  - public boolean asBoolean()
    
    Coerces a double array to a boolean value. A double array is false if the array is of length 0, and true otherwise.
    
    Returns:
    
    the array's boolean value
    
    Since:
    
    1.7.4

    value - the value being searched for
    
    Returns:
    
    true if the array contains the value
    
    Since:
    
    1.8.6
  - public Number count(Object value)
    
    Counts the number of occurrences of the given value inside this array. Comparison is done using Groovy's == operator (using compareTo(value) == 0 or equals(value) ).
    
    Parameters:
    
    value - the value being searched for
    
    Returns:
    
    the number of occurrences
