- All Implemented Interfaces:
Processor<T>
- Direct Known Subclasses:
RowListProcessor
public abstract class AbstractListProcessor<T extends Context> extends java.lang.Object implements Processor<T>
A convenienceProcessor
implementation for storing all rows parsed into a list. A typical use case of this class will be:parserSettings.setRowProcessor(new RowListProcessor()); parser.parse(reader); // will invoke the
rowProcessed(String[], Context)
method for each parsed record. String[] headers = rowProcessor.getHeaders(); List<String[]> rows = rowProcessor.getRows();

AbstractListProcessor
public AbstractListProcessor()
Creates a new processor ofString[]
rows.
-
AbstractListProcessor
public AbstractListProcessor(int expectedRowCount)
Creates a new processor ofString[]
rows.- Parameters:
expectedRowCount
- expected number of rows to be parsed from the input. Used to pre-allocate the size of the outputList
returned bygetRows()

Method Detail

processStarted
public void processStarted(T context)
Description copied from interface:Processor
This method will by invoked by the parser once, when it is ready to start processing the input.- Specified by:
processStarted
in interfaceProcessor<T 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, T context)
Stores the row extracted by the parser into a list.- Specified by:
rowProcessed
in interfaceProcessor<T 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(T context)
Description copied from interface:Processor
This method will by invoked by the parser once, 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 interfaceProcessor<T extends Context>
- Parameters:
context
- A contextual object with information and controls over the state of the parsing process
-
getRows
public java.util.List<java.lang.String[]> getRows()
The list of parsed records- Returns:
- the list of parsed records
-
getHeaders
public java.lang.String[] getHeaders()
Returns the record headers. This can be either the headers defined inCommonSettings.getHeaders()
or the headers parsed in the file whenCommonSettings.getHeaders()
equals true- Returns:
- the headers of all records parsed.
