Method Detail

initialize

protected void initialize(java.util.ArrayList fieldNames)

Description copied from class: DataRecordSource

Subclasses must implement this to set themselves up and populate the fieldNames list. The list is empty to start with.

Specified by:

initialize in class DataRecordSource

nextRecord

protected boolean nextRecord(java.util.ArrayList fillThis)

Description copied from class: DataRecordSource

Subclasses must implement this to set the current values in the given arraylist. While this does require pulling all values from e.g. a ResultSet, it prevents oddities such as the can-only-fetch-once bug in MSAccess. The list will already be populated with values, so set(index, value) will work for all indices (assuming your record is the same size as the fieldNames list, of course). It is not nulled out, so be sure to set all values. This is done as a prefetch; return true if the prefetch succeeds.

Specified by:

nextRecord in class DataRecordSource

close

public void close()

Description copied from class: DataRecordSource

Do any cleanup needed. Be sure to call super.close().

Overrides:
