 package javax.servlet;
 
 import java.util.*;
Java Class representation of an javax.servlet.annotation.HttpConstraint annotation value.

Since:
Servlet 3.0
 
 public class HttpConstraintElement {
 
     private String[] rolesAllowed;

    
Constructs a default HTTP constraint element
 
     public HttpConstraintElement() {
         this(.);
     }

    
Convenience constructor to establish EmptyRoleSemantic.DENY

Parameters:
semantic should be EmptyRoleSemantic.DENY
 
     public HttpConstraintElement(EmptyRoleSemantic semantic) {
         this(semantic.new String[0]);
     }

    
Constructor to establish non-empty getRolesAllowed and/or TransportGuarantee.CONFIDENTIAL.

Parameters:
guarantee TransportGuarantee.NONE or TransportGuarantee.CONFIDENTIAL
roleNames the names of the roles that are to be allowed access
 
     public HttpConstraintElement(TransportGuarantee guarantee,
             String... roleNames) {
         this(.guaranteeroleNames);
     }

    
Constructor to establish all of getEmptyRoleSemantic, getRolesAllowed, and getTransportGuarantee.

Parameters:
semantic EmptyRoleSemantic.DENY or EmptyRoleSemantic.PERMIT
guarantee TransportGuarantee.NONE or TransportGuarantee.CONFIDENTIAL
roleNames the names of the roles that are to be allowed access, or missing if the semantic is EmptyRoleSemantic.DENY
 
    public HttpConstraintElement(EmptyRoleSemantic semantic,
            TransportGuarantee guaranteeString... roleNames) {
        if (semantic == . && roleNames.length > 0) {
            throw new IllegalArgumentException(
                "Deny semantic with rolesAllowed");
        }
        this. = semantic;
        this. = guarantee;
        this. = roleNames;
    }

    
Gets the default authorization semantic.

This value is insignificant when getRolesAllowed returns a non-empty array, and should not be specified when a non-empty array is specified for getRolesAllowed.

Returns:
the javax.servlet.annotation.ServletSecurity.EmptyRoleSemantic to be applied when getRolesAllowed returns an empty (that is, zero-length) array
        return this.;
    }

    
Gets the data protection requirement (i.e., whether or not SSL/TLS is required) that must be satisfied by the transport connection.

Returns:
the javax.servlet.annotation.ServletSecurity.TransportGuarantee indicating the data protection that must be provided by the connection
        return this.;
    }

    
Gets the names of the authorized roles.

Duplicate role names appearing in getRolesAllowed are insignificant and may be discarded. The String "*" has no special meaning as a role name (should it occur in getRolesAllowed).

Returns:
a (possibly empty) array of role names. When the array is empty, its meaning depends on the value of getEmptyRoleSemantic(). If its value is DENY, and getRolesAllowed returns an empty array, access is to be denied independent of authentication state and identity. Conversely, if its value is PERMIT, it indicates that access is to be allowed independent of authentication state and identity. When the array contains the names of one or more roles, it indicates that access is contingent on membership in at least one of the named roles (independent of the value of getEmptyRoleSemantic()).
    public String[] getRolesAllowed() {
        return this.;
    }
