Method Detail

toString
public java.lang.String toString()
Returns a string representation of the object. This will return a brief description of the format read by this reader.- Overrides:
toString
in classjava.lang.Object
- Returns:
- A brief description of the format read by this reader.
-
getExtension
public java.lang.String getExtension()
Returns the preferred file extension (not including the ".") for files of this GeomReader's type.- Returns:
- The preferred extension for this file type.
-
canReadData
public int canReadData(java.io.File inputFile) throws java.io.IOException
Method that determines if this reader can read paneled geometry from the specified input file.- Specified by:
canReadData
in interfaceGeomReader
- Overrides:
canReadData
in classAbstractGeomReader
- Parameters:
inputFile
- The input file containing the geometry to be read in.- Returns:
- GeomReader.NO if the file format is not recognized by this reader. GeomReader.YES if the file format is definitely recognized by this reader. GeomReader.MAYBE if the file format might be readable by this reader, but that can't easily be determined without actually reading the file.
- Throws:
java.io.IOException
- If there is a problem reading from the specified file.
-
read
public PointVehicle read(java.io.File inputFile) throws java.io.IOException
Reads in a POINTS (POI) geometry file from the specified input file and returns aPointVehicle
object that contains the geometry from the POI file.Each component will have an Integer stored in the user data under the key "A502A633TypeCode" that contains the A502-A633 array type code for all the networks contained in that component.
WARNING: This file format is not unit aware. You must set the units to be used by calling "setFileUnits()" before calling this method!
- Specified by:
read
in interfaceGeomReader
- Overrides:
read
in classAbstractGeomReader
- Parameters:
inputFile
- The input file containing the geometry to be read in. May not be null.- Returns:
- A
PointVehicle
object containing the geometry read in from the file. If the file has no geometry in it, then this list will have no components in it (will have a size() of zero). - Throws:
java.io.IOException
- If there is a problem reading the specified file.- See Also:
AbstractGeomReader.setFileUnits(javax.measure.unit.Unit)
-
isUnitAware
public boolean isUnitAware()
This method always returnsfalse
as POI files do not encode the units that are being used. You must callsetFileUnits
to set the units being used before reading from a file of this format.- Returns:
- This implementation always returns false.
