SecurityConstraint

• java.lang.Object

Fields Summary
private boolean	allRoles Was the "all roles" wildcard included in the authorization constraints for this security constraint?
private boolean	authConstraint Was an authorization constraint included in this security constraint? This is necessary to distinguish the case where an auth-constraint with no roles (signifying no direct access at all) was requested, versus a lack of auth-constraint which implies no access control checking.
private String[]	authRoles The set of roles permitted to access resources protected by this security constraint.
private SecurityCollection[]	collections The set of web resource collections protected by this security constraint.
private String	displayName The display name of this security constraint.
private String	userConstraint The user data constraint for this security constraint. Must be NONE, INTEGRAL, or CONFIDENTIAL.

Constructors Summary
public SecurityConstraint() Construct a new security constraint instance with default values. super();

Methods Summary
public void	addAuthRole(java.lang.String authRole) Add an authorization role, which is a role name that will be permitted access to the resources protected by this security constraint. param authRole Role name to be added if (authRole == null) return; if ("*".equals(authRole)) { allRoles = true; return; } String results[] = new String[authRoles.length + 1]; for (int i = 0; i < authRoles.length; i++) results[i] = authRoles[i]; results[authRoles.length] = authRole; authRoles = results; authConstraint = true;
public void	addCollection(SecurityCollection collection) Add a new web resource collection to those protected by this security constraint. param collection The new web resource collection if (collection == null) return; SecurityCollection results[] = new SecurityCollection[collections.length + 1]; for (int i = 0; i < collections.length; i++) results[i] = collections[i]; results[collections.length] = collection; collections = results;
public boolean	findAuthRole(java.lang.String role) Return true if the specified role is permitted access to the resources protected by this security constraint. param role Role name to be checked if (role == null) return (false); for (int i = 0; i < authRoles.length; i++) { if (role.equals(authRoles[i])) return (true); } return (false);
public java.lang.String[]	findAuthRoles() Return the set of roles that are permitted access to the resources protected by this security constraint. If none have been defined, a zero-length array is returned (which implies that all authenticated users are permitted access). return (authRoles);
public SecurityCollection	findCollection(java.lang.String name) Return the web resource collection for the specified name, if any; otherwise, return null. param name Web resource collection name to return if (name == null) return (null); for (int i = 0; i < collections.length; i++) { if (name.equals(collections[i].getName())) return (collections[i]); } return (null);
public SecurityCollection[]	findCollections() Return all of the web resource collections protected by this security constraint. If there are none, a zero-length array is returned. return (collections);
public boolean	getAllRoles() Was the "all roles" wildcard included in this authentication constraint? // ------------------------------------------------------------- Properties return (this.allRoles);
public boolean	getAuthConstraint() Return the authorization constraint present flag for this security constraint. return (this.authConstraint);
public java.lang.String	getDisplayName() Return the display name of this security constraint. return (this.displayName);
public java.lang.String	getUserConstraint() Return the user data constraint for this security constraint. return (userConstraint);
public boolean	included(java.lang.String uri, java.lang.String method, boolean caseSensitiveMapping) Return true if the specified context-relative URI (and associated HTTP method) are protected by this security constraint. param uri Context-relative URI to check param method Request method being used // END SJSWS 6324431 // We cannot match without a valid request method if (method == null) return (false); // Check all of the collections included in this constraint for (int i = 0; i < collections.length; i++) { if (!collections[i].findMethod(method)) continue; String patterns[] = collections[i].findPatterns(); for (int j = 0; j < patterns.length; j++) { /* SJSWS 6324431 if (matchPattern(uri, patterns[j])) */ // START SJSWS 6324431 if (matchPattern(uri, patterns[j], caseSensitiveMapping)) // END SJSWS 6324431 return (true); } } // No collection included in this constraint matches this request return (false);
private boolean	matchPattern(java.lang.String path, java.lang.String pattern, boolean caseSensitiveMapping) Does the specified request path match the specified URL pattern? This method follows the same rules (in the same order) as those used for mapping requests to servlets. param path Context-relative request path to be checked (must start with '/') param pattern URL pattern to be compared against // END SJSWS 6324431 // Normalize the argument strings if ((path == null) || (path.length() == 0)) path = "/"; if ((pattern == null) || (pattern.length() == 0)) pattern = "/"; // START SJSWS 6324431 if (!caseSensitiveMapping) { path = path.toLowerCase(); pattern = pattern.toLowerCase(); } // END SJSWS 6324431 // Check for exact match if (path.equals(pattern)) return (true); // Check for path prefix matching if (pattern.startsWith("/") && pattern.endsWith("/*")) { pattern = pattern.substring(0, pattern.length() - 2); if (pattern.length() == 0) return (true); // "/*" is the same as "/" if (path.endsWith("/")) path = path.substring(0, path.length() - 1); while (true) { if (pattern.equals(path)) return (true); int slash = path.lastIndexOf('/"); if (slash <= 0) break; path = path.substring(0, slash); } return (false); } // Check for suffix matching if (pattern.startsWith("*.")) { int slash = path.lastIndexOf('/"); int period = path.lastIndexOf('."); if ((slash >= 0) && (period > slash) && path.endsWith(pattern.substring(1))) { return (true); } return (false); } // Check for universal mapping if (pattern.equals("/")) return (true); return (false);
public void	removeAuthRole(java.lang.String authRole) Remove the specified role from the set of roles permitted to access the resources protected by this security constraint. param authRole Role name to be removed if (authRole == null) return; int n = -1; for (int i = 0; i < authRoles.length; i++) { if (authRoles[i].equals(authRole)) { n = i; break; } } if (n >= 0) { int j = 0; String results[] = new String[authRoles.length - 1]; for (int i = 0; i < authRoles.length; i++) { if (i != n) results[j++] = authRoles[i]; } authRoles = results; }
public void	removeCollection(SecurityCollection collection) Remove the specified web resource collection from those protected by this security constraint. param collection Web resource collection to be removed if (collection == null) return; int n = -1; for (int i = 0; i < collections.length; i++) { if (collections[i].equals(collection)) { n = i; break; } } if (n >= 0) { int j = 0; SecurityCollection results[] = new SecurityCollection[collections.length - 1]; for (int i = 0; i < collections.length; i++) { if (i != n) results[j++] = collections[i]; } collections = results; }
public void	setAuthConstraint(boolean authConstraint) Set the authorization constraint present flag for this security constraint. this.authConstraint = authConstraint;
public void	setDisplayName(java.lang.String displayName) Set the display name of this security constraint. this.displayName = displayName;
public void	setUserConstraint(java.lang.String userConstraint) Set the user data constraint for this security constraint. param userConstraint The new user data constraint if (userConstraint != null) this.userConstraint = userConstraint;
public java.lang.String	toString() Return a String representation of this security constraint. StringBuffer sb = new StringBuffer("SecurityConstraint["); for (int i = 0; i < collections.length; i++) { if (i > 0) sb.append(", "); sb.append(collections[i].getName()); } sb.append("]"); return (sb.toString());
