Method Details

getInstance

public static TableLocationKey getInstance()

getImplementationName

public String getImplementationName()

Description copied from interface: NamedImplementation

Get a name for the implementing class. Useful for abstract classes that implement LogOutputAppendable or override toString.

The default implementation is correct, but not suitable for high-frequency usage.

Specified by:

getImplementationName in interface NamedImplementation

Returns:

A name for the implementing class

append

public LogOutput append(LogOutput logOutput)

Specified by:

append in interface LogOutputAppendable

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(@NotNull
 @NotNull TableLocationKey other)

Specified by:

compareTo in interface Comparable<TableLocationKey>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(@Nullable
 @Nullable Object other)

Overrides:

equals in class Object

getPartitionValue

public <PARTITION_VALUE_TYPE extends Comparable<PARTITION_VALUE_TYPE>>
PARTITION_VALUE_TYPE getPartitionValue(@NotNull
 @NotNull String partitionKey)

Description copied from interface: TableLocationKey

Lookup the value of one of the table partitions enclosing the location keyed by this.

Specified by:

getPartitionValue in interface TableLocationKey

Type Parameters:

PARTITION_VALUE_TYPE - The expected type of the partition value

Parameters:

partitionKey - The name of the partition

Returns:

The partition value

getPartitionKeys

public Set<String> getPartitionKeys()

Description copied from interface: TableLocationKey

Get the set of available partition keys.

Specified by:

getPartitionKeys in interface TableLocationKey

Returns:

The set of available partition keys
