SecurityConstraint (Apache Tomcat 10.1.48 API Documentation)
Description: declaration: package: org.apache.tomcat.util.descriptor.web, class: SecurityConstraint

# Class SecurityConstraint

java.lang.Object
org.apache.tomcat.util.descriptor.web.XmlEncodingBase
org.apache.tomcat.util.descriptor.web.SecurityConstraint

All Implemented Interfaces:
  `Serializable`

public class SecurityConstraint extends XmlEncodingBase implements Serializable
Representation of a security constraint element for a web application, as represented in a `<security-constraint>` element in the deployment descriptor.

WARNING: It is assumed that instances of this class will be created and modified only within the context of a single thread, before the instance is made visible to the remainder of the application. After that, only read access is expected. Therefore, none of the read and write access within this class is synchronized.

    Set the user data constraint for this security constraint.
    Parameters:
      `userConstraint` - The new user data constraint

  - ### treatAllAuthenticatedUsersAsApplicationRole

    public void treatAllAuthenticatedUsersAsApplicationRole()
