Component

The

component
...
supports
...
fixed
...
width
...
and
...
delimited
...
file
...
parsing
...
via

the

Notice:
...
This
...
component
...
only
...
supports

consuming
...
from
...
flatpack
...
files

to

Object
...
model.
...
You
...
can

not

(yet)
...
write
...
from

Object
...
model

to

flatpack
...
format.

Message
...
Headers
...
Camel
...
will
...
store
...
the
...
following
...
headers
...
on
...
the
...
IN
...
message:
| Wiki Markup |
|---|
{div:class=confluenceTableSmall} || Header || Description || | {{camelFlatpackCounter}} | The current row index. For {{splitRows=false}} the counter is the total number of rows. | {div} h3. |
Message
...
Body
...
The
...
component
...
delivers
...
the
...
data
...
in
...
the
...
IN
...
message
...
as
...
a
...
org.apache.camel.component.flatpack.DataSetList
...
object
...
that
...
has
...
converters
...
for
...
java.util.Map
...
or
...
java.util.List
...
.
...
Usually
...
you
...
want
...
the
...
Map
...
if
...
you
...
process
...
one
...
row
...
at
...
a
...
time
...
(
...
splitRows=true
...
).
...
Use
...
List
...
for
...
the
...
entire
...
content
...
(
...
splitRows=false
...
),
...
where
...
each
...
element
...
in
...
the
...
list
...
is
...
a
...
Map
...
.
...
Each
...
Map
...
contains
...
the
...
key
...
for
...
the
...
column
...
name
...
and
...
its
...
corresponding
...
value.
...
For
...
example
...
to
...
get
...
the
...
firstname
...
from
...
the
...
sample
...
below:
| Code Block | ||||
|---|---|---|---|---|
| ||||
{code:java} Map row = exchange.getIn().getBody(Map.class); String firstName = row.get("FIRSTNAME"); {code} |
However,
...
you
...
can
...
also
...
always
...
get
...
it
...
as
...
a
...
List
...
(even
...
for
...
splitRows=true
...
).
...
The
...
same
...
example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
{code:java}
List data = exchange.getIn().getBody(List.class);
Map row = (Map)data.get(0);
String firstName = row.get("FIRSTNAME");
|
Header and Trailer records
The header and trailer notions in Flatpack are supported. However, you must use fixed record IDs:
headerfor the header record (must be lowercase)trailerfor the trailer record (must be lowercase)
The example below illustrates this fact that we have a header and a trailer. You can omit one or both of them if not needed.

{code} h3. Header and Trailer records The header and trailer notions in Flatpack are supported. However, you *must* use fixed record IDs: * {{header}} for the header record (must be lowercase) * {{trailer}} for the trailer record (must be lowercase) The example below illustrates this fact that we have a header and a trailer. You can omit one or both of them if not needed. {code:xml} <RECORD id="header" startPosition="1" endPosition="3" indicator="HBT"> <COLUMN name="INDICATOR" length="3"/> <COLUMN name="DATE" length="8"/> </RECORD> <COLUMN name="FIRSTNAME" length="35" /> <COLUMN name="LASTNAME" length="35" /> <COLUMN name="ADDRESS" length="100" /> <COLUMN name="CITY" length="100" /> <COLUMN name="STATE" length="2" /> <COLUMN name="ZIP" length="5" /> <RECORD id="trailer" startPosition="1" endPosition="3" indicator="FBT"> <COLUMN name="INDICATOR" length="3"/> <COLUMN name="STATUS" length="7"/> </RECORD> {code} h3. Using the endpoint A common use case is sending a file to this endpoint for further processing in a separate route. For example: {code:xml} |
Using the endpoint
A common use case is sending a file to this endpoint for further processing in a separate route. For example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
<route>
<from uri="file://someDirectory"/>
<to uri="flatpack:foo"/>
</route>
<route>
<from uri="flatpack:foo"/>
...
</route>
</camelContext>
{code}
|
You
...
can
...
also
...
convert
...
the
...
payload
...
of
...
each
...
message
...
created
...
to
...
a
...
Map
...
for
...
easy
...
...
