Constructor Detail

ArcGridReader

public ArcGridReader(java.lang.Object aSource)

Creates a new instance of an ArcGridReader. Creates a new instance of an ArcGridReader basing the decision on whether the file is compressed or not. I assume nothing about file extension.

Parameters:

aSource - Source object for which we wnat to build an ArcGridReader.
