6 | * A TemplateField is a specification for either a 'domain field' of a subclass of TemplateEntity or a |
---|
7 | * 'template field' for a specific Template. See the Template class for an explanation of these terms. |
---|
8 | * The TemplateField class contains all information which is needed to specify what kind of data can be stored |
---|
9 | * in this particular field, such as the TemplateFieldType, the name, the ontologies from which terms can derive |
---|
10 | * in case of an ONTOLOGYTERM field, the list entries in case of a STRINGLIST fields, and so on. |
---|
11 | * The actual values of the template fields are stored in instances of subclasses of the TemplateEntity class. |
---|
12 | * For example, if there exists a Study template with a 'description' TemplateField as a member of Template.fields, |
---|
13 | * the actual description for each Study would be stored in the inherited templateStringFields map of that Study instance. |
---|
14 | * |
---|
15 | * One TemplateField can belong to many Templates, but they have to be the same entity as the TemplateField itself. |
