org.springframework.cloud.function.compiler.java.MemoryBasedJavaFileManager

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, JavaFileManager, OptionChecker

public class MemoryBasedJavaFileManager
extends Object
implements JavaFileManager

A file manager that serves source code from in memory and ensures output results are kept in memory rather than being flushed out to disk. The JavaFileManager is also used as a lookup mechanism for resolving types.
