Field Summary

static java.lang.String	TREE_BUILD_EVENT
static java.lang.String	TREE_NODE_BUILD_EVENT

Method Summary

MetadataTreeNode	buildTree(ArtifactBasicMetadata startMD, ArtifactScopeEnum scope) build the tree, using the repositories specified in the constructor
void	register(MercuryEventListener listener) register a listener for dependency events
java.util.List<ArtifactMetadata>	resolveConflicts(MetadataTreeNode root) hard to believe, but this actually resolves the conflicts, removing all duplicate GAVs from the tree
MetadataTreeNode	resolveConflictsAsTree(MetadataTreeNode root) this one resolves the conflicts, removing all duplicate GAVs from the tree and returning a copy of the resulting subtree - original tree should be intact
void	unRegister(MercuryEventListener listener) remove a listener

Method Detail

buildTree

MetadataTreeNode buildTree(ArtifactBasicMetadata startMD,
                           ArtifactScopeEnum scope)
                           throws MetadataTreeException

build the tree, using the repositories specified in the constructor

Parameters:

startMD - - root of the tree to build

targetPlatform - - limitations to use when retrieving metadata. Format is G:A=V, where V is Version Range

Returns:

the root of the tree built

Throws:

MetadataTreeException

resolveConflicts

java.util.List<ArtifactMetadata> resolveConflicts(MetadataTreeNode root)
                                                  throws MetadataTreeException

hard to believe, but this actually resolves the conflicts, removing all duplicate GAVs from the tree

Parameters:

root - the tree to resolve conflicts on

Returns:

list of resolved GAVs

Throws:

MetadataTreeException

resolveConflictsAsTree

MetadataTreeNode resolveConflictsAsTree(MetadataTreeNode root)
                                        throws MetadataTreeException

this one resolves the conflicts, removing all duplicate GAVs from the tree and returning a copy of the resulting subtree - original tree should be intact

Parameters:

root - the tree to resolve conflicts on

Returns:

resolved subtree

Throws:

MetadataTreeException
