Method Detail

setValueInExpressionString

public static void setValueInExpressionString(FacesContext context,
                                              java.lang.String expressionString,
                                              java.lang.Object value)

getValueForExpressionString

public static java.lang.Object getValueForExpressionString(FacesContext context,
                                                           java.lang.String expressionString,
                                                           boolean withError)
                                                    throws PropertyNotFoundException

Parameters:

withError - If an expression cannot be resolved (e.g. the expression is pointing to a property which does not exist) then you may explicitly decide if "null" is returned (withError set to "false") or if a PropertyNotFound-exception is thrown (withError set to "true").

Throws:

PropertyNotFoundException

getValueForExpressionString

public static java.lang.Object getValueForExpressionString(FacesContext context,
                                                           java.lang.String expressionString)

setFlagSetMayFail

public static void setFlagSetMayFail(java.lang.Object expression,
                                     boolean flagSetMayFail)

By default a set-operation that fails with an expression causes some Error that is thrown. You can explicitly mark an expression so that it knows that set-operations may fail - so no error will be thrown later on.

setValue

public static void setValue(FacesContext context,
                            java.lang.Object expression,
                            java.lang.Object value)

Set value of an expression.

setValue

public static void setValue(FacesContext context,
                            java.lang.Object expression,
                            java.lang.Object value,
                            boolean clearStack)

Internal usage.

getType

public static java.lang.Class getType(FacesContext context,
                                      java.lang.Object expression)

getValue

public static java.lang.Object getValue(FacesContext context,
                                        java.lang.Object expression)

getExpressionString

public static java.lang.String getExpressionString(java.lang.Object expression)

getExpressionFromComponentAttribute

public static java.lang.Object getExpressionFromComponentAttribute(UIComponent component,
                                                                   java.lang.String attributeName)

setExpressionAsComponentAttribute

public static void setExpressionAsComponentAttribute(UIComponent component,
                                                     java.lang.String attributeName,
                                                     java.lang.Object expression)

createExpression

public static java.lang.Object createExpression(Application app,
                                                java.lang.String vbString)

checkIfObjectIsAnExpression

public static boolean checkIfObjectIsAnExpression(java.lang.Object object)

buildTokens

public static java.lang.String[] buildTokens(java.lang.String vbString)

The string vbString is transferred into its tokens.
