srcInfo - The source meta-information.

dstInfo - The destination meta-information.

MessageComparator

public MessageComparator(MessageInfoProvider srcProvider,
                         MessageInfoProvider dstProvider)

Creates a new comparator for the given meta-information providers.

Parameters:

dstProvider - The destination meta-information provider.

MessageComparator

public MessageComparator(ContainerClassInfo classInfo)
                  throws I18NException

Parameters:

classInfo - The meta-information of a container class.

Throws:

I18NException - Thrown if there is a problem obtaining the meta-information of the properties file.

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.
