Interface FileResource

All Known Implementing Classes:
FSFileResource

public interface FileResource
This is a basic interface to handle a logical "file". This should enable code-agnostic handling of files from different sources: file system, database, etc.
  • Field Details

    • FILE_EXTENSION

      static final Property FILE_EXTENSION
  • Method Details

    • getResourceId

      String getResourceId()
      This is only used in logging to identify which file may have caused problems. While it is probably best to use unique ids for the sake of debugging, it is not necessary that the ids be unique. This id is never used as a hashkey by the batch processors, for example.
      Returns:
      an id for a FileResource
    • getMetadata

      Metadata getMetadata()
      This gets the metadata available before the parsing of the file. This will typically be "external" metadata: file name, file size, file location, data stream, etc. That is, things that are known about the file from outside information, not file-internal metadata.
      Returns:
      Metadata
    • openInputStream

      InputStream openInputStream() throws IOException
      Returns:
      an InputStream for the FileResource
      Throws:
      IOException
