Method Detail
-
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
void addPreamble(ParameterBuffer parameterBuffer)
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
ArgumentType getStringArgumentType(int tag)
Gets the string argument type for the supplied tag.When the tag is not known (or unsupported for string arguments), then the default should be returned.
- Parameters:
tag- Tag (item type)- Returns:
- Argument type (never
null)
-
getByteArrayArgumentType
ArgumentType getByteArrayArgumentType(int tag)
Gets the byte array argument type for the supplied tag.When the tag is not known (or unsupported for string arguments), then the default should be returned.
- Parameters:
tag- Tag (item type)- Returns:
- Argument type (never
null)
-
getIntegerArgumentType
ArgumentType getIntegerArgumentType(int tag)
Gets the byte array argument type for the supplied tag.When the tag is not known (or unsupported for string arguments), then the default should be returned.
- Parameters:
tag- Tag (item type)- Returns:
- Argument type (never
null)
