The window element
This option specifies the window size to use when performing incremental loads.
<window
Properties:
desc="cdata"
>
...pcdata...
</window>
The window element is used within the following other elements:
data
The window size is in records. There are two separate settings. The first setting is the number of records
before the current record that are retained in memory. These are records earlier than the current record in
document order and have already been processed. The second setting is the number of records after the
current record that are pre-loaded into memory. These are records that are later than the current record in
document order and have not yet been processed.
Content
The content must be either a single non-negative integer or a pair of non-negative integers separated by a
comma. If only one number is supplied then it is used for both settings. If two numbers are supplied the
first one controls the before window and the second one controls the after window. For example, a value
of 1 causes the XFA processor to hold the previous record, the current record, and the next record in
memory. By contrast a value of 0,1 causes the XFA processor to hold only the current record and the next
record in memory.
The desc property
An attribute to hold human-readable metadata.
