public JavaSamplerContext(Arguments args) 
{
        this.params = args.getArgumentsAsMap();
}

Create a new JavaSampler with the specified initialization parameters.

Parameters:

args - the initialization parameters.

 public boolean containsParameter(String name) 
{
        return params.containsKey(name);
}

Determine whether or not a value has been specified for the parameter with this name.

 public int getIntParameter(String name) throws NumberFormatException 
{
        if (params == null || !params.containsKey(name)) {
            throw new NumberFormatException("No value for parameter named '" + name + "'.");
        }
        return Integer.decode((String) params.get(name)).intValue();
}

Get the value of a specified parameter as an integer. An exception will be thrown if the parameter is not specified or if it is not an integer. The value may be specified in decimal, hexadecimal, or octal, as defined by Integer.decode().

 public int getIntParameter(String name,
    int defaultValue) 
{
        if (params == null || !params.containsKey(name)) {
            return defaultValue;
        }
        try {
            return Integer.decode((String) params.get(name)).intValue();
        } catch (NumberFormatException e) {
            log.warn("Value for parameter '" + name + "' not an integer: '" + params.get(name) + "'.  Using default: '"
                    + defaultValue + "'.", e);
            return defaultValue;
        }
}

Get the value of a specified parameter as an integer, or return the specified default value if the value was not specified or is not an integer. A warning will be logged if the value is not an integer. The value may be specified in decimal, hexadecimal, or octal, as defined by Integer.decode().

 public long getLongParameter(String name) throws NumberFormatException 
{
        if (params == null || !params.containsKey(name)) {
            throw new NumberFormatException("No value for parameter named '" + name + "'.");
        }
        return Long.decode((String) params.get(name)).longValue();
}

Get the value of a specified parameter as a long. An exception will be thrown if the parameter is not specified or if it is not a long. The value may be specified in decimal, hexadecimal, or octal, as defined by Long.decode().

 public long getLongParameter(String name,
    long defaultValue) 
{
        if (params == null || !params.containsKey(name)) {
            return defaultValue;
        }
        try {
            return Long.decode((String) params.get(name)).longValue();
        } catch (NumberFormatException e) {
            log.warn("Value for parameter '" + name + "' not a long: '" + params.get(name) + "'.  Using default: '"
                    + defaultValue + "'.", e);
            return defaultValue;
        }
}

Get the value of a specified parameter as along, or return the specified default value if the value was not specified or is not a long. A warning will be logged if the value is not a long. The value may be specified in decimal, hexadecimal, or octal, as defined by Long.decode().

 public String getParameter(String name) 
{
        return getParameter(name, null);
}

Get the value of a specific parameter as a String, or null if the value was not specified.

 public String getParameter(String name,
    String defaultValue) 
{
        if (params == null || !params.containsKey(name)) {
            return defaultValue;
        }
        return (String) params.get(name);
}

Get the value of a specified parameter as a String, or return the specified default value if the value was not specified.

 public Iterator getParameterNamesIterator() 
{
        return params.keySet().iterator();
}

Get an iterator of the parameter names. Each entry in the Iterator is a String.
