 package javax.servlet;
 
 import java.util.*;
Java Class represntation of a javax.servlet.annotation.ServletSecurity annotation value.

Since:
Servlet 3.0
 
 public class ServletSecurityElement extends HttpConstraintElement {
 
     private Collection<StringmethodNames;
Constructs an instance using the default HttpConstraintElement value as the default Constraint element and with no HTTP Method specific constraint elements.
 
     public ServletSecurityElement() {
          = Collections.emptySet();
     }

    
Constructs an instance with a default Constraint element and with no HTTP Method specific constraint elements.

Parameters:
constraint the HttpConstraintElement to be applied to all HTTP methods other than those represented in the methodConstraints
 
     public ServletSecurityElement(HttpConstraintElement constraint) {
         super(constraint.getEmptyRoleSemantic(),
                 constraint.getTransportGuarantee(),
                 constraint.getRolesAllowed());
          = Collections.emptySet();
     }

    
Constructs an instance using the default HttpConstraintElement value as the default Constraint element and with a collection of HTTP Method specific constraint elements.

Parameters:
methodConstraints the collection of HTTP method specific constraint elements
Throws:
java.lang.IllegalArgumentException if duplicate method names are detected
 
     public ServletSecurityElement(
             Collection<HttpMethodConstraintElementmethodConstraints) {
         this. = (methodConstraints == null ?
             new HashSet<HttpMethodConstraintElement>() : methodConstraints);
          = checkMethodNames(this.);
    }

    
Constructs an instance with a default Constraint element and with a collection of HTTP Method specific constraint elements.

Parameters:
constraint the HttpConstraintElement to be applied to all HTTP methods other than those represented in the methodConstraints
methodConstraints the collection of HTTP method specific constraint elements.
Throws:
java.lang.IllegalArgumentException if duplicate method names are detected
            Collection<HttpMethodConstraintElementmethodConstraints) {
        super(constraint.getEmptyRoleSemantic(),
                constraint.getTransportGuarantee(),
                constraint.getRolesAllowed());
        this. = (methodConstraints == null ?
            new HashSet<HttpMethodConstraintElement>() : methodConstraints);
    }

    
Constructs an instance from a javax.servlet.annotation.ServletSecurity annotation value.

Parameters:
annotation the annotation value
Throws:
java.lang.IllegalArgumentException if duplicate method names are detected
    public ServletSecurityElement(ServletSecurity annotation) {
        super(annotation.value().value(),
                annotation.value().transportGuarantee(),
                annotation.value().rolesAllowed());
        this. = new HashSet<HttpMethodConstraintElement>();
        for (HttpMethodConstraint constraint :
                annotation.httpMethodConstraints()) {
            this..add(
                new HttpMethodConstraintElement(
                    constraint.value(),
                    new HttpConstraintElement(constraint.emptyRoleSemantic(),
                        constraint.transportGuarantee(),
                        constraint.rolesAllowed())));
        }
    }

    
Gets the (possibly empty) collection of HTTP Method specific constraint elements.

If permitted, any changes to the returned Collection must not affect this ServletSecurityElement.

Returns:
the (possibly empty) collection of HttpMethodConstraintElement objects
        return Collections.unmodifiableCollection();
    }

    
Gets the set of HTTP method names named by the HttpMethodConstraints.

If permitted, any changes to the returned Collection must not affect this ServletSecurityElement.

Returns:
the collection String method names
    public Collection<StringgetMethodNames() {
        return Collections.unmodifiableCollection();
    }

    
Checks for duplicate method names in methodConstraints.

Parameters:
methodConstraints
Throws:
java.lang.IllegalArgumentException if duplicate method names are detected
Retrun:
Set of method names
            Collection<HttpMethodConstraintElementmethodConstraints) {
        Collection<StringmethodNames = new HashSet<String>();
        for (HttpMethodConstraintElement methodConstraint :
                        methodConstraints) {
            String methodName = methodConstraint.getMethodName();
            if (!methodNames.add(methodName)) {
                throw new IllegalArgumentException(
                    "Duplicate HTTP method name: " + methodName);
            }
        }
        return methodNames;
    }
