/**
|
* An entry, comprising of a distinguished name and zero or more attributes.
|
* <p>
|
* Some methods require a schema in order to decode their parameters (e.g.
|
* {@link #addAttribute(String, Object...)} and {@link #setName(String)}). In
|
* these cases the default schema is used unless an alternative schema is
|
* specified in the {@code Entry} constructor. The default schema is not used
|
* for any other purpose. In particular, an {@code Entry} will permit attributes
|
* to be added which have been decoded using multiple schemas.
|
* <p>
|
* Full LDAP modify semantics are provided via the {@link #addAttribute},
|
* {@link #removeAttribute}, and {@link #replaceAttribute} methods.
|
* <p>
|
* Implementations should specify any constraints or special behavior.
|
* Specifically:
|
* <ul>
|
* <li>Which methods are supported.
|
* <li>The order in which attributes are returned using the
|
* {@link #getAllAttributes()} method.
|
* <li>How existing attributes are modified during calls to
|
* {@link #addAttribute}, {@link #removeAttribute}, and
|
* {@link #replaceAttribute} and the conditions, if any, where a reference to
|
* the passed in attribute is maintained.
