Method Detail

getInstance

public static VersionComparatorRegistry getInstance()

removeVersionComparator

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

Remove the version comparator.

Parameters:

t - first version impl

u - second version impl

removeVersionComparator

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

Remove the version comparator.

Parameters:

t - version impl

registerVersionComparator

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

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

Parameters:

t - version impl

comparator - the version comparator

registerVersionComparator

public <T extends Version,U extends Version> 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.

Parameters:

t - first version impl

u - second version impl

comparator - the version comparator

getComparator

protected <T extends Version,U extends Version> VersionComparator<T,U> getComparator(T t,
                                                                                     U u)

Get the comparator.

Parameters:

t - first version impl

u - second version impl

Returns:

the matching comparator

getComparator

public VersionComparator getComparator(Class<? extends Version> t,
                                       Class<? extends Version> u)

Get the comparator.

Parameters:

t - first version impl class

u - second version impl class

Returns:

the matching comparator

compare

public <T extends Version,U extends Version> int compare(T t,
                                                         U u)

Compare two version impls.

Parameters:

t - T version impl

u - U version impl

Returns:

the compare result
