Write TCP Data
Write TCP Data is an asynchronous activity that sends data on the specified TCP connection. The connection must be opened by an activity or process starter that executed previously in the process.
General
The General tab has the following fields.
| Field | Literal Value/Module Property/Process Property | Description |
|---|---|---|
| Name | None | The name to be displayed as the label for the activity in the process. |
| Type | None | The type of the data to write. This can be either
Text or
Binary.
Specifying Text in this field displays the Separator and Encoding fields. Specifying Binary in this field displays the User Defined Separator field. |
| Separator | Yes | The type of separator to use. The separator is written to the TCP connection after the specified data is written.
Select User-defined separator from the drop-down list to enable the User Defined Separator field. |
| User Defined Separator | Yes | This field specifies the separator character to use.
When Binary is selected in the Type field, a user-defined separator can be a string representation of a single byte value or it can be comma-separated byte values (for example, 0x0a, 0x0b, 0x0c). For valid string representations of byte value, refer to the Java documentation for the decode(String n) method of java.lang.Byte. |
| Encoding | Yes | When text data is specified, this field determines the character encoding to use for the text data. |
Input
The following is the input for activity.
| Input Item | Datatype | Description |
|---|---|---|
| connection | binary | The handle to the connection that you want to write data to. This connection is obtained from a previously executed activity in the process that opened the connection. |
| data | string or binary | The data to write to the TCP connection. The data type of this field is either String or Binary, depending upon the data selected in the Type field in the General tab. |
| encoding | string | An optional element. When writing text data, this specifies the character encoding of the text. This value overrides the value specified in the Encoding field in the General tab. |
| separator | binary | An optional element. This is available only when you select the s option on the General tab. |
| timeout | number | An optional element. The time to wait (in milliseconds) for this activity to complete. |
