Method Detail

tableName

public String tableName()

Description copied from interface: Table

Gets the table name to write.

Specified by:

tableName in interface Table

Returns:

the table name

rowCount

public int rowCount()

Description copied from interface: Table

Gets the rows count to write.

Specified by:

rowCount in interface Table

Returns:

the rows count

columnCount

public int columnCount()

Description copied from interface: Table

Gets the columns count to write.

Specified by:

columnCount in interface Table

Returns:

the columns count

bytesUsed

public long bytesUsed()

Description copied from interface: Table

Gets the bytes used by the table.

Specified by:

bytesUsed in interface Table

Returns:

the bytes used by the table

addRow

public Table addRow(Object... values)

Description copied from interface: Table

Inserts one row with all columns.

The order of the values must be the same as the order of the schema.

Specified by:

addRow in interface Table

Parameters:

values - the values to insert

Returns:

this

subRange

public Table subRange(int fromIndex,
                      int toIndex)

Description copied from interface: Table

Gets a sub-range of the table.

Specified by:

subRange in interface Table

Parameters:

fromIndex - the start index

toIndex - the end index

Returns:

a sub-range of the table

complete

public Table complete()

Description copied from interface: Table

Completes the table data construction and prevents further row additions. After calling this method, the table will be immutable and ready to be written to the database.

This method must be called after all rows have been added to ensure any buffered rows are properly flushed to the underlying storage. Failure to call this method may result in data loss, particularly for implementations that use internal buffering.

Specified by:

complete in interface Table

Returns:

this

isCompleted

public boolean isCompleted()

Description copied from interface: Table

Checks if the table has been completed.

Specified by:

isCompleted in interface Table
