Examples with Sampler org.apache.jmeter.samplers.Sampler used on opensource projects

Example 1 with Sampler

use of org.apache.jmeter.samplers.Sampler in project jmeter by apache.

the class GenericController method nextIsAController.

/**
     * Called by {@link #next()} if the element is a Controller, and returns the
     * next sampler from the controller. If this is <code>null</code>, then
     * updates the current pointer and makes recursive call to {@link #next()}.
     * 
     * @param controller the current <em>next</em> element
     * @return the next sampler
     * @throws NextIsNullException when the end of the list has already been reached

Example 2 with Sampler

use of org.apache.jmeter.samplers.Sampler in project jmeter by apache.

the class GenericController method next.

/**

     * <p>
     * Gets the list element using current pointer.
     * If this is <code>null</code>, calls {@link #nextIsNull()}.

     *
     * <p>
     * If the list element is a {@link Sampler}, calls {@link #nextIsASampler(Sampler)},
     * otherwise calls {@link #nextIsAController(Controller)}
     * </p>
     *
     * <p>
     * If any of the called methods throws {@link NextIsNullException}, returns <code>null</code>,
     * otherwise the value obtained above is returned.
