    Cloneable, Serializable

      public interface JCoFunction
      extends Cloneable, Serializable

  Class that represents a function. A function instance consists of a name, an import parameter list, a changing parameter list, an export parameter list and a table parameter list. Moreover, it can have a list of AbapExceptions.

          JCoParameterList getExportParameterList()

      Returns the list of export parameters.
      Returns:
        the export parameters or `null` if the function does not have any export parameters

    - #### getChangingParameterList

          JCoParameterList getChangingParameterList()

      Returns the list of changing parameters.
      Returns:
        the export parameters or `null` if the function does not have any changing parameters

    - #### getTableParameterList

          JCoParameterList getTableParameterList()

      Returns the list of table parameters.
      Returns:
        the table parameters or `null` if the function does not have any table parameters

    - #### getExceptionList

          AbapException[] getExceptionList()

      Returns the list of defined ABAP exceptions that can occur.
      Returns:
        the list of exceptions or `null` if the function does not have any defined ABAP runtime exceptions

    - #### getException

          AbapException getException(String key)

      Returns the ABAP exception for the specified key.
      Parameters:
        `key` - ABAP's error key
      Returns:
        the ABAP exception for the specified key or `null` if not defined

    - #### setAbapClassExceptionMode

          void setAbapClassExceptionMode(AbapClassException.Mode mode)

      Sets the mode for ABAP class exceptions. Enabling means that the ABAP server is permitted to transmit an ABAP class exception, whereas disabling signifies that the server must not transmit such an exception.
      Parameters:
        `mode` - the value determining whether ABAP class exceptions are permitted (full or limited to the exception chain) or not

    - #### isAbapClassExceptionEnabled

          boolean isAbapClassExceptionEnabled()

      Returns the boolean value that indicates whether or not the server is permitted to transmit an ABAP class exception when executing this function.
      Returns:
        `true` or `false` depending on whether transmitting ABAP class exceptions is permitted or not, respectively

    - #### execute

          void execute(JCoDestination destination)
                       throws JCoException

      Executes the function on the given target destination synchronously.
      Parameters:
        `destination` - the destination on which the function module should be executed
      Throws:
        `JCoException` - if an exception occurred during the call execution

    - #### execute

          void execute(JCoDestination destination,
                     String tid)
                       throws JCoException

      Executes the function on the given target destination in transactional mode using the tRfc protocol.
      Parameters:
        `destination` - the destination on which the function module should be executed
        `tid` - the transaction ID to use for the tRFC call
      Throws:
        `JCoException` - if an exception occurred during the call execution

    - #### execute

          void execute(JCoDestination destination,
                     String tid,
                     String queueName)
                       throws JCoException

      Executes the function on the given target destination in queued transactional mode using the qRfc protocol.
      Parameters:
        `destination` - the destination on which the function module should be executed
        `tid` - the transaction ID to use for the qRFC call
        `queueName` - the inbound queue to use for the qRFC call
      Throws:
        `JCoException` - if an exception occurred during the call execution

    - #### toXML

          String toXML()

      Returns the function as an XML string. Its format is depending on the used interface implementation, and is not guaranteed to remain stable.This method is meant to be used as a more powerful toString() variant, which allows to view the function within XML viewing tools thus making it easier to have a closer look at single parameter values.
      Please note, that only an XML fragment is returned, which does not include an XML header.
      Returns:
        the function serialized in XML format

    - #### getFunctionTemplate

          JCoFunctionTemplate getFunctionTemplate()

      Returns the function template, i.e. the description of the function and its parameters, which was used to create this function instance.
      Returns:
        the function template
