What is the “Execute Around” idiom?

public interface InputStreamAction
{
    void useStream(InputStream stream) throws IOException;
}

// Somewhere else

public void executeWithFile(String filename, InputStreamAction action)
    throws IOException
{
    InputStream stream = new FileInputStream(filename);
    try {
        action.useStream(stream);
    } finally {
        stream.close();
    }
}

// Calling it
executeWithFile("filename.txt", new InputStreamAction()
{
    public void useStream(InputStream stream) throws IOException
    {
        // Code to use the stream goes here
    }
});

//... chunk of init/preparation code ...
task A
//... chunk of cleanup/finishing code ...

//... chunk of identical init/preparation code ...
task B
//... chunk of identical cleanup/finishing code ...

//... chunk of identical init/preparation code ...
task C
//... chunk of identical cleanup/finishing code ...

//... and so on.

//pseudo-code:
class DoTask()
{
    do(task T)
    {
        // .. chunk of prep code
        // execute task T
        // .. chunk of cleanup code
    }
};

DoTask.do(task A)
DoTask.do(task B)
DoTask.do(task C)

//-- the target class
class Resource {
    def open () { // sensitive operation }
    def close () { // sensitive operation }
    //-- target method
    def doWork() { println "working";} }

//-- the execute around code
def static use (closure) {
    def res = new Resource();
    try {
        res.open();
        closure(res)
    } finally {
        res.close();
    }
}

//-- using the code
Resource.use { res -> res.doWork(); }
