addContent, checkSize, definedLength, delete, get, getByteBuf, getCharset, getChunk, getFile, getMaxSize, getString, getString, isCompleted, isInMemory, length, renameTo, setCharset, setContent, setContent, setContent, setMaxSize

Modifier and Type	Method	Description
void	addContent(ByteBuf buffer, boolean last)	Add the content from the ChannelBuffer
void	checkSize(long newSize)	Check if the new size is not reaching the max limit allowed.
long	definedLength()	Returns the defined length of the HttpData.
void	delete()	Deletes the underlying storage for a file item, including deleting any associated temporary disk file.
byte[]	get()	Returns the contents of the file item as an array of bytes. Note: this method will allocate a lot of memory, if the data is currently stored on the file system.
ByteBuf	getByteBuf()	Returns the content of the file item as a ByteBuf. Note: this method will allocate a lot of memory, if the data is currently stored on the file system.
Charset	getCharset()	Returns the Charset passed by the browser or null if not defined.
ByteBuf	getChunk(int length)	Returns a ChannelBuffer for the content from the current position with at most length read bytes, increasing the current position of the Bytes read.
File	getFile()
long	getMaxSize()	Returns the maxSize for this HttpData.
String	getString()	Returns the contents of the file item as a String, using the default character encoding.
String	getString(Charset encoding)	Returns the contents of the file item as a String, using the specified charset.
boolean	isCompleted()
boolean	isInMemory()	Provides a hint as to whether or not the file contents will be read from memory.
long	length()	Returns the size in byte of the InterfaceHttpData
boolean	renameTo(File dest)	A convenience getMethod to write an uploaded item to disk.
void	setCharset(Charset charset)	Set the Charset passed by the browser if defined
void	setContent(ByteBuf buffer)	Set the content from the ChannelBuffer (erase any previous data)
void	setContent(File file)	Set the content from the file (erase any previous data)
void	setContent(InputStream inputStream)	Set the content from the inputStream (erase any previous data)
void	setMaxSize(long maxSize)	Set the maxSize for this HttpData.

Methods inherited from interface ReferenceCounted

refCnt, release, release

Modifier and Type	Method	Description
int	refCnt()	Returns the reference count of this object.
boolean	release()	Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.
boolean	release(int decrement)	Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.

copy

Attribute copy()

Description copied from interface: ByteBufHolder

Creates a deep copy of this ByteBufHolder.

Specified by:

copy in interface ByteBufHolder

Specified by:

copy in interface HttpData

duplicate

Attribute duplicate()

Description copied from interface: ByteBufHolder

Duplicates this ByteBufHolder. Be aware that this will not automatically call ByteBufHolder.retain().
