示例1: disposeStrike

import sun.java2d.Disposer; //导入方法依赖的package包/类
static void disposeStrike(final FontStrikeDisposer disposer) {
    // we need to execute the strike disposal on the rendering thread
    // because they may be accessed on that thread at the time of the
    // disposal (for example, when the accel. cache is invalidated)

    // Whilst this is a bit heavyweight, in most applications
    // strike disposal is a relatively infrequent operation, so it
    // doesn't matter. But in some tests that use vast numbers
    // of strikes, the switching back and forth is measurable.
    // So the "pollRemove" call is added to batch up the work.
    // If we are polling we know we've already been called back
    // and can directly dispose the record.
    // Also worrisome is the necessity of getting a GC here.

    if (Disposer.pollingQueue) {
        doDispose(disposer);
        return;
    }

    RenderQueue rq = null;
