Class SasTemporalFormatter

java.lang.Object

com.epam.parso.date.SasTemporalFormatter

public class SasTemporalFormatter
extends Object

SAS supports wide family of date formats. This class allows to represent SAS date in various types.

This class is not thread-safe and it should be synchronised externally. Actually, it is not a problem for the the Parso itself as it is a single-threaded library, where each instance of SasFileParser has it's own instance of the formatter.
