Ok Martin I got a couple of improvments for tiling but now I have a
suggestion for improving the equals method on general envelope. What
do you think about this one?
/**
* Compares the specified object with this envelope for equality.
*/
public boolean equals(final Object object) {
if (object != null && object.getClass().equals(getClass())) {
final GeneralEnvelope that = (GeneralEnvelope) object;
if (this.getDimension() != that.getDimension())
return false;
final int dim = this.getDimension();
double firstLength;
double secondLength;
double firstCoord;
double secondCoord;
final int length = ordinates.length;
for (int i = 0; i < length; i++) {
// check lengths
firstLength = Math.abs(ordinates[(i + dim) %
length]
- ordinates[i]);
secondLength = Math.abs(that.ordinates[(i +
dim) % length]
- that.ordinates[i]);
if (Math.abs((firstLength - secondLength)
/ Math.min(firstLength,
secondLength)) > EPS)
return false;
//coords
firstCoord=ordinates[(i + dim) % dim];
secondCoord=ordinates[(i + dim) % dim];
if (Math.abs((firstCoord - secondCoord)
/ Math.min(firstLength,
secondLength)) > EPS)
return false;
}
return Utilities.equals(this.crs, that.crs);
}
return false;
}
