Method Detail
-
doDetach
protected void doDetach() throws java.lang.Exception
Detaches this file object from its file resource.- Overrides:
doDetach
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doGetType
protected FileType doGetType() throws java.lang.Exception
Determines the type of this file. Must not return null. The return value of this method is cached, so the implementation can be expensive.- Specified by:
doGetType
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doListChildren
protected java.lang.String[] doListChildren() throws java.lang.Exception
Lists the children of this file.- Specified by:
doListChildren
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doGetContentSize
protected long doGetContentSize() throws java.lang.Exception
Returns the size of the file content (in bytes).- Specified by:
doGetContentSize
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doGetLastModifiedTime
protected long doGetLastModifiedTime() throws java.lang.Exception
Returns the last modified time of this file. This implementation throws an exception.- Overrides:
doGetLastModifiedTime
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doGetInputStream
protected java.io.InputStream doGetInputStream() throws java.lang.Exception
Creates an input stream to read the file content from. Is only called ifdoGetType()
returnsFileType.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.
- Specified by:
doGetInputStream
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doGetRandomAccessContent
protected RandomAccessContent doGetRandomAccessContent(RandomAccessMode mode) throws java.lang.Exception
Description copied from class:AbstractFileObject
Creates access to the file for random i/o. Is only called ifAbstractFileObject.doGetType()
returnsFileType.FILE
.It is guaranteed that there are no open output streams for this file when this method is called.
- Overrides:
doGetRandomAccessContent
in classAbstractFileObject
- Throws:
java.lang.Exception
-
encodePath
protected java.lang.String encodePath(java.lang.String decodedPath) throws org.apache.commons.httpclient.URIException
- Throws:
org.apache.commons.httpclient.URIException
-
getFileContentInfoFactory
protected FileContentInfoFactory getFileContentInfoFactory()
Description copied from class:AbstractFileObject
create the filecontentinfo implementation- Overrides:
getFileContentInfoFactory
in classAbstractFileObject
