fromString

public Calendar fromString(String string)

areEqual

public boolean areEqual(Calendar one,
                        Calendar another)
Description copied from class: AbstractTypeDescriptor
Determine if two instances are equal

Specified by:
areEqual in interface JavaTypeDescriptor<Calendar>
Overrides:
areEqual in class AbstractTypeDescriptor<Calendar>
Parameters:
one - One instance
another - The other instance
Returns:
True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(Calendar value)
Description copied from class: AbstractTypeDescriptor

Specified by:
extractHashCode in interface JavaTypeDescriptor<Calendar>
Overrides:
extractHashCode in class AbstractTypeDescriptor<Calendar>
Parameters:
value - The value for which to extract a hash code.
Returns:
The extracted hash code.

getComparator

public Comparator<Calendar> getComparator()
Description copied from class: AbstractTypeDescriptor
Retrieve the natural comparator for this type.

Specified by:
getComparator in interface JavaTypeDescriptor<Calendar>
Overrides:
getComparator in class AbstractTypeDescriptor<Calendar>
Returns:
The natural comparator.

unwrap

public <X> X unwrap(Calendar value,
                    Class<X> type,
                    WrapperOptions options)
Description copied from interface: JavaTypeDescriptor
Unwrap an instance of our handled Java type into the requested type.

As an example, if this is a JavaTypeDescriptor<Integer> and we are asked to unwrap the Integer value as a Long we would return something like Long.valueOf( value.longValue() ).

Intended use is during PreparedStatement binding.

Type Parameters:
X - The conversion type.
Parameters:
value - The value to unwrap
type - The type as which to unwrap
options - The options
Returns:
The unwrapped value.

wrap

public <X> Calendar wrap(X value,
                         WrapperOptions options)
Description copied from interface: JavaTypeDescriptor
Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Type Parameters:
X - The conversion type.
Parameters:
value - The value to wrap.
options - The options
Returns:
The wrapped value.
