Description
This GreenVulcano® ESB element specifies a modification of a data buffer.
VulCon / GV Console Configuration
A change to a data buffer is to set one or more fields of the buffer with configurable values, or perform some transformation on the body. You can also completely remove the body field.
The ChangeGVBuffer Element is used by ChangeGVBufferNode, GVEndNode, ServiceCallerTask, GVWebServices, test-service-call. Its attributes are:
| Attribute | Type | Description |
|---|---|---|
| clear-data | required | This attribute can be set to:
|
| system | optional | This attribute sets the value of system field of the buffer. |
| service | optional | This attribute sets the value of service field of the buffer. |
| ret-code | optional | This attribute sets the value of return code field of the buffer. |
| crypto-op | optional | This attribute defines whether or not to use encryption and if you encrypt or decrypt the body field. Can not be defined with compress-op, scope-name, base64-op and clear-data. The attribute's admitted values are:
|
| key-id | optional | This attribute sets the key to use for the encryption/decryption. |
| compress-op | optional | This attribute defines whether to use compression and if you compress or decompress the body field. Can not be defined with crypto-op, scope-name, base64-op and clear-data. The attribute's admitted values are:
|
| compress-level | optional | This attribute sets the compression ratio to use. The attribute's admitted values are:
|
| base64-op | optional | This attribute defines whether to use Base64 encoding and if you encode or decode the body field. Can not be defined with compress-op, crypto-op, scope-name and clear-data. The attribute's admitted values are:
|
| scope-name | optional | This attribute defines whether to use a JavaScript. If it is defined, represent the 'scope' to be used for script execution. The execution environment map is added to the scope as environment, the current input object is added to the scope as data. Can not be defined with compress-op, crypto-op, base64-op and clear-data. REMOVED in v3.5 |
| script-file | optional | This attribute is the name of the file containing the script to run. REMOVED in v3.5 |
It has the following subelements:
- Description
- SimpleGVBufferBodyBuilder
- Script: define a JavaScript script. REPLACED in v3.5 by a GENERIC SCRIPT CONTAINER
- OGNLScript: define an OGNL script. REMOVED in v3.5
- PropertyDef: define a property to set in GVBuffer.
SimpleGVBufferBodyBuilder
This element allows you to set the GVBuffer body.
Its attributes are:
| Attribute | Type | Description |
|---|---|---|
| type | fixed | body-builder. |
| class | fixed | it.greenvulcano.gvesb.internal.data.SimpleGVBufferBodyMaker |
| file-name | optional | This attribute is the path of a file whose contents should be inserted into the body of GVBuffer. You can specify a file on the server's classpath using the following syntax: CP://filename or cp://filename This attribute has precedence over the element content. |
| read-once | optional | If true the file will be read only once, otherwise the file will be read on each invocation of the service. This attribute is meaningful only if the attribute file-name is specified. Default to "true". |
| encoding | optional | This attribute is the encoding used to convert text to byte array. The attribute's admitted values are:
|
| process-metadata | optional | If true the body content can contain metadata to be resolved at runtime. The body content must be a valid String. Default to false. The attribute's admitted values are:
