## Class JavaSamplerContext

- java.lang.Object
- - org.apache.jmeter.protocol.java.sampler.JavaSamplerContext

-     public class JavaSamplerContext
      extends Object

  JavaSamplerContext is used to provide context information to a JavaSamplerClient implementation. This currently consists of the initialization parameters which were specified in the GUI. Additional data may be accessible through JavaSamplerContext in the future.

      Get an iterator of the parameter names. Each entry in the Iterator is a String.
      Returns:
        an Iterator of Strings listing the names of the parameters which have been specified for this test.

    - #### getParameter

          public String getParameter(String name)

      Get the value of a specific parameter as a String, or null if the value was not specified.
      Parameters:
        `name` - the name of the parameter whose value should be retrieved
      Returns:
        the value of the parameter, or null if the value was not specified

    - #### getParameter

                                     String defaultValue)

      Get the value of a specified parameter as a String, or return the specified default value if the value was not specified.
      Parameters:
        `name` - the name of the parameter whose value should be retrieved
        `defaultValue` - the default value to return if the value of this parameter was not specified
      Returns:
        the value of the parameter, or the default value if the parameter was not specified

    - #### getIntParameter

          public int getIntParameter(String name)
                              throws NumberFormatException
