name - The name of the file.fs - The FileSystem.protected FileType doGetType() throws Exception
AbstractFileObjectdoGetType in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected String[] doListChildren() throws Exception
AbstractFileObjectAbstractFileObject.doGetType()
returns FileType.FOLDER. The return value of this method
is cached, so the implementation can be expensive.doListChildren in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected long doGetContentSize()
throws Exception
AbstractFileObjectAbstractFileObject.doGetType() returns FileType.FILE.doGetContentSize in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected InputStream doGetInputStream() throws Exception
AbstractFileObjectAbstractFileObject.doGetType() returns FileType.FILE.
It is guaranteed that there are no open output streams for this file when this method is called.
The returned stream does not have to be buffered.
doGetInputStream in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected OutputStream doGetOutputStream(boolean bAppend) throws Exception
AbstractFileObjectAbstractFileObject.doIsWriteable() returns true.
AbstractFileObject.doGetType() returns FileType.FILE, or
AbstractFileObject.doGetType() returns FileType.IMAGINARY, and the file's
parent exists and is a folder.
The returned stream does not have to be buffered.
This implementation throws an exception.
doGetOutputStream in class AbstractFileObject<RamFileSystem>bAppend - true if the file should be appended to, false if it should be overwritten.Exception - if an error occurs.protected void doDelete()
throws Exception
AbstractFileObjectAbstractFileObject.doGetType() does not return FileType.IMAGINARY.AbstractFileObject.doIsWriteable() returns true.doDelete in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected long doGetLastModifiedTime()
throws Exception
AbstractFileObjectAbstractFileObject.doGetType() does not return FileType.IMAGINARY.
This implementation throws an exception.
doGetLastModifiedTime in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected boolean doSetLastModifiedTime(long modtime)
throws Exception
AbstractFileObject
Is only called if AbstractFileObject.doGetType() does not return FileType.IMAGINARY.
This implementation throws an exception.
doSetLastModifiedTime in class AbstractFileObject<RamFileSystem>modtime - The last modification time.Exception - Any Exception thrown is wrapped in FileSystemException.protected void doCreateFolder()
throws Exception
AbstractFileObjectAbstractFileObject.doGetType() returns FileType.IMAGINARY.doCreateFolder in class AbstractFileObject<RamFileSystem>Exception - if an error occurs.protected void doRename(FileObject newFile) throws Exception
AbstractFileObjectIs only called when:
AbstractFileObject.doIsWriteable() returns true.This implementation throws an exception.
doRename in class AbstractFileObject<RamFileSystem>newFile - A FileObject with the new file name.Exception - if an error occurs.protected RandomAccessContent doGetRandomAccessContent(RandomAccessMode mode) throws Exception
AbstractFileObjectAbstractFileObject.doGetType() returns FileType.FILE.
It is guaranteed that there are no open output streams for this file when this method is called.
doGetRandomAccessContent in class AbstractFileObject<RamFileSystem>mode - The mode to access the file.Exception - if an error occurs.protected void doAttach()
throws Exception
AbstractFileObjectThis method is called before any of the doBlah() or onBlah() methods. Sub-classes can use this method to perform lazy initialisation.
This implementation does nothing.
