从接口复制的说明: HttpData

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

参数:

buffer - must be not null

抛出:

java.io.IOException

setContent

public void setContent(java.io.InputStream inputStream)
                throws java.io.IOException

从接口复制的说明: HttpData

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

参数:

inputStream - must be not null

抛出:

java.io.IOException

addContent

public void addContent(ChannelBuffer buffer,
              boolean last)
                throws java.io.IOException

从接口复制的说明: HttpData

Add the content from the ChannelBuffer

参数:

last - True of the buffer is the last one

抛出:

java.io.IOException

setContent

public void setContent(java.io.File file)
                throws java.io.IOException

从接口复制的说明: HttpData

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

参数:

file - must be not null

抛出:

delete

public void delete()

从接口复制的说明: HttpData

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

get

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

参数:

encoding - the charset to use

返回:

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

getChannelBuffer

public ChannelBuffer getChannelBuffer()

Utility to go from a In Memory FileUpload to a Disk (or another implementation) FileUpload

返回:

the attached ChannelBuffer containing the actual bytes

getChunk

public ChannelBuffer getChunk(int length)
                       throws java.io.IOException

从接口复制的说明: HttpData

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.

返回:

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

抛出:

java.io.IOException

isInMemory

public boolean isInMemory()

从接口复制的说明: HttpData

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

返回:

True if the file contents is in memory.

renameTo

public boolean renameTo(java.io.File dest)
                 throws java.io.IOException

从接口复制的说明: HttpData

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

参数:

dest - destination file - must be not null

返回:

True if the write is successful

抛出:

java.io.IOException

getFile

public java.io.File getFile()
