/**
* The main Java EE Security API package. This package contains classes and interfaces that span authentication,
* authorization and identity concerns.
*
* EL Support in annotations
*
* This specification supports the use of expression language 3.0 in annotations. This is described in more detail below:
*
* ...Definition annotations
*
* The Java EE Security API features several annotations, with names that end with Definition,
* which, when used, make CDI beans available. For completeness, this concerns the following annotations:
*
*
* - {@link javax.security.enterprise.identitystore.DatabaseIdentityStoreDefinition}
* - {@link javax.security.enterprise.identitystore.LdapIdentityStoreDefinition}
* - {@link javax.security.enterprise.authentication.mechanism.http.BasicAuthenticationMechanismDefinition}
* - {@link javax.security.enterprise.authentication.mechanism.http.CustomFormAuthenticationMechanismDefinition}
* - {@link javax.security.enterprise.authentication.mechanism.http.FormAuthenticationMechanismDefinition}
*
*
* For all attributes of type String on these annotations, Expression Language 3.0 expressions can be used.
* All named CDI beans are available to that expression, as well as the default classes as specified by EL 3.0 for the
* {@link ELProcessor}.
*
*
* Expressions can be either immediate (${} syntax), or deferred (#{} syntax). Immediate
* expressions are evaluated once when the bean instance corresponding to the "...Definition" annotation is actually created.
* Since such beans are application scoped, that means once for the entire application. Deferred expressions are evaluated in
* each request where the security runtime needs to use the value of these attributes.
*
*
* Attributes that are documented as being EL alternatives to non-String type
* attributes (attributes for which the name ends with Expression, hereafter called EL alternative attribute)
* MUST evaluate to the same type as the attribute they are an alternative to. If the EL alternative attribute has a
* non empty value, it takes precedence over the attribute which it is an alternative to.
*
*
* The EL alternative attribute MUST contain a valid EL expression. Attributes of type string that are not EL alternative
* attributes can contain either an expression or a string value that is not an expression.
*
*
Interceptor annotations
*
* The Java EE Security API features several annotations with attributes that denote interceptor spec interceptors.
* For completeness, this concerns the following annotations:
*
*
* - {@link javax.security.enterprise.authentication.mechanism.http.LoginToContinue}
* - {@link javax.security.enterprise.authentication.mechanism.http.RememberMe}
*
*
*
* Expression language is supported for these annotations as well, but in a slightly different way.
* See the javadoc of both these annotations for how the expression language support differs.
*
* @version 1.0
