DropboxConnector

Accesses the Dropbox file storage service to upload, download, or delete files and folders or list the contents of a folder from a Dropbox account.

Typical Uses

  • Manage datasets on Dropbox by uploading, downloading, and deleting files and folders
  • Transfer a file's contents (such as XML or raster) into or out of an attribute in FME
  • Read downloaded Dropbox data using the FeatureReader, or upload data written by the FeatureWriter to Dropbox
  • Retrieve file and folder names, paths, links and other information from Dropbox to use elsewhere in a workspace.

How does it work?

The DropboxConnector uses your Dropbox account credentials (either via a previously defined FME web connection, or by setting up new FME web connection right from the transformer) to access the file storage service.

Depending on your choice of actions, it will upload or download files, folders, and attributes; list information from the service; or delete items from the service. On uploads, link attributes are added to the output features. On List actions, file/folder information is added as attributes.

Usage Notes

This transformer cannot be used to directly move or copy files between different Dropbox locations. However, multiple DropboxConnectors can be used to accomplish these tasks.

The performance of this transformer is dependent on the amount of memory allocated to the Java Virtual Machine (JVM). The following environment variables allow you to specify memory available to Java Plugins:

  • FME_JVM_MIN_HEAP_SIZE: Initial heap size for initializing the JVM. Default value is 1024K.
  • FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing JVM. Default value is 16384K.

If unset, the JVM applies the default values. If set, the values must be multiples of 1024K (for example, 4M and 64M, or 4096K and 32768K).

Note: To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.

Parameters

The remaining parameters available depend on the value of the Request > Dropbox Action parameter. Parameters for each Dropbox Action are detailed below.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
