Direct Known Subclasses:

InputOutputExtentField

public abstract class InputOutputExtentParameter<T extends BaseDataType>
extends AbstractExtentParameter<T>

Special wrapper used for variables passed as input-output extent parameters to functions or procedures. On normal function and procedure exit, if the reference for an output or input-output extent parameter has changed, this will update the caller's variable reference too.

Constructor Detail

InputOutputExtentParameter

public InputOutputExtentParameter()

The constructor responsible for instance initialization by calling AbstractExtentParameter(BaseDataType[]).

InputOutputExtentParameter

protected InputOutputExtentParameter(T[] variable)

This constructor allows to provide additional initialization logic of the variable reference in the extending classes. The initialization logic is encapsulated in AbstractExtentParameter(BaseDataType[]).

Parameters:

variable - A valid and initialized variable reference.

Method Detail

initParameter

public T[] initParameter()

Initializes the indeterminate or determinate extent parameter reference depending on the extent (array size) of the value returned by AbstractExtentParameter.getVariable(). A zero value will initialize an indeterminate extent, a positive integer will initialize a determinate extent. The extent will be registered with ArrayAssigner accordingly.

Specified by:

initParameter in class AbstractExtentParameter<T extends BaseDataType>

Returns:

The initialized indeterminate extent parameter reference.

initParameter

public T[] initParameter(int extent)

Initializes the indeterminate or determinate extent parameter reference depending on the extent value. A zero value will initialize an indeterminate extent, a positive integer will initialize a determinate extent. The extent will be registered with ArrayAssigner accordingly.

Specified by:

initParameter in class AbstractExtentParameter<T extends BaseDataType>

Parameters:

extent - The parameter extent size.

Returns:

The initialized indeterminate extent parameter reference.
