function entity_form_submit_build_entity

Copies submitted values to entity properties for simple entity forms.

During the submission handling of an entity form's "Save", "Preview", and possibly other buttons, the form state's entity needs to be updated with the submitted form values. Each entity form implements its own builder function for doing this, appropriate for the particular entity and form, whereas modules may specify additional builder functions in $form['#entity_builders'] for copying the form values of added form elements to entity properties. Many of the main entity builder functions can call this helper function to re-use its logic of copying $form_state['values'][PROPERTY] values to $entity->PROPERTY for all entries in $form_state['values'] that are not field data, and calling field_attach_submit() to copy field data. Apart from that this helper invokes any additional builder functions that have been specified in $form['#entity_builders'].

For some entity forms (e.g., forms with complex non-field data and forms that simultaneously edit multiple entities), this behavior may be inappropriate, so the builder function for such forms needs to implement the required functionality instead of calling this function.
