toBoolean

public static boolean toBoolean(Boolean value)

Converts the given Boolean to a primitive boolean value

   BooleanExtensions.toBoolean(Boolean.TRUE)  = true
   BooleanExtensions.toBoolean(Boolean.FALSE) = false
   BooleanExtensions.toBoolean(null)          = false
 

Parameters:

value - the boolean value to convert

Returns:

true if the given Boolean encapsulates the value 'true' otherwise false, that includes even if the given Boolean is null
