Method Details

execute

public abstract Object execute(Object value)

executeIntOrThrow

public final int executeIntOrThrow(Object value)

The node by definition should return a double value (that has integer properties), but in some cases we know that the result needs to fit into an integer. Methods like https://tc39.es/proposal-temporal/#sec-temporal-isodatetimewithinlimits or https://tc39.es/proposal-temporal/#sec-temporal-isoyearmonthwithinlimits ensure that days and months are in valid ranges, and years up to about 273,000 years.
