GenAttribute

One attribute use. Prefer the typed GenAttributes.decode<A>() (via attribute<A>() on a node); the positional readers below are what decoders are built from.

public class GenAttribute

public id: string

name

Unqualified attribute name as written, without the @ (json).

public name: string

args

Arguments supplied to the attribute, in declaration order.

public args: List<GenAttrArg>

constructor

public constructor(id: string, name: string, args: List<GenAttrArg>)

string_arg

Argument i as unquoted text, or an empty string when there is no such argument.

public fun string_arg(i: int): string

int_arg

Argument i parsed as an int, or 0 when it is missing or not an integer.

public fun int_arg(i: int): int

long_arg

Argument i parsed as a long, or 0 when it is missing or not an integer.

public fun long_arg(i: int): long

double_arg

Argument i parsed as a double, or 0.0 when it is missing or not a number.

public fun double_arg(i: int): double

float_arg

Argument i parsed as a float, or 0.0 when it is missing or not a number.

public fun float_arg(i: int): float

Whether argument i is the literal true; missing arguments read as false.

public fun bool_arg(i: int): bool

enum_member

The member name of an enum argument (Get for HttpMethod.Get).

public fun enum_member(i: int): string
