Method Summary

Modifier and Type	Method	Description
void	addPreamble(ParameterBuffer parameterBuffer)	Allows the metadata to add a preamble to the parameter buffer.
ArgumentType	getByteArrayArgumentType(int tag)	Gets the byte array argument type for the supplied tag.
ArgumentType	getIntegerArgumentType(int tag)	Gets the byte array argument type for the supplied tag.

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)
