Method Summary

Modifier and Type	Method	Description
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, Comparator<ModuleRevisionId> 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.

public LatestVersionMatcher()

Method Details

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.

Parameters:

askedMrid - ModuleRevisionId

foundMrid - ModuleRevisionId

Returns:

boolean

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

Parameters:

askedMrid - ModuleRevisionId

foundMrid - ModuleRevisionId

Returns:

boolean

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

Parameters:

askedMrid - ModuleRevisionId

foundMD - ModuleDescriptor

Returns:

boolean

compare

public int compare(ModuleRevisionId askedMrid,
 ModuleRevisionId foundMrid,
 Comparator<ModuleRevisionId> 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 - ModuleRevisionId

foundMrid - ModuleRevisionId

staticComparator - Comparator

Returns:

int
