Field Detail

INHERIT

public static final DefinitionMode INHERIT

A record is in inherit mode when it is not defined in the current table. This implies that it inherits all its values from a parent record defined in an ancestor table.

DEFINE_ROOT

public static final DefinitionMode DEFINE_ROOT

A record is in root mode when it is locally defined in the current table and it does not inherit from a parent record.

DEFINE_OVERWRITE

public static final DefinitionMode DEFINE_OVERWRITE

The record is in overwriting mode when it is locally defined in the current table and it has a parent record with the same primary key.

The record then inherits its unspecified values from its parent record.

DEFINE_OCCULT

public static final DefinitionMode DEFINE_OCCULT

The record is in occulting mode to specify that the record with the same primary key is not inherited from the parent dataset. This implies that the resolved view of the table does not contain this record.

If a record in occulting mode is deleted, it becomes inherited if a record with the same primary key exists in the parent dataset (either root, overwriting or itself inherited).

Method Detail

isInherit

public boolean isInherit()

Returns true if this is the INHERIT state.

isRoot

public boolean isRoot()

Returns true if this is the DEFINE_ROOT state.

isOverwriting

public boolean isOverwriting()

Returns true if this is the DEFINE_OVERWRITE state.

isOcculting

public boolean isOcculting()

Returns true if this is the DEFINE_OCCULT state.

format

public String format()

Returns a persistent identifier for this definition mode.

The persistent identifier can be re-obtained by parsing using the method parse(String).

See Also:

parse(String)

parse

public static DefinitionMode parse(String aFlag)

Returns the definition mode that corresponds to the specified string.

The specified string must have been generated by the method format().

Throws:

IllegalArgumentException - if string specified is incorrect.

format()

getLabel

public String getLabel()

Returns a human-readable label for this definition mode.

toString

public String toString()

Overrides:

toString in class Object
