Class MIFDataStore

java.lang.Object
  org.geotools.data.AbstractDataStore
      org.geotools.data.mif.MIFDataStore

All Implemented Interfaces:

DataStore

public class MIFDataStore

extends AbstractDataStore

MIFDataStore gives read and write access to MapInfo MIF files. It can be instantiated either on a single .mif file, or on a directory (thus exposing all the mif files within).

MIFDataStore is a replacement for the MapInfoDataStore, which was based on the legacy MapInfoDataSource.

Constructor Detail

MIFDataStore

public MIFDataStore(java.lang.String path,
                    java.util.HashMap params)
             throws java.io.IOException

Builds a new MIFDataStore given a mif file or directory path.

Each feature type is represented by a MIFFile object

Parameters:

path - location (directory) of the mif files to read, or full path of a single mif file. If a directory is given, the headers of all the mif files in it are read.

params - The MIFFile parameters map, see MIFFile for a full description.

Throws:

java.io.IOException - Path does not exists, or error accessing files

See Also:

MIFFile.MIFFile(String, Map)
