toString

public static String toString(FacesContext context,
 UIComponent component,
 Object value)
                       throws ConverterException

Converts specified component value to a string, using component's converter. Nulls are converted to empty strings ("").

Parameters:

context - Current context.

value - Value to convert.

Returns:

String representation of value.

Throws:

ConverterException

isEmpty

public static boolean isEmpty(String s)

 int defaultValue)

Converts o to an int. If o is null or not convertable, returns defaultValue.

doubleValue

public static double doubleValue(Object o,
 double defaultValue)

Converts o to a double. If o is null or not convertable, returns defaultValue.

isPrimitiveType

public static boolean isPrimitiveType(String type)

True if type name is a primitive type (ie "boolean").

getPrimitiveType

public static Class<?> getPrimitiveType(String type)

Gets class for primitive type name (ie Boolean for "boolean").

getLocalFromToString

public static Locale getLocalFromToString(String sLocale)

Convert an Locale.toString() text to a Locale Object.

Parameters:

sLocale - from a Locale.toString() output.
