Transformer implementation that can be used to to find parent items |
7772 |
17 Feb 20 |
nicklas |
to children that have a subtype with the "push annotations to parent" |
7772 |
17 Feb 20 |
nicklas |
flag set. |
7772 |
17 Feb 20 |
nicklas |
34 |
|
7772 |
17 Feb 20 |
nicklas |
Example: The source list is extracts of a subtype with this flag. |
7772 |
17 Feb 20 |
nicklas |
This transformer will find all parent items to source list. If |
7772 |
17 Feb 20 |
nicklas |
any of the parent items also has a subtype with the "push annotations" flag |
7772 |
17 Feb 20 |
nicklas |
to process is repeated. |

This implemntatation works with SAMPLE or EXTRACT types only. If starting with a |
7772 |
17 Feb 20 |
nicklas |
SAMPLE list it will also move up to BIOSOURCE and then back down one step. |
7772 |
17 Feb 20 |
nicklas |
If starting with a EXTRACT list it will move up to SAMPLE and BIOSOURCE (if |
7772 |
17 Feb 20 |
nicklas |
all intermediate steps have the "push annotations" flag). |

If used in a chain, this transformation should be used first in the chain. |
