I was reading the Java API Document in Eclipse for

int java.io.FileInputStream.read(byte[] b) throws IOException

and found the following explanation:

"Reads up to b.length bytes of data from this input stream into an array of bytes. This method blocks until some input is available."

What does block actually mean here? From my English knowledge, block is a transitive verb, which means it has to have an object following it... But here, it works like a intransitive verb....
