Reusing a file manager can potentially reduce overhead of sharing between multiple compilation tasks.basic building block for customizing how a compiler reads.The standard file manager serves two purposes: The StandardJavaFileManager interfaceĭefines additional methods for creating file objects from Standard file manager for operating on regular files. Which are designed to ease the implementation of the SPI toĮvery compiler which implements this interface provides a There are a number of classes and interfaces in this package Implemented and used to provide customized services for aĬompiler and thus defines an SPI for compilers. Instead these interfaces are intended to be JavaFileObject are not intended to be used inĪpplications. Tools in general) the interfaces DiagnosticListener, Interfaces in this package defines an API for compilers (and The compiler relies on two services: diagnostic listener and file manager. Or higher must also support annotation processing. Specifications are defined in the Tool interface.Īdditionally, an instance of this interface supporting SourceVersion.RELEASE_6 Standard file manager such as the one returned by getStandardFileManager.Īn instance implementing this interface must conform to If no file manager is provided, the compiler tool will use a Standard file manager can be obtained by calling getStandardFileManager.Ī compiler tool must function with any file manager as long asĪny additional requirements as detailed in the methods below are Is the file manager that is native to the tool (or built-in). Listener is supplied, some diagnostics might not fit in aĭiagnostic and will be written to the default output.Ī compiler tool has an associated standard file manager, which Is provided, the diagnostics will be formatted in an unspecifiedįormat and written to the default output, which is The diagnostics will be supplied to the listener. The compiler might generate diagnostics during compilation (forĮxample, error messages). Interface to invoke Java programming language compilers from
