Method Details

getActionURL

public URL getActionURL(FacesContext context)
                 throws MalformedURLException

Construct an absolute URL to this NavigationCase instance using ViewHandler.getActionURL(jakarta.faces.context.FacesContext, java.lang.String) on the path portion of the url.

Parameters:

context - the FacesContext for the current request

Returns:

the action URL.

Throws:

MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getResourceURL

public URL getResourceURL(FacesContext context)
                   throws MalformedURLException

Construct an absolute URL to this NavigationCase instance using ViewHandler.getResourceURL(jakarta.faces.context.FacesContext, java.lang.String) on the path portion of the url.

Parameters:

context - the FacesContext for the current request

Returns:

the resource URL.

Throws:

MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getRedirectURL

public URL getRedirectURL(FacesContext context)
                   throws MalformedURLException

Construct an absolute URL suitable for a "redirect" to this NavigationCase instance using ViewHandler.getRedirectURL(jakarta.faces.context.FacesContext, java.lang.String, java.util.Map<java.lang.String, java.util.List<java.lang.String>>, boolean) on the path portion of the url.

Parameters:

context - the FacesContext for the current request

Returns:

the redirect URL.

Throws:

MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getBookmarkableURL

public URL getBookmarkableURL(FacesContext context)
                       throws MalformedURLException

Construct an absolute URL suitable for a bookmarkable link to this NavigationCase instance using ViewHandler.getBookmarkableURL(jakarta.faces.context.FacesContext, java.lang.String, java.util.Map<java.lang.String, java.util.List<java.lang.String>>, boolean) on the path portion of the url. This URL may include view parameters specified as metadata within the view.

Parameters:

context - the FacesContext for the current request

Returns:

the bookmarkable URL.

Throws:

MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getFromViewId

public String getFromViewId()

Return the <from-view-id> of the <navigation-rule> inside which this <navigation-case> is nested.

Returns:

the from viedId.

getFromAction

public String getFromAction()

Return the <from-action> for this <navigation-case>

Returns:

the from action.

getFromOutcome

public String getFromOutcome()

Return the <from-outcome> for this <navigation-case>

getToViewId

public String getToViewId(FacesContext context)

Evaluates the <to-view-id> for this <navigation-case>

Parameters:

context - the FacesContext for the current request

Returns:

the view ID that should be navigated to

getToFlowDocumentId

public String getToFlowDocumentId()

If this navigation case represents a flow invocation, this property is the documentId in which the flow whose id is given by the return from getFromOutcome() is defined. Implementations must override this method to return the value defined in the corresponding application configuration resources element. The base implementation returns the empty string.

Returns:

the toFlow documentId.

Since:

2.2

hasCondition

public boolean hasCondition()

Test if this navigation case has an associated <if> element.

Returns:

true if there's an <if> element associated with this <navigation-case>, otherwise false

getCondition

public Boolean getCondition(FacesContext context)

Evaluates the <if> for this <navigation-case>, if any. The expression to be evaluated is passed into the constructor as a string. When the expression is evaluated, its value must be coerced into a boolean per the normal Jakarta Expression Language coercion rules.

Note throws any exceptions encountered during the process of evaluating the expression or obtaining its value.

Parameters:

context - the FacesContext for the current request

Returns:

null if there is no <if> element associated with this <navigation-case>, otherwise return the evaluation result of the condition

getParameters

public Map<String,List<String>> getParameters()

Returns:

true if this is a redirect, false otherwise.

isIncludeViewParams

public boolean isIncludeViewParams()

Return the <redirect> value for this <navigation-case>. This will be true if the view parametets should be encoded into the redirect URL (only applies to redirect case)

Returns:

true if view parameters are to be included, false otherwise.
