VersionComparatorRegistry

public VersionComparatorRegistry()

Create a new VersionComparatorRegistry.

Method Detail

getInstance

public static VersionComparatorRegistry getInstance()

Get the singleton

Returns:

the singleton

removeVersionComparator

public <T,U> void removeVersionComparator(Class<T> t,
                                          Class<U> u)

Remove the version comparator.

Type Parameters:

T - the first version type

U - the second version type

Parameters:

t - first version impl

u - second version impl

removeVersionComparator

public <T> void removeVersionComparator(Class<T> t)

Remove the version comparator.

Type Parameters:

T - the version type

Parameters:

t - version impl

registerVersionComparator

public <T> void registerVersionComparator(Class<T> t,
                                          VersionComparator<T,T> comparator)

Register version comparator. If comparator parameter is null, it's actually a removal.

Type Parameters:

T - the version type

Parameters:

t - version impl

comparator - the version comparator

registerVersionComparator

public <T,U> void registerVersionComparator(Class<T> t,
                                            Class<U> u,
                                            VersionComparator<T,U> comparator)

Register version comparator. If comparator parameter is null, it's actually a removal.

Type Parameters:

T - the first version type

U - the second version type

Parameters:

t - first version impl

u - second version impl

comparator - the version comparator

getComparator

                                                     U u)

Get the comparator.

Type Parameters:

T - the first version type

U - the second version type

Parameters:

t - first version impl

u - second version impl

Returns:

the matching comparator

getComparator

public <T,U> VersionComparator<T,U> getComparator(Class<T> t,
                                                  Class<U> u)

Get the comparator.

Type Parameters:

T - the first version type

U - the second version type

Parameters:

t - first version impl class

u - second version impl class

Returns:

the matching comparator

compare

Returns:

the compare result

same

public <T,U> boolean same(T t,
                          U u)
