Method Details

getImplementationName

public String getImplementationName()

Description copied from interface: NamedImplementation

Get a name for the implementing class. Useful for abstract override Object.toString().

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

Specified by:

getImplementationName in interface NamedImplementation

Overrides:

getImplementationName in class CheckpointRecord

Returns:

A name for the implementing class

readDataFileState

protected void readDataFileState(@NotNull
 DataInputStream in)
                          throws IOException

Description copied from class: CheckpointRecord

Read data file state fields in to this record from a DataInputStream.

Overrides:

readDataFileState in class CheckpointRecord

Parameters:

in - The input stream

Throws:

IOException

clearDataFileSizeRecordOverrides

public void clearDataFileSizeRecordOverrides()

Replace any overridden DataFileSizeRecords with new mutable copies of the original records. This allows removing references to any higher level column data structures that may have been released.
