data -

GeoTraceData

public GeoTraceData(GeoTraceData.GeoTrace atrace)

Method Details

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

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 GeoTraceData 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

toBoolean

public Boolean toBoolean()

Specified by:

toBoolean in interface IExprDataType

toNumeric

public Double toNumeric()

Specified by:

toNumeric in interface IExprDataType

toString

public String toString()

Specified by:

toString in interface IExprDataType

Overrides:

toString in class Object
