Relationships
| Name | Description |
|---|---|
| comms.failure | If the processor is unable to communicate with one of the necessary services, the input FlowFile will be routed to this relationship. |
| failure | If a FlowFile cannot be convert into a CSV, the input FlowFile will be routed to this relationship. |
| success | When the table text has been successfully extracted, the CSV representation of the text will be routed to this relationship. |
| table.not.found | If the processor determines that an input FlowFile does not contain a table, the original FlowFile will be routed to this relationship. |
Reads Attributes
| Name | Description |
|---|---|
| table.text.json | If present, the processor will use this JSON to extract the table text instead of performing OCR. The format expected is an array of JSON objects, each containing a 'text' field as well as an 'x', 'y', 'width', and 'height' field, all of which are floating-point numbers. |
Writes Attributes
| Name | Description |
|---|---|
| filename | The filename of the FlowFile. |
| mime.type | The MIME type of the FlowFile. |
| table.text.json | If the processor successfully extracts the table text, or if it is determined that the FlowFile does not contain a table, this attribute will be removed. |
