AbstractVersionMatcher
public AbstractVersionMatcher()
AbstractVersionMatcher
public AbstractVersionMatcher(java.lang.String name)
getName
public java.lang.String getName()
- Description copied from interface:
VersionMatcher
- Returns the version matcher name identifying this version matcher
- Specified by:
getName
in interface VersionMatcher
- Returns:
- the version matcher name identifying this version matcher
setName
public void setName(java.lang.String name)
needModuleDescriptor
public boolean needModuleDescriptor(ModuleRevisionId askedMrid,
ModuleRevisionId foundMrid)
- Description copied from interface:
VersionMatcher
- Indicates if this VersionMatcher needs module descriptors to determine if a module revision
matches the asked one. Note that returning true in this method may imply big performance
issues.
- Specified by:
needModuleDescriptor
in interface VersionMatcher
- Returns:
accept
public boolean accept(ModuleRevisionId askedMrid,
ModuleDescriptor foundMD)
- Description copied from interface:
VersionMatcher
- Indicates if this version matcher considers that the module found matches the asked one. This
method can be called even needModuleDescriptor(ModuleRevisionId askedMrid, ModuleRevisionId
foundMrid) returns false, so it is required to implement it in any case, a usual default
implementation being: return accept(askedMrid, foundMD.getResolvedModuleRevisionId());
- Specified by:
accept
in interface VersionMatcher
- Returns:
compare
public int compare(ModuleRevisionId askedMrid,
ModuleRevisionId foundMrid,
java.util.Comparator staticComparator)
- This method should be overriden in most cases, because it uses the default contract to return
1 when it's not possible to know which revision is greater.
- Specified by:
compare
in interface VersionMatcher
- Parameters:
askedMrid
- the dynamic revision to comparefoundMrid
- the static revision to comparestaticComparator
- a comparator which can be used to compare static revisions
- Returns:
- 0 if it's not possible to know which one is greater, greater than 0 if askedMrid
should be considered greater, lower than 0 if it can't be consider greater
