Parameters:

primitive - the primitive. Must not be null.

cmt - the modification type. Must not be null.

Throws:

java.lang.IllegalArgumentException - thrown if primitive is null

java.lang.IllegalArgumentException - thrown if cmt is null

contains

public boolean contains(PrimitiveId id)

Replies true if the changeset content contains the object with primitive id.

Parameters:

id - the id.

Returns:

true if the changeset content contains the object with primitive id

getModificationType

public ChangesetDataSet.ChangesetModificationType getModificationType(PrimitiveId id)

Replies the modification type for the object with id id. Replies null, if id is null or if the object with id id isn't in the changeset content.

Parameters:

id - the id

Returns:

the modification type

isCreated

public boolean isCreated(PrimitiveId id)

Replies true if the primitive with id id was created in this changeset. Replies false, if id is null.

Parameters:

id - the id

Returns:

true if the primitive with id id was created in this changeset.

isUpdated

public boolean isUpdated(PrimitiveId id)

Replies true if the primitive with id id was updated in this changeset. Replies false, if id is null.

Parameters:

id - the id

Returns:

true if the primitive with id id was updated in this changeset.

isDeleted

public boolean isDeleted(PrimitiveId id)

Replies true if the primitive with id id was deleted in this changeset. Replies false, if id is null.

Parameters:

id - the id

Returns:

true if the primitive with id id was deleted in this changeset.

getPrimitivesByModificationType

public java.util.Set<HistoryOsmPrimitive> getPrimitivesByModificationType(ChangesetDataSet.ChangesetModificationType cmt)

size

public int size()

Replies the number of objects in the dataset

Returns:

the number of objects in the dataset

getPrimitive

public HistoryOsmPrimitive getPrimitive(PrimitiveId id)
