Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	ConflictResolver.ConflictContext A context used to hold information that is relevant for resolving version and scope conflicts.
static class	ConflictResolver.ConflictItem A conflicting dependency.
static class	ConflictResolver.OptionalitySelector An extension point of ConflictResolver that determines the effective optional flag of a dependency from a potentially conflicting set of derived optionalities.
static class	ConflictResolver.ScopeContext A context used to hold information that is relevant for deriving the scope of a child dependency.
static class	ConflictResolver.ScopeDeriver An extension point of ConflictResolver that determines the scope of a dependency in relation to the scope of its parent.
static class	ConflictResolver.ScopeSelector An extension point of ConflictResolver that determines the effective scope of a dependency from a potentially conflicting set of derived scopes.
static class	ConflictResolver.VersionSelector An extension point of ConflictResolver that determines the winner among conflicting dependencies.

Modifier and Type	Field and Description
static String	CONFIG_PROP_VERBOSE The key in the repository session's configuration properties used to store a Boolean flag controlling the transformer's verbose mode.
static String	NODE_DATA_ORIGINAL_OPTIONALITY The key in the dependency node's custom data under which the optional flag of the dependency before derivation and conflict resolution is stored.
static String	NODE_DATA_ORIGINAL_SCOPE The key in the dependency node's custom data under which the scope of the dependency before scope derivation and conflict resolution is stored.
static String	NODE_DATA_WINNER The key in the dependency node's custom data under which a reference to the DependencyNode which has won the conflict is stored.
