This class provides advanced methods on enum values. It is ideally used with
using EnumValueTools
and then acts as an
extension to the
EnumValue
types.
If the first argument to any of the methods is null, the result is unspecified.
Static methods
staticinlineequals<T> (a:T, b:T):Bool
Recursively compares two enum instances a
and b
by value.
Unlike a == b
, this function performs a deep equality check on the
arguments of the constructors (if there are any).
If a
or b
are null
, the result is unspecified.
staticinlinegetIndex (e:EnumValue):Int
Returns the index of enum instance e
.
This corresponds to the original syntactic position of e
. The index of
the first declared constructor is 0, the next one is 1 etc.
If e
is null
, the result is unspecified.
staticinlinegetName (e:EnumValue):String
Returns the constructor name of enum instance e
.
The result String does not contain any constructor arguments.
If e
is null
, the result is unspecified.
staticinlinegetParameters (e:EnumValue):Array<Dynamic>
Returns a list of the constructor arguments of enum instance e
.
If e
has no arguments, the result is []
.
Otherwise the result are the values that were used as arguments to e
,
in the order of their declaration.
If e
is null
, the result is unspecified.
staticmatch (e:EnumValue, pattern:Dynamic):Bool
Matches enum instance e
against pattern pattern
, returning true
if
matching succeeded and false
otherwise.
Example usage:
if (e.match(pattern)) {
// codeIfTrue
} else {
// codeIfFalse
}
This is equivalent to the following code:
switch (e) {
case pattern:
// codeIfTrue
case _:
// codeIfFalse
}
This method is implemented in the compiler. This definition exists only for documentation.
