Constructor Detail

JavaSamplerContext

public JavaSamplerContext(Arguments args)
Create a new JavaSampler with the specified initialization parameters.

Parameters:
args - the initialization parameters.
Method Detail

containsParameter

public boolean containsParameter(String name)
Determine whether or not a value has been specified for the parameter with this name.

Parameters:
name - the name of the parameter to test
Returns:
true if the parameter value has been specified, false otherwise.

getParameterNamesIterator

public Iterator<String> getParameterNamesIterator()
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

public String getParameter(String name,
                           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
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().

Parameters:
name - the name of the parameter whose value should be retrieved

getIntParameter

public int getIntParameter(String name,
                           int 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().

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
