Method Detail

getValueOfExpression

public static <T> T getValueOfExpression(String expression,
                         Class<T> targetType)

getValueOfExpressionAsString

public static String getValueOfExpressionAsString(String expression)

getViewConfigPageParameters

public static Set<RequestParameter> getViewConfigPageParameters()

addPageParameters

public static String addPageParameters(javax.faces.context.ExternalContext externalContext,
                       String url,
                       boolean encodeValues)

Adds the current request-parameters to the given url

Parameters:

externalContext - current external-context

url - current url

encodeValues - flag which indicates if parameter values should be encoded or not

Returns:

url with request-parameters

encodeURLParameterValue

public static String encodeURLParameterValue(String value,
                             javax.faces.context.ExternalContext externalContext)

Encodes the given value using URLEncoder.encode() with the charset returned from ExternalContext.getResponseCharacterEncoding(). This is exactly how the ExternalContext impl encodes URL parameter values.

Parameters:

value - value which should be encoded

externalContext - current external-context

Returns:

encoded value
