Method Details
-
getType
int getType()Parameter buffer type (this usually is the version of the parameter buffer).- Returns:
- Buffer type (for example
ISCConstants.isc_spb_version3
).
-
addPreamble
Allows the metadata to add a preamble to the parameter buffer.This is only intended for the weird "version 2" connection service parameter buffer that requires two tags for the version with
isc_spb_version, isc_spb_current_version
.- Parameters:
parameterBuffer
- Parameter buffer.
-
getStringArgumentType
