Field Detail
entry
protected ZipEntry entry(Code)




Constructor Detail
ZipFileObject
protected ZipFileObject(FileName name, ZipEntry entry, ZipFileSystem fs, boolean zipExists) throws FileSystemException(Code)




Method Detail
attachChild
public void attachChild(FileName childName)(Code)
Attaches a child



doGetContentSize
protected long doGetContentSize()(Code)
Returns the size of the file content (in bytes). Is only called if ZipFileObject.doGetType returns FileType.FILE .



doGetInputStream
protected InputStream doGetInputStream() throws Exception(Code)
Creates an input stream to read the file content from. Is only called if ZipFileObject.doGetType returns FileType.FILE . The input stream returned by this method is guaranteed to be closed before this method is called again.



doGetLastModifiedTime
protected long doGetLastModifiedTime() throws Exception(Code)
Returns the last modified time of this file.



doGetType
protected FileType doGetType()(Code)
Returns the file's type.



doListChildren
protected String[] doListChildren()(Code)
Lists the children of the file.



isWriteable
public boolean isWriteable() throws FileSystemException(Code)
Determines if this file can be written to. true if this file is writeable, false if not.



setZipEntry
protected void setZipEntry(ZipEntry entry)(Code)
Sets the details for this file object.
