $this will be set to each item when the expression passed to where() is evaluated.

Properties

hashCode → int
The hash code for this object.

runtimeType → Type
A representation of the runtime type of the object.

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.
inherited
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.
