All Known Implementing Classes:

public interface BrowseDAOUtils

Utility class for retrieving the size of the columns to be used in the browse tables, and applying truncation to the strings that will be inserted into the tables. Can be configured in dspace.cfg, with the following entries: webui.browse.value_columns.max - the maximum number of characters in 'value' columns (0 is unlimited) webui.browse.sort_columns.max - the maximum number of characters in 'sort' columns (0 is unlimited) webui.browse.value_columns.omission_mark - a string to append to truncated values that will be entered into the value columns (ie. '...') By default, the column sizes are '0' (unlimited), and no truncation is applied, EXCEPT for Oracle, where we have to truncate the columns for it to work! (in which case, both value and sort columns are by default limited to 2000 characters).
