java.util.AbstractMap<K,V>

java.util.HashMap<java.lang.Object,java.lang.Object>

oracle.adf.model.adapter.AdapterContext

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.Object,java.lang.Object>

Direct Known Subclasses:

DTContext

public class AdapterContext
extends java.util.HashMap<java.lang.Object,java.lang.Object>

Defines the context for an adapter.Adapters can get the information like request, connection informstion etc from this context.

Design time context is derived from this context class. Design time context stores or overrides information that are relevant for the design time only.

Constant Field Values

Constructor Detail

AdapterContext

public AdapterContext()

Creates an empty context.

AdapterContext

public AdapterContext(BindingContext ctx)

Creates an context from a binding context. The common runtime will use this constructor to create the execution context.

Parameters:

ctx - The binding context for the application.

Method Detail

getDefaultContext

public static AdapterContext getDefaultContext()

setCurrentContextImpl

public static void setCurrentContextImpl(DTContext impl)

Sets the current design time implementation of this class.

getConnectionContext

public javax.naming.Context getConnectionContext()
                                          throws java.lang.Exception

Gets the context for the connections. Connections that are created at the design time can be retrieved by looking up the conext returned by this method. The connection context will be created from the ADFContext.

Returns:

the read-only initial context.

Throws:

java.lang.Exception

getBindingContext

public BindingContext getBindingContext()

Gets the binding context associated with this context.

Returns:

the binding context. If not available returns null.

getLogger

public oracle.adf.share.logging.ADFLogger getLogger()

Returns the logger for this context.

getResourceStream

public java.io.InputStream getResourceStream(java.lang.String loc)

Creates the InputStream for the given resource location. It uses SmartURL to build the URL for the given location. In case, the given location isn't a valid URL, then ClassLoader is used to fetch the InputStream.

Parameters:

loc - location for the resource

Returns:

InputStream for the resource

getResourceStream

public java.io.InputStream getResourceStream(java.lang.String loc,
                                             AuthenticationScheme authScheme)

Creates the input stream from the resource using authentication information. This api should be used only when the resource is secured.

Parameters:

loc - Resource location

authScheme - Authentication details that was typically fetched from the Connection.

Returns:

InputStream from resource.

getFileURL

public java.net.URL getFileURL(java.lang.String loc)

Creates a file URL based on Location.

Parameters:

loc -

Returns:

getURL

public java.net.URL getURL(java.lang.String urlString)

Creates a URL based on url String. The method first tries to create URL, using URL(String) constructor. If creation of URL, fails URL is created based on getFileURL(urlString)

Parameters:

urlString, - to be used for creation of URL

Returns:

created URL, null, if fails to create the url
