Constructor Detail BenchBase protected BenchBase(String config)(Code) Constructor. Parameters:   config - test configuration name Method Detail getName public String getName()(Code) Get configuration name. Returns the name of the document model used by this test, with any supplied variant information appended in parenthesis. document model name initMemory protected void initMemory()(Code) Initializes the memory state prior to a test run. This method first requests a garbage collection operation, then waits for a fixed interval in order to encourage the JVM to do the collection. It also sets the start of test value for memory usage. initTime protected void initTime()(Code) Initializes the time prior to a test run. This method justs sets the start of test time from the system clock. printSummary protected void printSummary(String lead, DocumentSummary info, PrintStream print)(Code) Print document summary information. Prints the information with a supplied lead phrase. Parameters:   lead - lead text phrase for document summary Parameters:   info - document summary information Parameters:   print - stream on which to print reportSpace protected int reportSpace(String test)(Code) Report the results of a memory test run. First attempts a garbage collection operation before computing the difference between the memory in use at the end of the test and that in use at the start of the test. Prints the space used by the test and sets the current space as the base for the next test. Parameters:   test - test description for display space used by test reportTime protected int reportTime(String test)(Code) Report the results of a time test run. Prints the time taken for the last test and sets the current time as the start time for the next test. Parameters:   test - test description for display milliseconds taken for the test reportValue protected void reportValue(String lead, int value)(Code) Report a value. Prints the leading text and the value with a space between, if printing is enabled. Parameters:   lead - leading text for test results Parameters:   value - value to be printed runSpaceTest abstract public int[] runSpaceTest(int passes, int excludes, byte[][] texts)(Code) Main space test method. This must be implemented by the subclass to perform the sequence of space tests appropriate to the test platform. Parameters:   passes - number of passes of each test Parameters:   excludes - number of initialization passes excluded from averages Parameters:   texts - document texts for test result spaces array runTimeTest abstract public int[] runTimeTest(int passes, int excludes, byte[][] texts)(Code) Main time test method. This must be implemented by the subclass to perform the sequence of speed tests appropriate to the test platform. Parameters:   passes - number of passes of each test Parameters:   excludes - number of initialization passes excluded from averages Parameters:   texts - document texts for test result times array setPrint public void setPrint(PrintStream print)(Code) Set output print stream for printing detailed test run results. Parameters:   print - test results listing destination (null ifno listing output) setShowDocument public void setShowDocument(boolean show)(Code) Set flag for printing document summary information. Parameters:   show - flag for document summary information to be printed setShowPass public void setShowPass(boolean show)(Code) Set flag for printing individual test pass results. Parameters:   show - flag for document summary information to be printed setVariant protected void setVariant(String variant)(Code) Set configuration variant information. This may be used by subclasses which need to deal with several variations of a single configuration. Parameters:   variant - configuration variant description, appended to name testPassSpace protected int testPassSpace()(Code) Find test pass space. Besides returning the space for the last test pass, this sets the current space usage as the start of the next test pass. bytes of memory added by test pass (negative if space released) testPassTime protected int testPassTime()(Code) Find test pass time. Besides returning the time for the last test pass, this sets the current time as the start of the next test pass. milliseconds taken for the test Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
