Infinite loop in Vector.haveSharedCells(Vector)
-----------------------------------------------
Key: MAHOUT-223
URL: https://issues.apache.org/jira/browse/MAHOUT-223
Project: Mahout
Issue Type: Bug
Components: Matrix
Affects Versions: 0.2
Reporter: Jake Mannix
Fix For: 0.3
SparseVector:
{code}
@Override
public boolean haveSharedCells(Vector other) {
if (other instanceof SparseVector) {
return other == this;
} else {
return other.haveSharedCells(this);
}
}
{code}
DenseVector:
{code}
@Override
public boolean haveSharedCells(Vector other) {
if (other instanceof DenseVector) {
return other == this;
} else {
return other.haveSharedCells(this);
}
}
{code}
I think the result is self-explanatory.
I'd just check a fix in, but I don't have an svn account yet. Actually, no I
wouldn't because I'm not exactly sure what this method is supposed to do - it's
clearly for VectorView instances somehow... but what about Sparse and Dense
versions on the same vector (same meaning strictEquivalent() returns true for
them)?
