dstProvider - The destination meta-information provider.

MessageComparator

public MessageComparator(ContainerClassInfo classInfo)
                  throws I18NException

Method Detail

getMismatches

public MessageInfoPair[] getMismatches()

Returns:

The mismatches.

getExtraSrcInfo

public MessageInfo[] getExtraSrcInfo()

Returns the receiver's list of source meta-information that is absent from the destination.

Returns:

The list.

getExtraDstInfo

public MessageInfo[] getExtraDstInfo()

Returns the receiver's list of destination meta-information that is absent from the source.

Returns:

The list.

isMatch

public boolean isMatch()

Checks whether the receiver found no differences between source and destination.

Returns:

True if so.

getDifferences

public String getDifferences()

Returns a textual form of the differences between source and destination.
