Parameters:
fromViewId - return from getFromViewId()
fromAction - return from getFromAction()
fromOutcome - return from getFromOutcome()
condition - A string to be interpreted as a ValueExpression by a call to getCondition(javax.faces.context.FacesContext)
toViewId - return from getToViewId(javax.faces.context.FacesContext)
parameters - return from getParameters()
redirect - return from isRedirect()
includeViewParams - return isIncludeViewParams()

Parameters:
context - the FacesContext for the current request
Throws:
java.net.MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getResourceURL

public java.net.URL getResourceURL(FacesContext context)
                            throws java.net.MalformedURLException

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

Parameters:

Construct an absolute URL suitable for a bookmarkable link to this NavigationCase instance using ViewHandler.getBookmarkableURL(javax.faces.context.FacesContext, java.lang.String, java.util.Map>, 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
Throws:
java.net.MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getFromViewId

public java.lang.String getFromViewId()

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

getFromAction

public java.lang.String getFromAction()

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

getFromOutcome

public java.lang.String getFromOutcome()

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

getToViewId

public java.lang.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

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 java.lang.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 normail EL coercion rules.

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
Throws:
any - exceptions encountered during the process of evaluating the expression or obtaining its value.

getParameters

public java.util.Map<java.lang.String,java.util.List<java.lang.String>> getParameters()

Return the parameters to be included for navigation cases requiring a redirect. If no parameters are defined, null will be returned. The keys in the Map are parameter names. For each key, the corresponding value is a List of unconverted values.

isRedirect

public boolean isRedirect()

Return the <redirect> value for this <navigation-case>. This will be true if the new view should be navigated to via a ExternalContext.redirect(String)

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)

equals

public boolean equals(java.lang.Object o)
Overrides:
equals in class java.lang.Object

hashCode

public int hashCode()
Overrides:
hashCode in class java.lang.Object
