Class CSVSaveService
public final class CSVSaveService
This class provides a means for saving/reading test results as CSV files.
static String[] | csvReadFile(BufferedReader infile, char delim) - Reads from file and splits input into strings according to the delimiter,
taking note of quoted strings.
|
static String[] | csvSplitString(String line, char delim) - Reads from String and splits into strings according to the delimiter,
taking note of quoted strings.
|
static SampleSaveConfiguration | getSampleSaveConfiguration(String headerLine, String filename) - Parse a CSV header line
|
static SampleEvent | makeResultFromDelimitedString(String inputLine, SampleSaveConfiguration saveConfig, long lineNumber) - Does not handle quoted strings; use
processSamples(String,Visualizer,ResultCollector) instead
|
static String | printableFieldNamesToString() - Generates the field names for the output file
|
static String | printableFieldNamesToString(SampleSaveConfiguration saveConfig) - Generates the field names for the output file
|
static void | processSamples(String filename, Visualizer visualizer, ResultCollector resultCollector) - Read Samples from a file; handles quoted strings.
|
static String | resultToDelimitedString(SampleEvent event) - Convert a result into a string, where the fields of the result are
separated by the default delimiter.
|
static String | resultToDelimitedString(SampleEvent event, String delimiter) - Convert a result into a string, where the fields of the result are
separated by a specified String.
|
static void | saveCSVStats(DefaultTableModel model, FileWriter writer) - Method saves aggregate statistics as CSV from a table model.
|
static void | saveCSVStats(Vector data, FileWriter writer) - Method will save aggregate statistics as CSV.
|
static void | saveCSVStats(Vector data, FileWriter writer, headers[] ) - Method will save aggregate statistics as CSV.

QUOTING_CHAR
public static final char QUOTING_CHAR
csvReadFile
public static String[] csvReadFile(BufferedReader infile,
char delim)
throws IOException
Reads from file and splits input into strings according to the delimiter,
taking note of quoted strings.
Handles DOS (CRLF), Unix (LF), and Mac (CR) line-endings equally.
N.B. a blank line is returned as a zero length array, whereas "" is returned
as an empty string. This is inconsistent.
infile
- input file - must support mark(1)delim
- delimiter (e.g. comma)
csvSplitString
public static String[] csvSplitString(String line,
char delim)
throws IOException
Reads from String and splits into strings according to the delimiter,
taking note of quoted strings.
Handles DOS (CRLF), Unix (LF), and Mac (CR) line-endings equally.
line
- input linedelim
- delimiter (e.g. comma)
getSampleSaveConfiguration
public static SampleSaveConfiguration getSampleSaveConfiguration(String headerLine,
String filename)
Parse a CSV header line
headerLine
- from CSV filefilename
- name of file (for log message only)
- config corresponding to the header items found or null if not a header line
printableFieldNamesToString
public static String printableFieldNamesToString()
Generates the field names for the output file
- the field names as a string
printableFieldNamesToString
public static String printableFieldNamesToString(SampleSaveConfiguration saveConfig)
Generates the field names for the output file
- the field names as a string
processSamples
public static void processSamples(String filename,
Visualizer visualizer,
ResultCollector resultCollector)
throws IOException
Read Samples from a file; handles quoted strings.
filename
- input filevisualizer
- where to send the resultsresultCollector
- the parent collector
resultToDelimitedString
public static String resultToDelimitedString(SampleEvent event)
Convert a result into a string, where the fields of the result are
separated by the default delimiter.
event
- the sample event to be converted
- the separated value representation of the result
resultToDelimitedString
public static String resultToDelimitedString(SampleEvent event,
String delimiter)
Convert a result into a string, where the fields of the result are
separated by a specified String.
event
- the sample event to be converteddelimiter
- the separation string
- the separated value representation of the result
saveCSVStats
public static void saveCSVStats(DefaultTableModel model,
FileWriter writer)
throws IOException
Method saves aggregate statistics as CSV from a table model.
Same as saveCSVStats(Vector, FileWriter, String[])
except
that there is no need to create a Vector containing the data.
model
- table model containing the datawriter
- output file
saveCSVStats
public static void saveCSVStats(Vector data,
FileWriter writer)
throws IOException
Method will save aggregate statistics as CSV. For now I put it here.
Not sure if it should go in the newer SaveService instead of here.
if we ever decide to get rid of this class, we'll need to move this
method to the new save service.
data
- vector of data rowswriter
- output file
saveCSVStats
public static void saveCSVStats(Vector data,
FileWriter writer,
headers[] )
throws IOException

Not sure if it should go in the newer SaveService instead of here.
if we ever decide to get rid of this class, we'll need to move this
method to the new save service.
data
- vector of data rowswriter
- output file
