Constructor Detail

DateValue

public DateValue(java.util.Calendar date)
          throws java.lang.IllegalArgumentException

Constructs a DateValue object representing a date.

Parameters:

date - the date this DateValue should represent

Throws:

java.lang.IllegalArgumentException - if the given date cannot be represented as defined by ISO 8601.

Method Detail

valueOf

public static DateValue valueOf(java.lang.String s)
                         throws ValueFormatException

Returns a new DateValue initialized to the value represented by the specified String.

The specified String must be a ISO8601-compliant date/time string.

Parameters:

s - the string to be parsed.

Returns:

a newly constructed DateValue representing the the specified value.

Throws:

ValueFormatException - If the String is not a valid ISO8601-compliant date/time string.

ISO8601

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

The result is true if and only if the argument is not null and is a DateValue object that represents the same value as this object.

The value comparison is performed using the ISO 8601 string representation of the dates, since the native Calendar.equals() method may produce false negatives (see JSR-598).

Note that the comparison still returns false when comparing the same time in different time zones, but that seems to be the intent of JSR 170. Compare the Value.getDate().getTime() values if you need an exact time comparison in UTC.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Returns zero to satisfy the Object equals/hashCode contract. This class is mutable and not meant to be used as a hash key.

Overrides:

hashCode in class java.lang.Object

Returns:

always zero
