com.ibm.portal.state.accessors.portlet
Interface PortletAccessor

All Superinterfaces:

Accessor, Disposable, Identifiable

All Known Subinterfaces:

LegacyPortletAccessor, LegacyPortletAccessorController, PortletAccessorController

public interface PortletAccessor
extends Identifiable, Accessor

Interface providing read-only accessor methods which allow for inspecting state information related to the portlet this accessor operates on, in particular portlet mode, window state, and render parameters.
Note that this accessor is suitable for legacy portlets as well as standard portlets.
Any implementation of this interface should ensure that also the return types (e.g. the render parameter map) are not modifiable.

Since:

5.1

Method Detail

getDigest

java.lang.String getDigest()

Returns a string that represents a hash over the representation of the portlet window for its current navigational state.

Returns:

the hash string for this portlet, can be null if the digest could not be computed

Since:

8.0

getParameters

java.util.Map<java.lang.String,java.lang.String[]> getParameters()

Returns a map of portlet parameters (String -> String[]). If no render parameters can be found, an empty map is returned. Note that it is not guaranteed that the returned map is modifiable.

Returns:

Map of render parameters (potentially unmodifiable). If there are no render parameters at all, an empty map is returned. Does not return null.

getPortletMode

javax.portlet.PortletMode getPortletMode()
                                         throws InvalidPortletModeException

Returns the current portlet mode. If there is no portlet mode information in the state holder, the portlet mode 'View' will be returned.

Returns:

The current PortletMode or the default portlet mode 'View'. Does not return null.

Throws:

InvalidPortletModeException - - if the portlet mode found in the state holder is invalid (e.g. if it cannot be converted to PortletMode).

getPortletMode

javax.portlet.PortletMode getPortletMode(javax.portlet.PortletMode defaultMode)
                                         throws InvalidPortletModeException

Returns the current portlet mode. If there is no portlet mode information in the state holder, the default mode is returned

Parameters:

defaultMode - the mode returned if no portlet-state is set explicitly in the state object

Returns:

The current PortletMode or the default portlet mode. Does not return null.

Throws:

InvalidPortletModeException - - if the portlet mode found in the state holder is invalid (e.g. if it cannot be converted to PortletMode).

Since:

6.1.0.1

getWindowState

javax.portlet.WindowState getWindowState()
                                         throws InvalidWindowStateException

Returns the current window state. If there is no window state information in the state holder, the window state 'Normal' will be returned.

Returns:

The current WindowState or the default window state 'Normal'. Does not return null).

Throws:

InvalidWindowStateException - - if the window state found in the state holder is invalid (e.g. if it cannot be converted to WindowState).

getWindowState

javax.portlet.WindowState getWindowState(javax.portlet.WindowState defaultState)
                                         throws InvalidWindowStateException

Returns the current window state. If there is no window state information in the state holder, the default state is returned

Parameters:

defaultState - the state returned if no window-state is set explicitly in the state object

Returns:

The current WindowState or the default window. Does not return null).

Throws:

InvalidWindowStateException - - if the window state found in the state holder is invalid (e.g. if it cannot be converted to WindowState).

Since:

6.1.0.1
