startConsumingImpl

protected void startConsumingImpl(Entity entity)

Description copied from class: TextFileExporter

Writes the data to the output file. It uses the parent class settings for rendering the object. Overwrite this in a child class for custom output formats.

Overrides:

startConsumingImpl in class TextFileExporter<Entity>

Parameters:

entity - the data object to output

postInitPrinter

protected void postInitPrinter(Entity entity)

Description copied from class: TextFileExporter

This method is called after printer initialization and before writing the first data entry. Overwrite this method in child classes e.g. for writing a file header.

Overrides:

postInitPrinter in class TextFileExporter<Entity>

Parameters:

entity - the first data item to write to the file
