Class LatestVersionMatcher

    java.lang.Object

          org.apache.ivy.plugins.version.LatestVersionMatcher

All Implemented Interfaces:
  IvySettingsAware, VersionMatcher

    public class LatestVersionMatcher

extends AbstractVersionMatcher

Constructor Summary
`LatestVersionMatcher()`

Method Summary
`boolean` | `accept(ModuleRevisionId askedMrid, ModuleDescriptor foundMD)` Indicates if this version matcher considers that the module found matches the asked one.
`boolean` | `accept(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid)` Indicates if this version matcher considers that the module revision found matches the asked one.
`int` | `compare(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid, java.util.Comparator staticComparator)` If we don't need a module descriptor we can consider the dynamic revision to be greater.
`boolean` | `isDynamic(ModuleRevisionId askedMrid)` Indicates if the given asked ModuleRevisionId should be considered as dynamic for the current VersionMatcher or not.
`boolean` | `needModuleDescriptor(ModuleRevisionId askedMrid, ModuleRevisionId foundMrid)` Indicates if this VersionMatcher needs module descriptors to determine if a module revision matches the asked one.

Constructor Detail

### LatestVersionMatcher

    public LatestVersionMatcher()

Method Detail

### isDynamic

    public boolean isDynamic(ModuleRevisionId askedMrid)

  Description copied from interface: `VersionMatcher`
  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
  Returns:
    true if this revision is considered as a dynamic one, false otherwise

### accept

    public boolean accept(ModuleRevisionId askedMrid,
                          ModuleRevisionId foundMrid)

  Description copied from interface: `VersionMatcher`
  Indicates if this version matcher considers that the module revision found matches the asked one.

  Returns:

### 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`
  Overrides:
    `needModuleDescriptor` in class `AbstractVersionMatcher`
  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`
  Overrides:
    `accept` in class `AbstractVersionMatcher`
  Returns:

### compare

    public int compare(ModuleRevisionId askedMrid,
                       ModuleRevisionId foundMrid,
                       java.util.Comparator staticComparator)

  If we don't need a module descriptor we can consider the dynamic revision to be greater. If we need a module descriptor then we can't know which one is greater and return 0.

  Specified by:
    `compare` in interface `VersionMatcher`
  Overrides:
    `compare` in class `AbstractVersionMatcher`
  Parameters:
    `askedMrid` - the dynamic revision to compare
    `foundMrid` - the static revision to compare
    `staticComparator` - 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
