"loop repository can not read"

blatoo

Hi all,

I am confused about the operator "loop repository".

I have a bundle of data set with the same format, I want use the "loop repository" to deal with all the data sets.

I made a small example: I want to "retrieve" all the data set in my folder. How can I do that?

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="6.1.000">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="6.1.000" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="loop_repository" compatibility="6.1.000" expanded="true" height="76" name="Loop Repository" width="90" x="246" y="255">
        <parameter key="repository_folder" value="../data/sepData/"/>
        <process expanded="true">
          <operator activated="true" class="retrieve" compatibility="6.1.000" expanded="true" height="60" name="Retrieve" width="90" x="313" y="255">
            <parameter key="repository_entry" value="%{repository_path}%{entry_name}"/>
          </operator>
          <connect from_op="Retrieve" from_port="output" to_port="out 1"/>
          <portSpacing port="source_repository object" spacing="0"/>
          <portSpacing port="source_in 1" spacing="0"/>
          <portSpacing port="sink_out 1" spacing="0"/>
          <portSpacing port="sink_out 2" spacing="0"/>
        </process>
      </operator>
      <connect from_op="Loop Repository" from_port="out 1" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

Thanks!

Hi,

you almost had it
However the %{repository_path} contains the full path including the name of the ioobject already. So just remove %{entry_name} from the Retrieve operator parameter, and you're done. Otherwise you end up trying to find //Local Repository/folder/myDatamyData instead of //Local Repository/folder/myData

Regards,
Marco
