    • orderBy

      public UiQueryTable<E> orderBy(org.obrel.core.RelationType<?> orderAttribute, boolean ascending)

    • setColumns

      public void setColumns(Collection<de.esoco.lib.expression.Function<? super E,?>> columnAttributes)
      Sets the entity attributes to be displayed as the table columns. The datatype of a column is a function that queries the attributes from an entity. This applies to standard relation types as these are also functions that can be applied to relatable objects (like entities). But that can also be compound functions that generate the attribute value to displayed in a result table on access. An example could be a function that extracts the name from an entity reference (e.g. NAME.from(OTHER_ENTITY)).
      Parameter:
      columnAttributes - The entity attribute access functions

    • setOrderBy

      public void setOrderBy(de.esoco.lib.expression.Predicate<? super Entity> order)
      Sets the default query order with a predicate that may contain multiple order criteria. For ordering by a single entity attribute see method setOrderBy(RelationType, boolean).
      Parameter:
      order - The sort order criteria (NULL for none)

    • setOrderBy

      public void setOrderBy(org.obrel.core.RelationType<?> orderAttribute, boolean ascending)
      Sets the default query order for a single attribute. For complex order criteria see setOrderBy(Predicate).
      Parameter:
      orderAttribute - The entity attribute to order the query by
      ascending - TRUE for ascending, FALSE for descending ordering

    • setQuery

      public void setQuery(de.esoco.lib.expression.Predicate<? super E> criteria)

    • setSelection

      public void setSelection(E value)
      Sets (or clears) the currently selected entity.
