Method Detail

clone

public IAnswerData clone()

Specified by:

clone in interface IAnswerData

Overrides:

clone in class Object

getDisplayText

public String getDisplayText()

Specified by:

getDisplayText in interface IAnswerData

Returns:

Gets a string representation of this answer

getValue

public Object getValue()

Specified by:

getValue in interface IAnswerData

Returns:

The value of this answer, will never be null

setValue

public void setValue(Object o)

Specified by:

setValue in interface IAnswerData

Parameters:

o - the value of this answerdata object. Cannot be null. Null Data will not overwrite existing values.

readExternal

public void readExternal(DataInputStream in,
                         PrototypeFactory pf)

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

uncast

public UncastData uncast()

Description copied from interface: IAnswerData

Data types can be uncast if they are expected to be used in different contexts. This allows, for instance, select values to be generated by casting other types or vic-a-versa.

Specified by:

uncast in interface IAnswerData

Returns:

An uncast representation of this answer which can be used in a different context.

cast

public IntegerData cast(UncastData data)
                 throws IllegalArgumentException

Description copied from interface: IAnswerData

Casts the provided data into this data type.

Specified by:

cast in interface IAnswerData

Parameters:

data - An uncast data value which is compatible with this data type

Returns:

An instance of the instance's data type which contains that value

Throws:

IllegalArgumentException - If the uncast data is not in a compatible format

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
