=head1 Link Types
|
|
|
|
Links are an extensible mechanism for adding new kinds of database link,
|
|
using JSON for link addresses.
|
|
The following link types are available in this release:
|
|
|
|
=over
|
|
|
|
=item * L<Constant|/"Constant Link const">
|
|
|
|
=item * L<Database|/"Database Link db">
|
|
|
|
=item * L<Channel Access|/"Channel Access Link ca">
|
|
|
|
=back
|
|
|
|
=head2 Using Links
|
|
|
|
...
|
|
must appear inside a pair of braces C< {} > expressed as a JSON
|
|
(L<JavaScript Object Notation|http://www.json.org/>) object, which allows link
|
|
parameters to be defined as needed.
|
|
|
|
Note that due to the required presence of the double-quote characters in the
|
|
JSON strings in a link field value string in a database file, it will usually
|
|
be necessary to escape all double-quote characters in the JSON object by
|
|
preceding them with a backslash C< \ > character.
|
|
Database configuration tools that support this link mechanism must be careful
|
|
to handle these escapes correctly on reading and writing string values from/to
|
|
a .db file.
