com.goldencode.p2j.util.OutputExtentField<T>

public class OutputExtentField<T extends BaseDataType>
extends OutputExtentParameter<T>

Data wrapper which associates with a DMO extent property. An instance of this class is used to wrap the extent field when passed to an output parameter. It manages the hidden assignment of an output parameter to the database field with which it is associated, upon return from a procedure or function.

The field reference instance for.

Constructor Detail

OutputExtentField

public OutputExtentField(DataModelObject dmo,
                         java.lang.String property)

Constructor.

Parameters:

dmo - Proxy for record whose field is being accessed.

property - Name of dmo field.

OutputExtentField

public OutputExtentField(DataModelObject dmo,
                         java.lang.String property,
                         boolean initialize)

Constructor.

Parameters:

dmo - Proxy for record whose field is being accessed.

property - Name of dmo field.

initialize - Should this variable be initialized with the DMO's current value for the target field?

OutputExtentField

private OutputExtentField(FieldReference fieldRef)

Constructor used internally to help initialize the instance - FieldReference instance needs to be passed to the parent as well as stored in fieldRef.

Parameters:

fieldRef - A valid FieldReference instance.

Method Detail

getVariable

public T[] getVariable()

Get the current extent reference.

Specified by:

getVariable in class AbstractExtentParameter<T extends BaseDataType>

Returns:

See above.

setVariable

public void setVariable(T[] reference)

Change the caller's reference to the new reference.

Specified by:

setVariable in class AbstractExtentParameter<T extends BaseDataType>

Parameters:

reference - The new reference.

isTableField

protected boolean isTableField()

Check if this parameter is associated with a table field, so a batch assign is required on output parameter processing.

Overrides:

isTableField in class AbstractParameter

Returns:

Always true.

performAssignment

protected void performAssignment()

Perform the assignment from the callee's argument value to the actual field.

Overrides:

performAssignment in class AbstractExtentParameter<T extends BaseDataType>
