Method Detail

canHandle

public boolean canHandle(java.lang.String selector)

Specified by:

canHandle in interface VersionMatcher

accept

public boolean accept(java.lang.String selector,
                      java.lang.String candidate)

Description copied from interface: VersionMatcher

Indicates if the given version selector matches the given candidate version.

Specified by:

accept in interface VersionMatcher

compare

public int compare(java.lang.String selector,
                   java.lang.String candidate)

Compares a static selector with a candidate version. Algorithm is inspired by PHP version_compare one. TODO: compare() is inconsistent with accept(), because not everything that compares equal is accepted (e.g. 1.0 vs. 1_0). Can this cause problems?
