setContent

public void setContent(ByteBuf buffer)
                throws java.io.IOException

从接口复制的说明: HttpData

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

ReferenceCounted.release() ownership of buffer is transferred to this HttpData.

参数:

buffer - must be not null

抛出:

java.io.IOException

addContent

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

从接口复制的说明: HttpData

Add the content from the ChannelBuffer

ReferenceCounted.release() ownership of buffer is transferred to this HttpData.

参数:

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

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:

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

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

public byte[] get()
           throws java.io.IOException

从接口复制的说明: HttpData

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.

返回:

抛出:

java.io.IOException

getByteBuf

public ByteBuf getByteBuf()
                   throws java.io.IOException
