Method Details

visit

public DeferredTableLocation visit(long stamp)

Description copied from interface: TableLocation

Mark this table location as visited, with the given (time)stamp.

Specified by:

visit in interface TableLocation

Parameters:

stamp - a monotonically increasing value indicating when this location was visited.

Returns:

returns itself for chaining

getVisit

public long getVisit()

Description copied from interface: TableLocation

return the last value set in TableLocation.visit(long)

Specified by:

getVisit in interface TableLocation

Returns:

the last value set in visit()

toString

public final String toString()

Overrides:

toString in class Object

getImplementationName

public final 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

getInternalPartition

@NotNull public final CharSequence getInternalPartition()

Specified by:

getInternalPartition in interface TableLocationKey

Returns:

The internal partition that encloses the identified table location, or null if none exists

getColumnPartition

@NotNull public final CharSequence getColumnPartition()

Specified by:

getColumnPartition in interface TableLocationKey

Returns:

The column partition that encloses the identified table location, or null if none exists

getTableKey

@NotNull public final TableKey getTableKey()

Specified by:

getTableKey in interface TableLocation

Returns:

A TableKey instance for the enclosing table

getColumnLocation

@NotNull public final ColumnLocation getColumnLocation(@NotNull CharSequence name)

Specified by:

getColumnLocation in interface TableLocation

Parameters:

name - The column name

Returns:

The ColumnLocation for the defined column under this table location

as

public <T extends TableLocation> T as(Class<T> otherType)

Specified by:

as in interface TableLocation

isRealized

public final boolean isRealized()

Check if this location has been visited in a way that required creation of the actual underlying location/

Returns:

true of the location has been realized.
