Constructor Detail

MockExternalContext

public MockExternalContext()

Creates a mock external context with an empty request parameter map. Allows for bean style usage.

MockExternalContext

public MockExternalContext(ParameterMap requestParameterMap)

Creates a mock external context with the specified parameters in the request parameter map. All other properties of the external context can be set using the appropriate setter.

Parameters:

requestParameterMap - the request parameters

Method Detail

getContextPath

public java.lang.String getContextPath()

Description copied from interface: ExternalContext

Returns the logical path to the application hosting this external context.

Specified by:

getContextPath in interface ExternalContext

Returns:

the context path

getRequestParameterMap

public ParameterMap getRequestParameterMap()

Description copied from interface: ExternalContext

Provides access to the parameters associated with the user request that led to SWF being called. This map is expected to be immutable and cannot be changed.

Specified by:

getRequestParameterMap in interface ExternalContext

Returns:

the immutable request parameter map

getRequestMap

public MutableAttributeMap<java.lang.Object> getRequestMap()

Description copied from interface: ExternalContext

Provides access to the external request attribute map, providing a storage for data local to the current user request and accessible to both internal and external SWF artifacts.

Specified by:

getRequestMap in interface ExternalContext

Returns:

the mutable request attribute map

getSessionMap

public SharedAttributeMap<java.lang.Object> getSessionMap()

Description copied from interface: ExternalContext

Provides access to the external session map, providing a storage for data local to the current user session and accessible to both internal and external SWF artifacts.

Specified by:

isResponseAllowed in interface ExternalContext

Returns:

true if yes, false otherwise

isResponseComplete

public boolean isResponseComplete()
