Method Detail

get

public static IntType get()

instance

public static IntType instance()

parse

public Integer parse(String sourceValue)
              throws ParsingException

Description copied from interface: ValueType

Attempts to parse the passed String into the destinationType. All trimming (removing whitespace from around a value) should be assumed to already have happened for the incoming sourceValue by a Trimmer. Implementations should be careful to ONLY throw a ParsingException - Integers and other types may throw other unchecked exceptions when trying to convert values, which should be handled in this method and rethrown as a ParsingException. This method and toString(T) should be reversible: The object generated here should be toString-able to a String equal to the one passed this method.

Returns:

null if null, or a value of type T

Throws:

ParsingException - for any type of failure.

cast

public Integer cast(Object o)
             throws RuntimeException

Description copied from interface: ValueType

Attempt to cast the passed object to the generic type T. AndHow uses this internally to cast values known to already be of type T, but were stored in a generic way. If used for unknown types that are not castable to T, it will throw a RuntimeException.

Returns:

Throws:

RuntimeException
