unqualify

public static java.lang.String unqualify(java.lang.String qualifiedName)

qualifier

collapse

public static java.lang.String collapse(java.lang.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 java.lang.String collapseQualifier(java.lang.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 java.lang.String partiallyUnqualify(java.lang.String name,
                                                  java.lang.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 java.lang.String collapseQualifierBase(java.lang.String name,
                                                     java.lang.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.

suffix

public static java.lang.String[] suffix(java.lang.String[] columns,
                                        java.lang.String suffix)

Generate a nice alias for the given class name or collection role name and unique integer. Subclasses of Loader do not have to use aliases of this form.

Returns:
