The CSV Socket Reader is an embedded adapter that reads CSV data from a socket. It closely resembles the CSV File Reader adapter.
Unlike the CSV File Reader adapter, though, this socket adapter reads input data from a TCP socket connected to a specified external address. Also unlike the file reader, the input source of this adapter is indefinite and naturally timed, so repetition and timing are not specified as properties.
| Property | Description |
|---|---|
| Host Name | The host or IP address to connect to. |
| Port | The TCP port to connect to. |
| Field Delimiter |
The delimiter used to separate tokens, defaults to a comma. Control
characters can be entered as &#ddd; where ddd is the character's ASCII value.
|
| String Quote Character | Matching pairs of the quote character delimit string constants. |
| Timestamp Format |
The format used to parse timestamp fields extracted from the input file. This
should be in the form expected by the java.text.SimpleDateFormat
class described in the Sun Java Platform SE reference documentation.
If a timestamp value is read that does not match the specified format
string, the entire record is discarded and a WARN message appears on the
console that includes the text |
| All Truncation Warnings |
DEPRECATED. String lengths were removed as of StreamBase 6.3.0, so this property is no longer necessary and should not be used in new instances of this adapter. This property is preserved in the adapter so that applications that defined it can continue to pass typechecking. |
| Schema (in the Edit Schemas tab) | Specifies the schema of the incoming CSV file. |
Typechecking will fail if the Delimiter or QuoteChar are not single character strings, or if the TimestampFormat is malformed.
On suspend, this adapter closes its input socket.
On resumption, it reconnects its socket and continues reading tuples from it.
This adapter does not leave its socket open during suspend because the input source is naturally timed, so the input source itself cannot be paused. Leaving the socket open could lead to buffering problems, ultimately causing the socket to close with an error.
