Method Detail

clone

public static IBaseDataObject clone(IBaseDataObject iBaseDataObject)

Clones an IBaseDataObject.

Parameters:

iBaseDataObject - the IBaseDataObject to be cloned.

Returns:

the clone of the IBaseDataObject passed in.

clone

@Deprecated
public static IBaseDataObject clone(IBaseDataObject iBaseDataObject,
                                    boolean fullClone)

Deprecated.

prefer clone(IBaseDataObject)

Clones an IBaseDataObject equivalently to emissary.core.BaseDataObject.clone(), which duplicates some attributes. A "fullClone" duplicates all attributes.

Parameters:

iBaseDataObject - the IBaseDataObject to be cloned.

fullClone - specifies if all fields should be cloned.

Returns:

the clone of the IBaseDataObject passed in.
