Method Detail

getValueForExpression

public java.lang.Object getValueForExpression(javax.faces.context.FacesContext ctx,
                                              java.lang.String expression)

Description copied from interface: JsfFacade

For given expression, lookups ValueBinding / ValueExpression and retrieves the value from it. If no binding / expression is found (null), so no value can be retrieved from it, a JavalidException is raised. Note that null can be returned, but that would mean we found a ValueBinding / ValueExpression except the value from it was null. If an exception occurs for any other reason a JavalidException is raised.

Specified by:

getValueForExpression in interface JsfFacade

Parameters:

ctx - The current facescontext

expression - The expression to resolve

Returns:

Object from ValueBinding / ValueExpression

setValueForExpression

public void setValueForExpression(javax.faces.context.FacesContext ctx,
                                  java.lang.String expression,
                                  java.lang.Object newValue)

Description copied from interface: JsfFacade

For given expression, lookups ValueBinding / ValueExpression and sets the newValue on it. If no binding/expression is found (null), thus no value can be set on it, a JavalidException is raised. If an exception occurs for any other reason a JavalidException is raised.

Specified by:

setValueForExpression in interface JsfFacade

Parameters:

ctx - The current facescontext

expression - The expression to resolve

newValue - The new value to set on the valuebinding / valueexpression.

getValueForComponentProperty

public java.lang.Object getValueForComponentProperty(javax.faces.context.FacesContext ctx,
                                                     javax.faces.component.UIComponent component,
                                                     java.lang.String propertyName)

Description copied from interface: JsfFacade

Gets the value of a property from a component. For instance on a JSF input component, you can retrieve the value by setting the property to 'value'. Raises JavalidException if an error occurs.

Specified by:

getValueForComponentProperty in interface JsfFacade

Parameters:

ctx - The context

component - The actual component to get it from

propertyName - The property name

Returns:

The actual value

setValueForComponentProperty

public void setValueForComponentProperty(javax.faces.context.FacesContext ctx,
                                         javax.faces.component.UIComponent component,
                                         java.lang.String propertyName,
                                         java.lang.Object newValue)

Description copied from interface: JsfFacade

Sets a new value for given property from a component. For instance on a JSF input component, you can set the value by setting the property to 'value' and give the newValue for it.

Specified by:

setValueForComponentProperty in interface JsfFacade

Parameters:

ctx - The context

component - The actual component to get the property and set the value on

propertyName - Property name

newValue - The new value

setValueForComponentPropertyWithExpression

public void setValueForComponentPropertyWithExpression(javax.faces.context.FacesContext ctx,
                                                       javax.faces.component.UIComponent component,
                                                       java.lang.String propertyName,
                                                       java.lang.String expressionValue)

Description copied from interface: JsfFacade

Sets a new value for given property from a component. For instance on a JSF input component, you can set the value by setting the property to 'value' and give an expression for it, which will be resolved.

Specified by:

setValueForComponentPropertyWithExpression in interface JsfFacade

Parameters:

ctx - The context

component - The actual component to get the property and set the value on

propertyName - Property name

expressionValue - The expression value

getExpressionStringForComponentProperty

public java.lang.String getExpressionStringForComponentProperty(javax.faces.component.UIComponent component,
                                                                java.lang.String propertyName)

Description copied from interface: JsfFacade

Returns the expression string from either the ValueBinding/ValueExpression that is resolved from the component using given property. E.g. <h:inputText value=#{bean.name}"" /> would return #{bean.name} if the property value was asked for.

Specified by:

getExpressionStringForComponentProperty in interface JsfFacade

Parameters:

component - The component

propertyName - The property

Returns:

Expression String
