Usage

From source file:org.obiba.magma.beans.BeanVariableValueSourceFactory.java

protected Variable doBuildVariable(Class<?> propertyType, String name) {
    ValueType type = ValueType.Factory.forClass(propertyType);

    Variable.Builder builder = Variable.Builder.newVariable(name, type, entityType);

        String[] names = Iterables.toArray(
                Iterables.transform(Arrays.asList(constants), Functions.toStringFunction()), String.class);
        builder.addCategories(names);// w w w . jav  a2  s .  c  om
    }

    if (occurrenceGroup != null) {
        builder.repeatable().occurrenceGroup(occurrenceGroup);
    }

    builder.accept(variableBuilderVisitors);

    // Allow extended classes to contribute to the builder
