Constructor Detail

AbstractFileSetCheck

public AbstractFileSetCheck()

Method Detail

destroy

public void destroy()

Description copied from interface: FileSetCheck

Cleans up the object.

Specified by:

destroy in interface FileSetCheck

See Also:

FileSetCheck

getCharset

public String getCharset()

Returns:

the name of the charset

setCharset

public void setCharset(String aCharset)
                throws UnsupportedEncodingException

Sets a named charset.

Parameters:

aCharset - the name of a charset

Throws:

UnsupportedEncodingException - if aCharset is unsupported.

setMessageDispatcher

public final void setMessageDispatcher(MessageDispatcher aDispatcher)

Sets the MessageDispatcher that is used to dispatch error messages to AuditListeners during processing.

Specified by:

setMessageDispatcher in interface FileSetCheck

Parameters:

aDispatcher - the dispatcher

getMessageDispatcher

protected final MessageDispatcher getMessageDispatcher()

A message dispatcher is used to fire violation messages to interested audit listeners.

Returns:

the current MessageDispatcher.

filter

protected final File[] filter(File[] aFiles)

Determines the set of files this FileSetCheck is interested in. Returns the files that have one of the currently active file extensions. If no file extensions are active the argument array is returned.

This method can be used in the implementation of process() to filter it's argument list for interesting files.

Parameters:

aFiles - the candidates for processing

Returns:

the subset of aFiles that this FileSetCheck should process

See Also:

FileSetCheck.process(java.io.File[])

setFileExtensions

public final void setFileExtensions(String[] aExtensions)

Sets the file extensions that identify the files that pass the filter of this FileSetCheck.

Parameters:

aExtensions - the set of file extensions. A missing initial '.' character of an extension is automatically added.

getMessageCollector

protected final LocalizedMessages getMessageCollector()

Returns the collector for violation messages. Subclasses can use the collector to find out the violation messages to fire via the message dispatcher.

Returns:

the collector for localized messages.

log

protected final void log(int aLine,
                         String aKey,
                         Object[] aArgs)

Adds a violation message to the message collector. Log a message that has no column information.

Specified by:

log in class AbstractViolationReporter

Parameters:

aLine - the line number where the error was found

aKey - the message that describes the error

aArgs - the details of the message

See Also:

MessageFormat

log

protected final void log(int aLineNo,
                         int aColNo,
                         String aKey,
                         Object[] aArgs)

Adds a violation message to the message collector. Log a message that has column information.

Specified by:

log in class AbstractViolationReporter

Parameters:

aLineNo - the line number where the error was found

aColNo - the column number where the error was found

aKey - the message that describes the error

aArgs - the details of the message

MessageFormat

fireErrors

protected final void fireErrors(String aFileName)

Notify all listeners about the errors in a file. Calls MessageDispatcher.fireErrors() with all logged errors and than clears errors' list.

Parameters:

aFileName - the audited file
