testSerializationAfterFilterCellPreservesBehavior

@Test
public void testSerializationAfterFilterCellPreservesBehavior()
                                                       throws Exception

Serializing a filter must not leak the internal mask encoding. On the unsafe path the stored mask is {-1 (fixed), 0 (non-fixed)}; toByteArray must emit the public constructor {0, 1} form so the round-tripped filter behaves identically (otherwise the leaked {-1, 0} is reparsed as an all-fixed mask). Processing a cell first must not change this.

Throws:

Exception

testEqualsConsistentAfterFilterCell

@Test
public void testEqualsConsistentAfterFilterCell()

Two filters built from the same rule (distinct array instances) must be equal and hash equally, i.e. equals/hashCode must be content-based, not identity-based, and consistent with each other and with the serialized ({0, 1}) form. This must also hold after one of them has processed a cell.
