2.1. Working with the data hierarchy

Opening a file with this FileHandler will display a three pane window as shown below:

The upper pane contains a hierarchical representation of the decoded data in its “Data” tab and a trace of the decoding process in the “Trace” tab. Both tabs provide the same information while the former is more user friendly and the latter is better suited for text based comparison for example.

The lower left pane contains a HEX dump with the associated ASCII representation of the full loaded data. Selecting an item in the top pane will highlight the correponding octets (bytes) in the left part of this pane. The highlighted section includes the full item, e.g. its tag and all its data.

The lower right pane contains a textual representation of the item selected in the hierarchy tree in the top pane. It is empty if no item is currently selected. In case of a decoding error, this displays the full error message of the first encountered error (often there are following errors after the first one) and will never display anything else.
