Field Summary

Fields

Modifier and Type	Field	Description
private static java.lang.String[]	EMPTY_STRING_ARRAY
private java.util.List<CommandInteger>	geometry	The geometry of the feature.
private static byte	GEOMETRY_FIELD
private static byte	GEOMETRY_TYPE_FIELD
private Geometry	geometryObject
private GeometryTypes	geometryType	The geometry type of the feature.
private long	id	The id of the feature.
private static byte	ID_FIELD
private static java.text.NumberFormat	NUMBER_FORMAT	The number format instance to use (using a static instance gets rid of quite o few allocations) Doing this reduced the allocations of parseTagValue(String, Layer, int, List) from 22.79% of parent to 12.2% of parent.
private static byte	TAG_FIELD
private TagMap	tags	The tags of the feature.

Constructor Detail

Feature

public Feature(Layer layer,
               ProtobufRecord protobufRecord)
        throws java.io.IOException

Create a new Feature

Parameters:

layer - The layer the feature is part of (required for tags)

protobufRecord - The record to create the feature from

Throws:

java.io.IOException - - if an IO error occurs

Method Detail

parseTagValue

private static java.lang.String parseTagValue(java.lang.String key,
                                              Layer layer,
                                              int number,
                                              java.util.List<java.lang.String> tagList)

Parse a tag value

Parameters:

key - The current key (or null, if null, the returned value will be the new key)

layer - The layer with key/value information

number - The number to get the value from

tagList - The list to add the new value to

Returns:

The new key (if null, then a value was parsed and added to tags)

getGeometry

public java.util.List<CommandInteger> getGeometry()

Get the geometry instructions

Returns:

The geometry

getGeometryType

public GeometryTypes getGeometryType()

Get the geometry type

Returns:

The GeometryTypes

getId

public long getId()

Get the id of the object

Returns:

The unique id in the layer, or 0.

getTags

public TagMap getTags()

Get the tags

Returns:

A tag map

getGeometryObject

public Geometry getGeometryObject()

Get the an object with shapes for the geometry

Returns:

An object with usable geometry information

Throws:

java.lang.IllegalArgumentException - if the geometry object cannot be created because arguments are not understood or the shoelace formula returns 0 for a polygon ring.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
