This component is used to retrieve a list of entries in a directory, the entries are retrieved one at a time until there are no more entries to retrieve.
The directory is specified by the parameter Directory and is overridden to the data input [In]dir when the input event [In]set dir is asserted. If a valid directory has been specified then the output event [Out]Ready is triggered, else [Out]Error is triggered. The directory path is relative to "userdata" in the EHS root directory unless the "use app dir" option is true, in which case the files are relative to "appdata" which are are packaged in the RESOURCE section of iAB's project.
If it is required, the root directory of the device can be referenced by prefixing the path with the "/" character if OS specific file system data is needed (This should be avoided!).

A list of entries in the directory is presented, one entry at a time, to the data output [Out]name on each occassion that the input event [In]get entry is asserted and the output event [Out]file or [Out]dir is triggered depending on whether the entry is a file or directory respectively. If there are no further entries in the list then the output event [Out]no more is triggered when the input event [In]get entry is asserted. The parameter FindFiles is a Boolean value that specifies if files should be retrieved from the list of entries. Similarly the parameter FindDirs is a Boolean value that specifies if directories should be retrieved from the list of entries.

The reset input event [In]reset will retrieve the first entry in the list the next time that the input event [In]get entry is asserted. If the input event [In]set dir is triggered then this also resets to retrieve the first entry in the list for the specified directory.
