Advanced properties

When querying through EOL, we can access several extra properties on any model element:

• eAllContents: collection with all the model elements directly or indirectly contained within this one.
• eContainer: returns the model element that contains this one, or null if it does not have a container.
• eContents: collection with all the model elements directly contained within this one.
• hawkFile: string with the repository paths of the files that this model element belongs to, separated by ";".
• hawkFiles: collection with the repository paths of all the files that this model element belongs to.
• hawkIn: collection with all the model elements accessible through incoming references.
• hawkInEdges: collection with all the incoming references (see their attributes below).
• hawkNodeId: (since 2.3.0) raw ID of the underlying graph node.
• hawkOut: collection with all the model elements accessible through outgoing references.
• hawkOutEdges: collection with all the outgoing references (see their attributes below).
• hawkProxies: collection with all the proxy reference lists (see their properties below).
• hawkRepo: string with the URLs of the repositories that this model element belongs to, separated by ";".
• hawkRepos: collection with all the repositories that this model element belongs to.
• hawkURIFragment: URI fragment of the model element within its file.

There is also the isContainedWithin(repo, path) method for checking if an element is directly or indirectly contained within a certain file.

References

References are wrapped into entities of their own, with the following attributes:

• edge: raw edge, without wrapping.
• type / name: name of the reference.
• source / startNode: source of the reference.
• target / endNode: target of the reference.

Proxy reference lists

A proxy reference list represents all the unresolved links from a node to the elements in a certain file. These links may be unresolved as the file may be missing, or the specific elements may not be in the file. Proxy reference lists have the following fields:

• sourceNodeID: unique ID of the source model element node for these proxy references.
• targetFile: returns an object which refers to the target file. This object has several fields:
  • repositoryURL: string with URL of the repository that should have this file.
  • filePath: string with path within the repository for the file.
• references: returns a collection with each of the proxy references to the missing file. Each reference has the following fields:
  • edgeLabel: name of the proxy reference.
  • isContainment: true if and only if the proxy reference is a containment reference (the target is contained within the source).
  • isContainer: true if and only if the proxy reference is a container reference (the source is contained within the target).
  • target: object which refers to the target of the proxy reference. This object has several fields:
    • repositoryURL: string with URL of the repository that should have this file.
    • filePath: string with path within the repository for the file.
    • fragment: string with the fragment that identifies the model element within the file.
    • isFragmentBased: true if and only if the proxy reference is purely fragment-based (file path is irrelevant). This can be the case for some modelling technologies (e.g. Modelio).
