Scala


Several extensions to the XAP API have been introduced to provide a more natural way of combining Scala with XAP.


  • Constructor based properties
    The com.gigaspaces.annotation.pojo.SpaceClassConstructor annotation on a constructor will cause the data class properties analysis to be based on properties found in the constructor (instead of getters/setters).

  • Enhanced REPL
    Following is a short demo of what can be done with the XAP scala shell. It should be noted that this shell is a regular Scala REPL with some initial imports and initialization code.

  • Predicate based queries
    Support for predicate based queries on the GigaSpace proxy has been in added. This support is based on the new macros feature introduced in Scala.

  • Scripting Executor
    Dynamic Language Tasks has been extended and now supports Scala based script execution.

  • Task Execution
    A wrapper around the XAP API provides some sugaring on top of the GigaSpace#execute methods.


The Scala version required in order to use the Scala Openspaces extension is 2.10.x

Assuming there is a scala installation under $SCALA_HOME, the jars under $SCALA_HOME/lib should be copied to $GS_HOME/lib/platform/scala/lib. Another options is to change setenv.{bat,sh} so that $SCALA_JARS points to $SCALA_HOME/lib.
