    • collapse

      public static String collapse(String name)
      Collapses a name. Mainly intended for use with classnames, where an example might serve best to explain. Imagine you have a class named 'org.hibernate.util.StringHelper'; calling collapse on that classname will result in 'o.h.u.StringHelper'.
      Parameters:
      name - The name to collapse.
      Returns:
      The collapsed name.

    • collapseQualifier

      public static String collapseQualifier(String qualifier, boolean includeDots)
      Given a qualifier, collapse it.
      Parameters:
      qualifier - The qualifier to collapse.
      includeDots - Should we include the dots in the collapsed form?
      Returns:
      The collapsed form.

    • partiallyUnqualify

      public static String partiallyUnqualify(String name, String qualifierBase)
      Partially unqualifies a qualified name. For example, with a base of 'org.hibernate' the name 'org.hibernate.util.StringHelper' would become 'util.StringHelper'.
      Parameters:
      name - The (potentially) qualified name.
      qualifierBase - The qualifier base.
      Returns:
      The name itself, or the partially unqualified form if it begins with the qualifier base.

    • collapseQualifierBase

      public static String collapseQualifierBase(String name, String qualifierBase)
      Cross between collapse(java.lang.String) and partiallyUnqualify(java.lang.String, java.lang.String). Functions much like collapse(java.lang.String) except that only the qualifierBase is collapsed. For example, with a base of 'org.hibernate' the name 'org.hibernate.util.StringHelper' would become 'o.h.util.StringHelper'.
      Parameters:
      name - The (potentially) qualified name.
      qualifierBase - The qualifier base.
      Returns:
      The name itself if it does not begin with the qualifierBase, or the properly collapsed form otherwise.
