Class URITableLocationKey
java.lang.Object
io.deephaven.engine.table.impl.locations.impl.PartitionedTableLocationKey
io.deephaven.engine.table.impl.locations.local.URITableLocationKey
- All Implemented Interfaces:
LogOutputAppendable
,ImmutableTableLocationKey
,TableLocationKey
,NamedImplementation
,Comparable<TableLocationKey>
- Direct Known Subclasses:
ParquetTableLocationKey
Base
ImmutableTableLocationKey
implementation for table locations that may be enclosed by partitions and
described by a URI
. Sub-classes should override compareTo(TableLocationKey)
and
equals(Object)
only if they need to prevent equality with other URITableLocationKey
implementations.-

URITableLocationKey
public URITableLocationKey(@NotNull @NotNull URI uri, int order, @Nullable @Nullable Map<String, Comparable<?>> partitions) Construct a new URITableLocationKey for the supplieduri
andpartitions
.- Parameters:
uri
- The uri (or directory) that backs the keyed location. Will be adjusted to an absolute path.order
- Explicit ordering value for this location key.Comparable.compareTo(Object)
will sort URITableLocationKeys with a lowerorder
before other keys. Comparing this ordering value takes precedence over other fields.partitions
- The table partitions enclosing the table location keyed bythis
. Note that if this parameter isnull
, the location will be a member of no partitions. An ordered copy of the map will be made, so the calling code is free to mutate the map after this call completes, but the partition keys and values themselves must be effectively immutable.

getImplementationName
Description copied from interface:NamedImplementation
Get a name for the implementing class. Useful for abstract classes that implement
LogOutputAppendable
or overridetoString
.The default implementation is correct, but not suitable for high-frequency usage.
- Returns:
- A name for the implementing class
-
