All known Subclasses: org.apache.ivy.plugins.version.AbstractVersionMatcher,
| VersionMatcher | | public interface VersionMatcher (Code) | | This interface defines a version matcher, i.e. a class able to tell if the revision asked by a
module for a dependency is dynamic (i.e. need to find all revisions to find the good one among
them) and if a found revision matches the asked one. Two ways of matching are possible: - based
on the module revision only (known as ModuleRevisionId) - based on the parsed module descriptor
The second being much more time consuming than the first, the version matcher should tell if it
needs such parsing or not using the needModuleDescriptor(ModuleRevisionId askedMrid,
ModuleRevisionId foundMrid) method. Anyway, the first way is always used, and if a revision is
not accepted using the first method, the module descriptor won't be parsed. Therefore if a
version matcher uses only module descriptors to accept a revision or not it should always return
true to needModuleDescriptor(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid) and
accept(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid).
|
| accept | | public boolean accept(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid)(Code) | | Indicates if this version matcher considers that the module revision found matches the asked
one.
Parameters:
askedMrid -
Parameters:
foundMrid - |
| accept | | public boolean accept(ModuleRevisionId askedMrid, ModuleDescriptor foundMD)(Code) | | 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());
Parameters:
askedMrid -
Parameters:
foundMD - |
| compare | | public int compare(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid, Comparator staticComparator)(Code) | | Compares a dynamic revision (askedMrid) with a static one (foundMrid) to indicate which one
should be considered the greater. If there is not enough information to know which one is the
greater, the dynamic one should be considered greater and this method should return 0. This
method should never be called with a askdeMrid for which isDynamic returns false.
Parameters:
askedMrid - the dynamic revision to compare
Parameters:
foundMrid - the static revision to compare
Parameters:
staticComparator - a comparator which can be used to compare static revisions 0 if it's not possible to know which one is greater, greater than 0 if askedMridshould be considered greater, lower than 0 if it can't be consider greater |
| getName | | public String getName()(Code) | | Returns the version matcher name identifying this version matcher
the version matcher name identifying this version matcher |
| isDynamic | | public boolean isDynamic(ModuleRevisionId askedMrid)(Code) | | Indicates if the given asked ModuleRevisionId should be considered as dynamic for the current
VersionMatcher or not.
Parameters:
askedMrid - the dependency module revision id as asked by a module true if this revision is considered as a dynamic one, false otherwise |
| needModuleDescriptor | | public boolean needModuleDescriptor(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid)(Code) | | 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.
