# DSQL map features

Talend Data Mapper provides a few features in DSQL maps on top of the existing Data Shaping Language functions.

You can find the documentation for the other Data Shaping Language functions in the [Talend Data Shaping Language Reference Guide](https://help.qlik.com/talend/en-US/data-shaping-language-reference-guide/8.0).

## getContextVariable

You can use the getContextVariable function to call a context variable defined in your Talend Studio Job.

## java:call

Calls a Java method.

You can use the java:call feature to call a Java method. This can be used to call beans and routines available in Talend Studio for example.

### Arguments

Java parameters.

Three different syntaxes are supported:

* Call to a static method: java:call(<class\_name>, <method\_name>, <arguments>)
* Call to a non-static method: java:call(java:new(<class\_name>, <constructor\_arguments>), <method\_name>, <arguments>)
* Call to a non-static method of a Java object returned by another method of a Java object: java:call(java:call(<class\_name>, <method\_name>, <arguments>), <method\_name>, <arguments>)
