Constructor Details

WebActionContext

public WebActionContext(org.apache.commons.chain.web.jakarta.WebContext context)

Instantiate this composite by wrapping an instance of WebContext.

Parameters:

context - The WebContext to wrap

Method Details

webContext

protected org.apache.commons.chain.web.jakarta.WebContext webContext()

Provide the wrapped WebContext for this composite.

Returns:

The wrapped WebContext

release

public void release()

Description copied from interface: ActionContext

Signal to the instance that it will not be used any more, so that any resources which should be cleaned up can be cleaned up.

Specified by:

release in interface ActionContext

Overrides:

release in class ActionContextBase

getHeader

public Map<String,String> getHeader()

Return an immutable Map that maps header names to the first (or only) header value (as a String).

Returns:

A immutable Map of web request header names

getHeaderValues

public Map<String,String[]> getHeaderValues()

Return an immutable Map that maps header names to the set of all values specified in the request (as a String array). Header names must be matched in a case-insensitive manner.

Returns:

An immutable Map of web request header values

getInitParam

public Map<String,String> getInitParam()

Return an immutable Map that maps context application initialization parameters to their values.

Returns:

An immutable Map of web context initialization parameters

getParam

public Map<String,String> getParam()

Return a map whose keys are String request parameter names and whose values are String values.

For parameters which were submitted with more than one value, only one value will be returned, as if one called ServletRequest.getParameter(String).

Returns:

A map of web request parameters

getParamValues

public Map<String,String[]> getParamValues()

Return a map whose keys are String request parameter names and whose values are String[] values.

Returns:

A map of web request parameter values (as an array)

getApplicationScope

public Map<String,Object> getApplicationScope()

Description copied from interface: ActionContext

Return a Map of Application scoped values.

This is implemented in analogy with the Application scope in the Servlet API, but it seems reasonable to expect that any Struts implementation will have an equivalent concept.

The ultimate meaning of "application scope" is an implementation detail left unspecified by Struts.

Specified by:

getApplicationScope in interface ActionContext

Specified by:

getApplicationScope in class ActionContextBase

Returns:

A Map of "application scope" attributes.

getRequestScope

public Map<String,Object> getRequestScope()

Description copied from interface: ActionContext

Return a Map of request scoped values. A request is understood as the fundamental motivation for any particular instance of an ActionContext.

This is implemented in analogy with the Request Context in the Servlet API, but it seems reasonable to expect that any Struts implementation will have an equivalent concept.

The ultimate meaning of "request scope" is an implementation detail left unspecified by Struts.

Specified by:

getRequestScope in interface ActionContext

Specified by:

getRequestScope in class ActionContextBase

Returns:

a Map of "request scope" attributes.

getParameterMap

public Map<String,String[]> getParameterMap()

Description copied from interface: ActionContext

Return a Map of parameters submitted by the user as part of this request. The keys to this map will be request parameter names (of type String), and the values will be String[].

This is implemented in analogy with the Request parameters of the Servlet API, but it seems reasonable to expect that any Struts implementation will have an equivalent concept.

Returns:

A map of the request parameter attributes

getSessionScope

public Map<String,Object> getSessionScope()

Description copied from interface: ActionContext

Return a Map of Session scoped values. A session is understood as a sequence of requests made by the same user.

This is implemented in analogy with the Session scope in the Servlet API, but it seems reasonable to expect that any Struts implementation will have an equivalent concept.

The ultimate meaning of "session scope" is an implementation detail left unspecified by Struts.

Specified by:

getSessionScope in interface ActionContext

Specified by:

getSessionScope in class ActionContextBase

Returns:

A Map of "session scope" attributes.

setModuleConfig

public void setModuleConfig(ModuleConfig moduleConfig)

Description copied from interface: ActionContext

Set the ModuleConfig which is operative for the current request.

Specified by:

setModuleConfig in interface ActionContext

Overrides:

setModuleConfig in class ActionContextBase

Parameters:

moduleConfig - The ModuleConfig to be used with this request

getModuleConfig

public ModuleConfig getModuleConfig()

Description copied from interface: ActionContext

Get the ModuleConfig which is operative for the current request.

Specified by:

getModuleConfig in interface ActionContext

Overrides:

getModuleConfig in class ActionContextBase

Returns:

The MooduleConfig being used with this request

See Also:

• ActionContext.getModuleConfig()

setCancelled

public void setCancelled(Boolean cancelled)

Description copied from interface: ActionContext

Set the "cancel event" state for this context.

Specified by:

setCancelled in interface ActionContext

Overrides:

setCancelled in class ActionContextBase

Parameters:

cancelled - On true, set the cancel event state to true. On false, set the cancel event state to false.

See Also:

• ActionContextBase.CANCEL_KEY

getCancelled

public Boolean getCancelled()

Description copied from interface: ActionContext

Indicate if the "cancel event" state is set for for this context,

Specified by:

getCancelled in interface ActionContext

Overrides:

getCancelled in class ActionContextBase

See Also:

• ActionContextBase.CANCEL_KEY
