Detailed Description

ERXValueUtilities has useful conversion methods for reading and transforming boolean, int and floatvalues. Unless otherwise stated, when an empty string (or one containing only whitespace) is given, then the string is assumed to be null. This is because D2W is not able to give back null values anymore.

NSArray  def 
) [static]

Basic utility method for reading NSArray values which also works with serialized NSArrays and comma separated items. The default value is used if the object is null.

Deprecated:
use ERXComponentUtilities.booleanValueForBinding(component, binding, def)

static Boolean BooleanValueWithDefault ( Object  obj,

Parameters:
obj object to be evaluated
def default value if object is null
