public interface DataElement
The purpose of the Data Element entity is to identify and describe all pieces of information used by the company applications.
A Data Element is a unit of data, considered as 'elementary' during at least one stage in the development of a project.

DataElementBlankWhenZeroValues getBlankWhenZero()
if the Blank when zero COBOL clause is generated, blanks replace the zero values that are normally printed or displayed.
It only applies to numeric Data Elements, for the retrieval of old versions.
java.util.List<DataElement> getChildrenDataElements()
Returns the list of children data elements.
java.util.List<DataElementDescription> getDLines()
The DLines of an data element correspond to the Data Element Description.
It is used to assign explanatory text to the Data Element, and values or ranges of possible values with their meaning.
It is also used to complement the description
java.util.List<GLine> getGELines()
GELines specify the automatically generated error messages, declare explicit error messages, or specify help on a Data Element or an error message.
Library getGenerationLibrary()
Indicates the Library on which we can find the generation parameters for the entity.
Parameters are related to the adaptation to the operating system in use.
java.lang.String getInputFormat()
The input format is specific to the Batch Applications function. It is required when the Data Element is called in a transaction file, used as input in a batch flow.
java.lang.String getInternalFormat()
The internal format is required, except if the Data Element is a Property.
The internal format is used when the Data Element is called in:
An application file (permanent file, database, temporary file),
A Screen as a data-entry field, if no conversational format has been specified .
DataElementInternalUsageValues getInternalUsage()
The internal usage corresponds to the COBOL USAGE clause.
With the USAGE clause of a COBOL numeric variable, you indicate the internal representation of its value. Different usages are available depending on the COBOL variants adapted to the material in use.
java.lang.String getOutputFormat()
The output format is used when the Data Element describes:
A field in a Report
A protected field in a Screen, if no conversational format has been specified
DataElement getParent()
Indicates the parent of the data element.
Data Element is an elementary concept. In your applications, you might want to use several technical variants of this concept. So to guarantee the coherence of your data, you manage these variants by creating parent and child Data Elements.
The characteristics of the parent Data Element (its formats and its usage) are passed on to its child but can modify the characteristics inherited from its parent.
DataElementTypeValues getType()
Indicates the type of the data element : R for a real data element, L for a large object, P for a property, A for an Alias data element and U for an Unicode data element.
