Interface FieldModel

All Superinterfaces:
ModelElement, ModuleTracker
All Known Implementing Classes:
DefaultFieldModel, FieldModelImpl

public interface FieldModel extends ModelElement, ModuleTracker
The model of one Entity Model's field.

The backendData is of type FieldModelInfo.

  • Method Details

    • getName

      String getName()
      Returns the entity field name; the name attribute of the field tag in xml.
    • getTarget

      String getTarget()
      Returns the internal field name, eg db table field name; the target attribute of the field tag in xml.
    • isNullable

      boolean isNullable()
      Tells if the field accepts the null value to be stored in it. Key fields are never nullable.
    • isUnique

      boolean isUnique()
      Tells if the field's values are unique (i.e. a value may only exists once)
      true if the field's values are unique
    • isKey

      boolean isKey()
      Tells if this field is the or part of the primary key.

      It has nothing to do with indexed fields, nor with foreign keys.

    • isVirtual

      boolean isVirtual()
    • isSynthetic

      boolean isSynthetic()
    • getType

      Type<?> getType()
      Returns the nice Type object which for example represents a string.
    • getDefaultValue

      Object getDefaultValue()
      Returns the DefaultValueDescriptor. This is the dynamic default value that can be defined on the entity as well as on the form.

      The reason that this signature returns 'Object' is because the interface cannot be seen.

      instance of DefaultValueDescriptor

    • setLocalized

      void setLocalized(boolean flag)
      flag - true to make it a multilingual field, false to not.
    • isLocalized

      boolean isLocalized()
