isEquivalent

public boolean isEquivalent(SandMessage sm)

Declared field equivalence check as specified by the SandMessage interface. String values are trimmed before comparison because conversions may occasionally result in trailing whitespace, which should not cause equivalence comparisons to fail. Comparisons are case insensitive since that corresponds to what most people expect, and how most databases work.

When comparing arrays, it is possible that the array elements may have been set to null as part of authorization filtering or similar unusual circumstances. A null array element is only equivalent to another null array element.
