cachedBBox

private BBox cachedBBox

Constructor Detail

VectorRelation

public VectorRelation(java.lang.String layer)

Create a new relation for a layer

Parameters:

layer - The layer the relation will belong to

Method Detail

getIdGenerator

public UniqueIdGenerator getIdGenerator()

Description copied from class: AbstractPrimitive

Returns the unique identifier generator.

Specified by:

getIdGenerator in class AbstractPrimitive

Returns:

the unique identifier generator

accept

public void accept(PrimitiveVisitor visitor)

Description copied from interface: IPrimitive

Makes the given visitor visit this primitive.

Specified by:

accept in interface IPrimitive

Parameters:

visitor - visitor

getBBox

public BBox getBBox()

Description copied from interface: IPrimitive

Fetches the bounding box of the primitive. Since 17752, the returned bounding box might be immutable, i.e., modifying calls throw an UnsupportedOperationException.

Specified by:

getBBox in interface IPrimitive

Specified by:

getBBox in interface IQuadBucketType

Returns:

Bounding box of the object

addRelationMember

protected void addRelationMember(VectorRelationMember member)

removeRelationMember

protected void removeRelationMember(VectorRelationMember member)

Remove the first instance of a member from the relation

Parameters:

member - The member to remove

getMembersCount

public int getMembersCount()

Description copied from interface: IRelation

Returns the number of members.

Specified by:

getMembersCount in interface IRelation<VectorRelationMember>

Returns:

number of members

getMember

public VectorRelationMember getMember(int index)

Description copied from interface: IRelation

Returns the relation member at the specified index.

Specified by:

getMember in interface IRelation<VectorRelationMember>

Parameters:

index - the index of the relation member

Returns:

relation member at the specified index

getMembers

public java.util.List<VectorRelationMember> getMembers()

Description copied from interface: IRelation

Returns members of the relation.

Specified by:

getMembers in interface IRelation<VectorRelationMember>

Returns:

Members of the relation. Changes made in returned list are not mapped back to the primitive, use IRelation.setMembers(java.util.List<M>) to modify the members

setMembers

public void setMembers(java.util.List<VectorRelationMember> members)

Description copied from interface: IRelation

Sets members of the relation.

Specified by:

setMembers in interface IRelation<VectorRelationMember>

Parameters:

members - Can be null, in that case all members are removed

getMemberId

public long getMemberId(int idx)

Description copied from interface: IRelation

Returns id of the member at given index.

Specified by:

getMemberId in interface IRelation<VectorRelationMember>

Parameters:

idx - member index

Returns:

id of the member at given index

getRole

public java.lang.String getRole(int idx)

Description copied from interface: IRelation

Returns role of the member at given index.

Specified by:

getRole in interface IRelation<VectorRelationMember>

Parameters:

idx - member index

Returns:

role of the member at given index

getMemberType

public OsmPrimitiveType getMemberType(int idx)

Description copied from interface: IRelation

Returns type of the member at given index.

Specified by:

getMemberType in interface IRelation<VectorRelationMember>

Parameters:

idx - member index

Returns:

type of the member at given index

getType

public OsmPrimitiveType getType()

Description copied from interface: PrimitiveId

Gets the type of object represented by this object. Note that this should return the base primitive type (OsmPrimitiveType.NODE, OsmPrimitiveType.WAY, and OsmPrimitiveType.RELATION).

Specified by:

getType in interface PrimitiveId

Returns:

the object type
