Method Details

process

protected void process(InputStream content,
 String mimeType)

Do not override this method unless you want to process the file yourself.

Overrides:

process in class UploadProcessorView

Parameters:

content - File stream.

mimeType - Mime type.

setProcessor

public void setProcessor(BiConsumer<InputStream,String> processor)

Overrides:

setProcessor in class UploadProcessorView

setMaxFiles

public void setMaxFiles(int fileCount)

Overrides:

setMaxFiles in class UploadProcessorView

setProcessor

public void setProcessor(Consumer<String[]> csvConsumer)

process

protected void process(String[] csvEntry)

Override this method for processing the "CSV Entries". Each "CSV Entry" - 1 per line - will be passed here as a string array unless a "Processor" (Consumer) is set and in that case, Processor's accept() method (Consumer.accept(Object)) will be called with each CSV entry.

Parameters:

csvEntry - CSV entry to consume.

getLineNumber

public int getLineNumber()

Get the line number of the line being processed currently.

Returns:

Line number if available, otherwise, -1.

processCompleted

protected void processCompleted()

This will be invoked when the processing is completed.
