Method Detail

createTree

public static RepoFileDTOTreeNode createTree(Collection<RepoFileDTO> repoFileDTOs)
                                      throws IllegalArgumentException

Create a single tree from the given repoFileDTOs.

The given repoFileDTOs must meet the following criteria:

• It must not be null.
• It may be empty.
• If it is not empty, it may contain any number of elements, but:
  • It must contain exactly one root-node (with RepoFileDTO.parentEntityID being null).
  • It must resolve completely, i.e. there must be a RepoFileDTO for every referenced parentEntityID.

Parameters:

repoFileDTOs - the DTOs to be organized in a tree structure. Must not be null. If empty, the method result will be null.

Returns:

the tree's root node. null, if repoFileDTOs is empty. Never null, if repoFileDTOs contains at least one element.

Throws:

IllegalArgumentException - if the given repoFileDTOs does not meet the criteria stated above.
