class:JavaFileManager [NONE]

    public interface JavaFileManager
    extends java.io.Closeable, java.io.Flushable, javax.tools.OptionChecker
    File manager for tools operating on Java™ programming language source and class files. In this context, file means an abstraction of regular files and other sources of data.

    When constructing new JavaFileObjects, the file manager must determine where to create them. For example, if a file manager manages regular files on a file system, it would most likely have a current/working directory to use as default location when creating or finding files. A number of hints can be provided to a file manager as to where to create files. Any file manager might choose to ignore these hints.

    Some methods in this interface use class names. Such class names must be given in the Java Virtual Machine internal form of fully qualified class and interface names. For convenience '.' and '/' are interchangeable. The internal form is defined in chapter four of The Java™ Virtual Machine Specification .

    Discussion: this means that the names "java/lang.package-info", "java/lang/package-info", "java.lang.package-info", are valid and equivalent. Compare to binary name as defined in The Java™ Language Specification , section 13.1 "The Form of a Binary".

    The case of names is significant. All names should be treated as case-sensitive. For example, some file systems have case-insensitive, case-aware file names. File objects representing such files should take care to preserve case by using File.getCanonicalFile() or similar means. If the system is not case-aware, file objects must use other means to preserve case.

    Relative names : some methods in this interface use relative names. A relative name is a non-null, non-empty sequence of path segments separated by '/'. '.' or '..' are invalid path segments. A valid relative name must match the "path-rootless" rule of RFC 3986, section 3.3. Informally, this should be true:

      URI.create(relativeName).normalize().getPath().equals(relativeName)

    All methods in this interface might throw a SecurityException.

    An object of this interface is not required to support multi-threaded access, that is, be synchronized. However, it must support concurrent access to different file objects created by this object.

    Implementation note: a consequence of this requirement is that a trivial implementation of output to a JarOutputStream is not a sufficient implementation. That is, rather than creating a JavaFileObject that returns the JarOutputStream directly, the contents must be cached until closed and then written to the JarOutputStream.

    Unless explicitly allowed, all methods in this interface might throw a NullPointerException if given a null argument.

    className - the name of a class
    kind - the kind of file, must be one of SOURCE or CLASS
    sibling - a file object to be used as hint for placement; might be null

method:getFileForInput(javax.tools.JavaFileManager.Location, java.lang.String, java.lang.String) [CHANGED]

  • getFileForInput

    javax.tools.FileObject getFileForInput(JavaFileManager.Location location,

                                    throws java.io.IOException
    Returns a file object for input representing the specified relative name in the specified package in the given package-oriented location.

    If the returned object represents a source or class file, it must be an instance of JavaFileObject.

    Informally, the file object returned by this method is located in the concatenation of the location, package name, and relative name. For example, to locate the properties file "resources/compiler.properties" in the package "com.sun.tools.javac" in the SOURCE_PATH location, this method might be called like so:

    getFileForInput(SOURCE_PATH, "com.sun.tools.javac", "resources/compiler.properties");

    If the call was executed on Windows, with SOURCE_PATH set to "C:\Documents and Settings\UncleBob\src\share\classes", a valid result would be a file object representing the file "C:\Documents and Settings\UncleBob\src\share\classes\com\sun\tools\javac\resources\compiler.properties".

    Parameters:
    location - a package-oriented location
    packageName - a package name
    relativeName - a relative name
    Returns:
    a file object, might return null if the file does not exist
    Throws:
    java.lang.IllegalArgumentException - if the location is not known to this file manager and the file manager does not support unknown locations, or if relativeName is not valid, or if the location is a module-oriented location
    java.io.IOException - if an I/O error occurred, or if close() has been called and this file manager cannot be reopened
    java.lang.IllegalStateException - if close() has been called and this file manager cannot be reopened

    If the returned object represents a source or class file, it must be an instance of JavaFileObject.

    Informally, the file object returned by this method is located in the concatenation of the location, package name, and relative name. For example, to locate the properties file "resources/compiler.properties" in the package "com.sun.tools.javac" in the SOURCE_PATH location, this method might be called like so:

    getFileForInput(SOURCE_PATH, "com.sun.tools.javac", "resources/compiler.properties");

    If the call was executed on Windows, with SOURCE_PATH set to "C:\Documents and Settings\UncleBob\src\share\classes", a valid result would be a file object representing the file "C:\Documents and Settings\UncleBob\src\share\classes\com\sun\tools\javac\resources\compiler.properties".

    Parameters:
    location - a location
    packageName - a package name
    relativeName - a relative name
    Returns:
    a file object, might return null if the file does not exist
    Throws:
    java.lang.IllegalArgumentException - if the location is not known to this file manager and the file manager does not support unknown locations, or if relativeName is not valid
    java.io.IOException - if an I/O error occurred, or if close() has been called and this file manager cannot be reopened
    java.lang.IllegalStateException - if close() has been called and this file manager cannot be reopened

    Returns a file object for output representing the specified relative name in the specified package in the given location.

    Optionally, this file manager might consider the sibling as a hint for where to place the output. The exact semantics of this hint is unspecified. The JDK compiler, javac, for example, will place class files in the same directories as originating source files unless a class file output directory is provided. To facilitate this behavior, javac might provide the originating source file as sibling when calling this method.

    If the returned object represents a source or class file, it must be an instance of JavaFileObject.

    Informally, the file object returned by this method is located in the concatenation of the location, package name, and relative name or next to the sibling argument. See getFileForInput for an example.

    Parameters:
    location - aan output location
    packageName - a package name

                      throws java.io.IOException
    
    Determines whether or not a given file object is "contained in" a specified location.

    For a package-oriented location, a file object is contained in the location if there exist values for packageName and relativeName such that either of the following calls would return the same file object:

         
    getFileForInput(location, packageName, relativeName)
         getFileForOutput(location, packageName, relativeName, null)
     
    

    For a module-oriented location, a file object is contained in the location if there exists a module that may be obtained by the call:

         
    getLocationForModule(location, moduleName)
     
    
    such that the file object is contained in the (package-oriented) location for that module.

    Implementation Requirements:
    This implementation throws UnsupportedOperationException.
    Parameters:
    location - the location
    fo - the file object
    Returns:
    whether or not the file is contained in the location
    Throws:
    java.io.IOException - if there is a problem determining the result
    java.lang.UnsupportedOperationException - if the method is not supported
