Constructor Detail

### LinkSpatialIndex

    public LinkSpatialIndex(java.lang.String ssxFilename)
                     throws java.io.IOException

  Opens a spatial index file for reading.

Parameters:
  `ssxFilename` - the name of the spatial index file
Throws:
  `java.io.IOException` - if something goes wrong opening the file

### LinkSpatialIndex

    public LinkSpatialIndex(java.lang.String ssxFilename,
                            java.lang.String shpFilename)
                     throws java.io.IOException

  Opens a spatial index file and it's associated shape file.

Parameters:
  `ssxFilename` - the name of the spatial index file
  `shpFilename` - the name of the shape file
Throws:
  `java.io.IOException` - if something goes wrong opening the files

Method Detail

### makeESRIRecord

    public ESRIRecord makeESRIRecord(int shapeType,
                                     byte[] b,
                                     int off)
                              throws java.io.IOException

  Creates a record instance from the shape file data. Calls the appropriate record constructor based on the shapeType, and passes the buffer and offset to that constructor.

  Overrides:
    `makeESRIRecord` in class `SpatialIndex`
  Parameters:
    `shapeType` - the shape file's shape type, enumerated in `ShapeUtils`
    `b` - the buffer pointing to the raw record data
    `off` - the offset of the data starting point in the buffer
  Throws:
    `java.io.IOException` - if something goes wrong reading the file

    `ShapeUtils`
