Constructor Detail

ExtendedTableInfo

public ExtendedTableInfo(java.lang.String[] items,
                         java.lang.String mode,
                         java.lang.String[] fields,
                         boolean snapshot)
                  throws SubscrException

Constructs a table specification with basic table attributes.

Parameters:

items - Array of names of the items in the table.

mode - Subscription mode for all items in the table.

fields - Array of names of the fields for all items in the table.

snapshot - If true, requires the snapshot for all items in the table. The snapshot can be requested only for MERGE, DISTINCT and COMMAND Items mode. However, the flag is ignored if requestUnfilteredDispatching() is also called, as snapshot management is currently not supported for unfiltered COMMAND mode.

Throws:

SubscrException - Thrown if the snapshot request is not compatible with the supplied subscription mode.

Method Detail

setRange

public void setRange(int start,
                     int end)

Inherited from SimpleTableInfo, but ignored in this case. Specifying a subrange of the specified Group of items to be requested is only meaningful when Group names must be used, so that an explicit specification for the needed subrange as a Group may not be available.

Overrides:

setRange in class SimpleTableInfo

Parameters:

start - ignored.

end - ignored.
