readCsv

@ScriptApi
public static Table readCsv(InputStream is,
 String format)
                     throws IOException

Returns a memory table created by importing CSV data. The first row must be column names. Column data types are inferred from the data.

Parameters:

is - an InputStream providing access to the CSV data.

format - an Apache Commons CSV format name to be used to parse the CSV, or a single non-newline character to use as a delimiter.

Returns:

a Deephaven Table object

Throws:

IOException - if the InputStream cannot be read

readCsv

@ScriptApi
public static Table readCsv(InputStream is,
 String format,
 StatusCallback progress)
                     throws IOException

Parameters:

is - an InputStream providing access to the CSV data.

format - an Apache Commons CSV format name to be used to parse the CSV, or a single non-newline character to use as a delimiter.

progress - a StatusCallback object that can be used to log progress details or update a progress bar. If passed explicitly as null, a StatusCallback instance will be created to log progress to the current logger.

Returns:

a Deephaven Table object

Throws:

IOException - if the InputStream cannot be read
