Method Detail

getDestinationType

public Class<T> getDestinationType()

Specified by:

getDestinationType in interface ValueType<T>

isParsable

public boolean isParsable(String sourceValue)

Description copied from interface: ValueType

Returns true if the string can safely be parsed into the destination type by the parse() method.

Specified by:

isParsable in interface ValueType<T>

Returns:

true or false - this should never throw an exception.

toString

public String toString(T value)

Description copied from interface: ValueType

Converts an instance of the destination type to string. For most types, simply calling T.toString() is a good enough implementation. For dates, times and other more complex types, more detailed conversion may be needed. This method and parse() should be reversible: The string generated here should be parsable to an object equal to the one passed this methond.

Specified by:

toString in interface ValueType<T>

Returns:

null if the passed value is null.
