areEqual

public boolean areEqual(java.util.Calendar one,
                        java.util.Calendar another)

Description copied from class: AbstractTypeDescriptor

Determine if two instances are equal

Specified by:

areEqual in interface JavaTypeDescriptor<java.util.Calendar>

Overrides:

areEqual in class AbstractTypeDescriptor<java.util.Calendar>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(java.util.Calendar value)

Description copied from class: AbstractTypeDescriptor

Extract a proper hash code for this value.

Specified by:

extractHashCode in interface JavaTypeDescriptor<java.util.Calendar>

Overrides:

extractHashCode in class AbstractTypeDescriptor<java.util.Calendar>

Parameters:

value - The value for which to extract a hash code.

Returns:

The extracted hash code.

getComparator

public java.util.Comparator<java.util.Calendar> getComparator()

Description copied from class: AbstractTypeDescriptor

Retrieve the natural comparator for this type.

Specified by:

getComparator in interface JavaTypeDescriptor<java.util.Calendar>

Overrides:

getComparator in class AbstractTypeDescriptor<java.util.Calendar>

Returns:

The natural comparator.

unwrap

public <X> X unwrap(java.util.Calendar value,
                    java.lang.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> java.util.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.
