Method Detail

saveDetails

public void saveDetails(URLConnection conn,
                        HTTPSampleResult res)
Save the Last-Modified, Etag, and Expires headers if the result is cacheable. Version for Java implementation.

Parameters:
conn - connection

                 throws org.apache.commons.httpclient.URIException
Save the Last-Modified, Etag, and Expires headers if the result is cacheable. Version for Commons HttpClient implementation.

Parameters:
method - HttpMethod to get header information from
res - result to decide if result is cacheable
Throws:
org.apache.commons.httpclient.URIException - if extraction of the the uri from method fails

                        HTTPSampleResult res)
Save the Last-Modified, Etag, and Expires headers if the result is cacheable. Version for Apache HttpClient implementation.

Parameters:
method - HttpResponse to extract header information from
res - result to decide if result is cacheable

setHeaders

public void setHeaders(URL url,
                       org.apache.commons.httpclient.HttpMethod method)
Check the cache, and if there is a match, set the headers: Commons HttpClient version

Parameters:
url - URL to look up in cache
method - where to set the headers

setHeaders

public void setHeaders(URL url,
                       org.apache.http.client.methods.HttpRequestBase request)
Check the cache, and if there is a match, set the headers: Apache HttpClient version.

Parameters:

request - where to set the headers

setHeaders

public void setHeaders(HttpURLConnection conn,
                       URL url)
Check the cache, and if there is a match, set the headers:

Parameters:

conn - where to set the headers

inCache

public boolean inCache(URL url)
Check the cache, if the entry has an expires header and the entry has not expired, return true

Parameters:
url - URL to look up in cache
Returns:
true if entry has an expires header and the entry has not expired, else false

getClearEachIteration

public boolean getClearEachIteration()

setClearEachIteration

public void setClearEachIteration(boolean clear)

getUseExpires

public boolean getUseExpires()

setUseExpires

public void setUseExpires(boolean expires)

getMaxSize

public int getMaxSize()
Returns:
int cache max size

setMaxSize

public void setMaxSize(int size)
Parameters:
size - int cache max size

clear

public void clear()
Description copied from class: AbstractTestElement
Clear the TestElement of all data.

Specified by:
clear in interface TestElement
Overrides:
clear in class AbstractTestElement

testStarted

public void testStarted()
Description copied from interface: TestStateListener

Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
testStarted in interface TestStateListener
See Also:
StandardJMeterEngine.run()

testEnded

public void testEnded()
Description copied from interface: TestStateListener

Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
testEnded in interface TestStateListener
See Also:
StandardJMeterEngine.stopTest()

testStarted

public void testStarted(String host)
Description copied from interface: TestStateListener

Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
testStarted in interface TestStateListener
Parameters:
host - name of host
See Also:
StandardJMeterEngine.run()

testEnded

public void testEnded(String host)
Description copied from interface: TestStateListener

Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:
testEnded in interface TestStateListener
Parameters:
host - name of host
See Also:
StandardJMeterEngine.stopTest()

testIterationStart

public void testIterationStart(LoopIterationEvent event)
Description copied from interface: TestIterationListener
Each time through a Thread Group's test script, an iteration event is fired for each thread. This will be after the test elements have been cloned, so in general the instance will not be the same as the ones the start/end methods call.

Specified by:
testIterationStart in interface TestIterationListener
Parameters:
event - the iteration event
