All Implemented Interfaces:

Context

Direct Known Subclasses:

AdviceContext, ApiVersionRouterContext, AttributesContext, AuditingContext, AuthRedirectContext, CapturedUserPasswordContext, CdSsoContext, CdSsoFailureContext, ClientContext, HttpContext, InternalSsoTokenContext, JwtBuilderContext, JwtValidationContext, JwtValidationErrorContext, OAuth2Context, OAuth2FailureContext, OAuth2SessionContext, OAuth2TokenExchangeContext, PolicyDecisionContext, RequestAuditContext, RootContext, SecurityContext, SessionContext, SessionInfoContext, SsoTokenContext, StsContext, TransactionIdContext, UriRouterContext, UserProfileContext, WebSocketHandshakeContext
```
public abstract class AbstractContext
extends Object
implements Context
```
A base implementation of the Context interface. Derived Contexts MUST support persistence by providing
- a public constructor having the same declaration as AbstractContext(JsonValue, ClassLoader)
- a public method having the same declaration as Context.toJsonValue()
See the documentation for more details.
Here is an example of the JSON representation of the core attributes of all contexts:
```
 {
   "id"     : "56f0fb7e-3837-464d-b9ec-9d3b6af665c3",
   "class"  : ...Java class name..,
   "parent" : {
       ...
   }
 }
 
```

  - AbstractContext
```
protected AbstractContext(Context parent,
                          String name)
```
    Constructs a new AbstractContext with a null id.
    
    Parameters:
    
    parent - The parent context.
    
    name - The name of the context.
  - AbstractContext
```
protected AbstractContext(String id,
                          String name,
                          Context parent)
```
    Constructs a new AbstractContext.
    
    Parameters:
    
    id - The id of the context.
    
    parent - The parent context.
    
    name - The name of the context.
  - AbstractContext
```
public AbstractContext(JsonValue savedContext,
                       ClassLoader classLoader)
```
    Creates a new context from the JSON representation of a previously persisted context.
    Sub-classes MUST provide a constructor having the same declaration as this constructor in order to support persistence. Implementations MUST take care to invoke the super class implementation before parsing their own context attributes. Below is an example implementation for a security context which stores the user name and password of the authenticated user:
    protected SecurityContext(JsonValue savedContext, ClassLoader classLoader) { // Invoke the super-class implementation first. super(savedContext, classLoader); // Now parse the attributes for this context. this.username = savedContext.get("username").required().asString(); this.password = savedContext.get("password").required().asString(); }
    In order to create a context's persisted JSON representation, implementations must override.
    Parameters:
    
    savedContext - The JSON representation from which this context's attributes should be parsed.
    
    classLoader - The ClassLoader which can properly resolve the persisted class-name.
