FileItemBase

public FileItemBase(FileItemStream stream)

方法详细资料

getHeaders

public FileItemHeaders getHeaders()

从接口复制的说明: FileItemStream

Returns the collection of headers defined locally within this item.

指定者:

getHeaders 在接口中 FileItemStream

返回:

the FileItemHeaders present for this item.

getContentType

public String getContentType()

从接口复制的说明: FileItemStream

Returns the content type passed by the browser or null if not defined.

指定者:

getContentType 在接口中 FileItemStream

返回:

The content type passed by the browser or null if not defined.

getName

public String getName()

从接口复制的说明: FileItemStream

Returns the original filename in the client's filesystem, as provided by the browser (or other client software). In most cases, this will be the base file name, without path information. However, some clients, such as the Opera browser, do include path information.

指定者:

getName 在接口中 FileItemStream

返回:

The original filename in the client's filesystem.

getFieldName

public String getFieldName()

从接口复制的说明: FileItemStream

Returns the name of the field in the multipart form corresponding to this file item.

指定者:

getFieldName 在接口中 FileItemStream

返回:

The name of the form field.

isFormField

public boolean isFormField()

从接口复制的说明: FileItemStream

Determines whether or not a FileItem instance represents a simple form field.

指定者:

isFormField 在接口中 FileItemStream

返回:

true if the instance represents a simple form field; false if it represents an uploaded file.

get

public byte[] get()
           throws IOException

从接口复制的说明: FileItem

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

指定者:

get 在接口中 FileItem

返回:

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

抛出:

IOException

getString

public String getString(String encoding)
                 throws IOException

从接口复制的说明: FileItem

Returns the contents of the file item as a String, using the specified encoding. This method uses FileItem.get() to retrieve the contents of the item.

指定者:

getString 在接口中 FileItem

参数:

encoding - The character encoding to use.

返回:

The contents of the item, as a string.

抛出:

UnsupportedEncodingException - if the requested character encoding is not available.

IOException

getString

public String getString()
                 throws IOException

从接口复制的说明: FileItem

Returns the contents of the file item as a String, using the default character encoding. This method uses FileItem.get() to retrieve the contents of the item.

指定者:

getString 在接口中 FileItem

返回:

The contents of the item, as a string.

抛出:

IOException

writeTo

public void writeTo(File outputFile)
             throws IOException

从接口复制的说明: FileItem

A convenience method to write an uploaded item to disk. The client code is not concerned with whether or not the item is stored in memory, or on disk in a temporary location. They just want to write the uploaded item to a file.

This method is not guaranteed to succeed if called more than once for the same item. This allows a particular implementation to use, for example, file renaming, where possible, rather than copying all of the underlying data, thus gaining a significant performance benefit.

指定者:

writeTo 在接口中 FileItem

参数:

outputFile - The File into which the uploaded item should be stored.

抛出:

IOException

writeTo

public void writeTo(OutputStream outStream)
             throws IOException
