Method Detail

setContent

void setContent(io.netty.buffer.ByteBuf buffer)
                throws IOException

Set the content from the ChannelBuffer (erase any previous data)

Parameters:

buffer - must be not null

Throws:

IOException

addContent

void addContent(io.netty.buffer.ByteBuf buffer,
              boolean last)
                throws IOException

Add the content from the ChannelBuffer

Parameters:

buffer - must be not null except if last is set to False

last - True of the buffer is the last one

Throws:

IOException

setContent

void setContent(File file)
                throws IOException

Set the content from the file (erase any previous data)

Parameters:

file - must be not null

Throws:

IOException

setContent

void setContent(InputStream inputStream)
                throws IOException

Set the content from the inputStream (erase any previous data)

Parameters:

inputStream - must be not null

Throws:

IOException

isCompleted

boolean isCompleted()

Returns:

True if the InterfaceHttpData is completed (all data are stored)

length

long length()

Returns the size in byte of the InterfaceHttpData

Returns:

the size of the InterfaceHttpData

delete

void delete()

Deletes the underlying storage for a file item, including deleting any associated temporary disk file.

get

byte[] get()
           throws IOException

Returns the contents of the file item as an array of bytes.

Returns:

the contents of the file item as an array of bytes.

Throws:

IOException

getByteBuf

io.netty.buffer.ByteBuf getByteBuf()
                                   throws IOException

Returns the content of the file item as a ByteBuf

Returns:

the content of the file item as a ByteBuf

Throws:

IOException

getChunk

io.netty.buffer.ByteBuf getChunk(int length)
                                 throws IOException

Returns a ChannelBuffer for the content from the current position with at most length read bytes, increasing the current position of the Bytes read. Once it arrives at the end, it returns an EMPTY_BUFFER and it resets the current position to 0.

Returns:

a ChannelBuffer for the content from the current position or an EMPTY_BUFFER if there is no more data to return

Throws:

IOException

getString

String getString()
                 throws IOException

Returns the contents of the file item as a String, using the default character encoding.

Returns:

the contents of the file item as a String, using the default character encoding.

Throws:

IOException

getString

String getString(Charset encoding)
                 throws IOException

Returns the contents of the file item as a String, using the specified charset.

Parameters:

encoding - the charset to use

Returns:

the contents of the file item as a String, using the specified charset.

Throws:

IOException

setCharset

void setCharset(Charset charset)

Set the Charset passed by the browser if defined

Parameters:

charset - Charset to set - must be not null

getCharset

Charset getCharset()

Returns the Charset passed by the browser or null if not defined.

Returns:

the Charset passed by the browser or null if not defined.

renameTo

boolean renameTo(File dest)
                 throws IOException

A convenience getMethod to write an uploaded item to disk. If a previous one exists, it will be deleted. Once this getMethod is called, if successful, the new file will be out of the cleaner of the factory that creates the original InterfaceHttpData object.

Parameters:

dest - destination file - must be not null

Returns:

True if the write is successful

Throws:

IOException

isInMemory

boolean isInMemory()

Provides a hint as to whether or not the file contents will be read from memory.

Returns:

True if the file contents is in memory.

getFile

File getFile()
             throws IOException

Returns:

the associated File if this data is represented in a file

Throws:

IOException - if this data is not represented by a file
