org.deepsymmetry.cratedigger.pdb.RekordboxPdb.RowRef

Enclosing class:

RekordboxPdb

public static class RekordboxPdb.RowRef
extends io.kaitai.struct.KaitaiStruct

An offset which points to a row in the table, whose actual presence is controlled by one of the bits in `row_present_flags`. This instance allows the row itself to be lazily loaded, unless it is not present, in which case there is no content to be loaded.

Method Summary

Modifier and Type	Method	Description
RekordboxPdb.RowGroup	_parent()
RekordboxPdb	_root()
io.kaitai.struct.KaitaiStruct	body()	The actual content of the row, as long as it is present.
Integer	ofsRow()	The offset of the start of the row (in bytes past the end of the page header).
Boolean	present()	Indicates whether the row index considers this row to be present in the table.
Integer	rowBase()	The location of this row relative to the start of the page.
int	rowIndex()	Identifies which row within the row index this reference came from, so the correct flag can be checked for the row presence and the correct row offset can be found.

Method Detail

ofsRow

public Integer ofsRow()

The offset of the start of the row (in bytes past the end of the page header).

rowBase

public Integer rowBase()

The location of this row relative to the start of the page. A variety of pointers (such as all device_sql_string values) are calculated with respect to this position.

present

public Boolean present()

Indicates whether the row index considers this row to be present in the table. Will be `false` if the row has been deleted.

body

public io.kaitai.struct.KaitaiStruct body()

The actual content of the row, as long as it is present.

rowIndex

public int rowIndex()

Identifies which row within the row index this reference came from, so the correct flag can be checked for the row presence and the correct row offset can be found.

_root

public RekordboxPdb _root()

_parent

public RekordboxPdb.RowGroup _parent()
