| Constructor Summary | |
| public | IndexedShapefileDataStore(URL url)
Creates a new instance of ShapefileDataStore. | | public | IndexedShapefileDataStore(URL url, URI namespace)
Creates a new instance of ShapefileDataStore. | | public | IndexedShapefileDataStore(URL url, URI namespace, boolean useMemoryMappedBuffer)
Creates a new instance of ShapefileDataStore. | | public | IndexedShapefileDataStore(URL url, boolean useMemoryMappedBuffer)
Creates a new instance of ShapefileDataStore. | | public | IndexedShapefileDataStore(URL url, boolean useMemoryMappedBuffer, boolean createIndex)
Creates a new instance of ShapefileDataStore. | | public | IndexedShapefileDataStore(URL url, URI namespace, boolean useMemoryMappedBuffer, boolean createIndex, byte treeType)

Creates a new instance of ShapefileDataStore. |
| Method Summary | |
| public void | buildQuadTree(int maxDepth)
Builds the QuadTree index. | | protected FeatureReader | createFeatureReader(String typeName, Reader r, FeatureType readerSchema)
| | protected String | createFeatureTypeName()
Create the type name of the single FeatureType this DataStore represents.
For example, if the urls path is file:///home/billy/mytheme.shp, the type
name will be mytheme. | | protected FeatureWriter | createFeatureWriter(String typeName, Transaction transaction)
Create a FeatureWriter for the given type name. | | protected void | finalize()
| | protected Reader | getAttributesReader(boolean readDbf, boolean readGeometry, Filter filter)
Returns the attribute reader, allowing for a pure shape reader, or a
combined dbf/shp reader. | | protected Envelope | getBounds(Query query)
| | protected String | getCurrentTypeName()
| | protected FeatureReader | getFeatureReader(String typeName, Query query)
Use the spatial index if available and adds a small optimization: if no
attributes are going to be read, don't uselessly open and read the dbf
file. | | public FeatureSource | getFeatureSource(String typeName)
| | public FeatureWriter | getFeatureWriterAppend(String typeName, Transaction transaction)
| | public FeatureType | getSchema(String typeName)
Obtain the FeatureType of the given name. | | public FeatureType | getSchema()
| | public String[] | getTypeNames()
Get an array of type names this DataStore holds.
ShapefileDataStore
will always return a single name. | | protected Filter | getUnsupportedFilter(String typeName, Filter filter)
| | public boolean | isIndexed()
Returns true if the indices already exist and do not need to be regenerated. | | public boolean | isLocal()
Determine if the location of this shape is local or remote. | | public boolean | isMemoryMapped()
| | protected DbaseFileReader | openDbfReader()
Convenience method for opening a DbaseFileReader. | | protected QuadTree | openQuadTree()
Convenience method for opening a QuadTree index. | | protected RTree | openRTree()
Convenience method for opening an RTree index. | | protected void | typeCheck(String requested)
A convenience method to check if a type name is correct. |
