Method Details

getByteOrder

ByteOrder getByteOrder()

Get the ByteOrder used by all FileDataBufferStores associated with this column location. Invoking this method is an error for any column location if ColumnLocation.exists() has not been invoked and returned true.

Returns:

The ByteOrder

getColumnFileBufferStore

@NotNull
@NotNull io.deephaven.shadow.enterprise.com.illumon.iris.db.v2.locations.FileDataBufferStore getColumnFileBufferStore(@NotNull
 @NotNull io.deephaven.shadow.enterprise.com.illumon.iris.db.v2.locations.ColumnFileType columnFileType)

Get the FileDataBufferStore for buffers from this column location for the specified ColumnFileType.

Parameters:

columnFileType - The ColumnFileType

Returns:

The buffer store for the specified column file type for this column location

symbolFileExists

boolean symbolFileExists()

Check if the symbol table file exists.

Returns:

true if the symbol data file exists.
