Constructor Detail

CompositeProcessor

public CompositeProcessor(Processor... processors)

Creates a new CompositeProcessor with the list of Processor implementations to be used.

Parameters:

processors - the sequence of Processor implementations to be used.

Method Detail

processStarted

public void processStarted(C context)

Initializes each Processor used by this class. This is invoked by the parser once, when it is ready to start processing the input.

Specified by:

processStarted in interface Processor<C extends Context>

Parameters:

context - A contextual object with information and controls over the current state of the parsing process

rowProcessed

public void rowProcessed(java.lang.String[] row,
                         C context)

Invoked by the parser after all values of a valid record have been processed. All Processor implementations will have their corresponding Processor.rowProcessed(String[], Context) method called with the given row.

Specified by:

rowProcessed in interface Processor<C extends Context>

Parameters:

row - the data extracted by the parser for an individual record. Note that:

• it will never by null.
• it will never be empty unless explicitly configured using CommonSettings.setSkipEmptyLines(boolean)
• it won't contain lines identified by the parser as comments. To disable comment processing set Format.setComment(char) to '\0'

context - A contextual object with information and controls over the current state of the parsing process

processEnded

public void processEnded(C context)

This method will by invoked by the parser once for each Processor used by this class, after the parsing process stopped and all resources were closed.

It will always be called by the parser: in case of errors, if the end of the input us reached, or if the user stopped the process manually using Context.stop().

Specified by:

processEnded in interface Processor<C extends Context>

Parameters:

context - A contextual object with information and controls over the state of the parsing process
