Class PartialThriftComparer<T extends TBase>

java.lang.Object

org.apache.thrift.partial.PartialThriftComparer<T>

public class PartialThriftComparer<T extends TBase>
extends Object

Enables comparison of two TBase instances such that the comparison is limited to the subset of fields defined by the supplied metadata.

This comparer is useful when comparing two instances where: -- one is generated by full deserialization. -- the other is generated by partial deserialization.

The typical use case is to establish correctness of partial deserialization.
