Class VisitNode

java.lang.Object
org.apache.ivy.core.resolve.VisitNode
public class VisitNode extends Object
A visit node is an object used to represent one visit from one parent on an IvyNode of the dependency graph. During dependency resolution, the ResolveEngine visits nodes of the dependency graph following the dependencies, thus the same node can be visited several times, if it is requested from several module. In this case you will have one VisitNode per parent and per root module configuration. Thus VisitNode stores data specific to the visit:
parent
the node from which the visit is occurring
parentConf
the configuration of the parent in which this node is visited
rootModuleConf
the configuration of the root module which is currently resolved

  • Method Details

    • getNode

      public IvyNode getNode()

    • getRequestedConf

      public String getRequestedConf()
      Returns:
      Returns the configuration requested by the parent

    • setRequestedConf

      public void setRequestedConf(String requestedConf)

    • getParent

      public VisitNode getParent()

    • getRoot

      public VisitNode getRoot()

    • getPath

      public Collection<VisitNode> getPath()
      Get an ordered collection with the nodes from the root to this node
      Returns:
      Collection<VisitNode>

    • getParentConf

      public String getParentConf()

    • setParentConf

      public void setParentConf(String parentConf)

    • getRootModuleConf

      public String getRootModuleConf()

    • getRoot

      public static VisitNode getRoot(VisitNode parent)

    • isTransitive

      public boolean isTransitive()
      Returns true if the current dependency descriptor is transitive and the parent configuration is transitive. Otherwise returns false.
      Returns:
      true if current node is transitive and the parent configuration is transitive.

    • isParentConfTransitive

      protected boolean isParentConfTransitive()
      Checks if the current node's parent configuration is transitive.
      Returns:
      true if the node's parent configuration is transitive

    • getRealNode

      public IvyNode getRealNode()
      Returns the 'real' node currently visited. 'Real' means that if we are visiting a node created originally with only a version constraint, and if this version constraint has been resolved to an existing node in the graph, we will return the existing node, and not the one originally used which is about to be discarded, since it's not possible to have in the graph two nodes for the same ModuleRevisionId
      Returns:
      the 'real' node currently visited.

    • useRealNode

      public void useRealNode()
      Ask to the current visited node to use a real node only, if one exist. See getRealNode for details about what a 'real' node is.
