Method Details

attempt

public static CastAttempt<DateTime> attempt(Object object)

Tests to see if the value can be cast. Returns a CastAttempt<T> which will contain the result if casting was was successfull, or can be interogated to proceed otherwise.

Parameters:

object - The value to cast

Returns:

The value

attempt

public static CastAttempt<DateTime> attempt(Object object,
 IBoxContext context)

Tests to see if the value can be cast. Returns a CastAttempt<T> which will contain the result if casting was was successfull, or can be interogated to proceed otherwise.

Parameters:

object - The value to cast

Returns:

The value

cast

public static DateTime cast(Object object)

Used to cast anything, throwing exception if we fail

Parameters:

object - The value to cast

Returns:

The value

cast

public static DateTime cast(Object object,
 IBoxContext context)

Used to cast anything, throwing exception if we fail

Parameters:

object - The value to cast

Returns:

The value

cast

public static DateTime cast(Object object,
 Boolean fail,
 IBoxContext context)

Used to cast anything

Parameters:

object - The value to cast

fail - True to throw exception when failing.

Returns:

The value, or null when cannot be cast

cast

public static DateTime cast(Object object,
 Boolean fail,
 ZoneId timezone,
 IBoxContext context)

Used to cast anything to a DateTime object. We start off by testing the object against commonly known Java date objects, and then try to parse the object as a string. If we fail, we return null.

Parameters:

object - The value to cast

fail - True to throw exception when failing.

timezone - The ZoneId to ensure a timezone is applied

Returns:

The value, or null when cannot be cast

cast

public static DateTime cast(Object object,
 Boolean fail,
 ZoneId timezone,
 Boolean clone,
 IBoxContext context)

Used to cast anything to a DateTime object. We start off by testing the object against commonly known Java date objects, and then try to parse the object as a string. If we fail, we return null.

Parameters:

object - The value to cast

fail - True to throw exception when failing.

timezone - The ZoneId to ensure a timezone is applied

clone - If true, will return a clone of the object if it was originally a DateTime.

Returns:

The value, or null when cannot be cast

isKnownDateClass

public static boolean isKnownDateClass(Object object)

This is not meant as a cast or instance of check really-- just a conveneince method of known date classes to differentiate a variable that could possibly be cast to a date (like) a string from a variable which is ALREADY an instance of a specific date class. If this method returns true for an object, that means it SHOULD successfully cast to a DateTime

Parameters:

object - The object to check

Returns:

True if the object is a known date class
