getContentType

public String getContentType()

从接口 Part 复制的描述

Gets the content type of this part.

指定者：

接口 Part 中的 getContentType

返回：

The content type of this part.

另请参见：

Part.getContentType()

getHeader

public String getHeader(String name)

从接口 Part 复制的描述

Returns the value of the specified mime header as a String. If the Part did not include a header of the specified name, this method returns null. If there are multiple headers with the same name, this method returns the first header in the part. The header name is case insensitive. You can use this method with any request header.

指定者：

接口 Part 中的 getHeader

参数：

name - a String specifying the header name

返回：

a String containing the value of the requested header, or null if the part does not have a header of that name

另请参见：

Part.getHeader(java.lang.String)

getHeaderNames

public Collection<String> getHeaderNames()

从接口 Part 复制的描述

Gets the header names of this Part.

Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null

Any changes to the returned Collection must not affect this Part.

指定者：

接口 Part 中的 getHeaderNames

返回：

a (possibly empty) Collection of the header names of this Part

另请参见：

Part.getHeaderNames()

getHeaders

public Collection<String> getHeaders(String name)

从接口 Part 复制的描述

Gets the values of the Part header with the given name.

Any changes to the returned Collection must not affect this Part.

Part header names are case insensitive.

指定者：

接口 Part 中的 getHeaders

参数：

name - the header name whose values to return

返回：

a (possibly empty) Collection of the values of the header with the given name

另请参见：

Part.getHeaders(java.lang.String)

getInputStream

public InputStream getInputStream()
                           throws IOException

从接口 Part 复制的描述

Gets the content of this part as an InputStream

指定者：

接口 Part 中的 getInputStream

返回：

The content of this part as an InputStream

抛出：

IOException - If an error occurs in retrieving the contet as an InputStream

另请参见：

Part.getInputStream()

getBytes

public byte[] getBytes()

getName

public String getName()

从接口 Part 复制的描述

Gets the name of this part

指定者：

接口 Part 中的 getName

返回：

The name of this part as a String

另请参见：

Part.getName()

getSize

public long getSize()

从接口 Part 复制的描述

Returns the size of this fille.

指定者：

接口 Part 中的 getSize

返回：

a long specifying the size of this part, in bytes.

另请参见：

Part.getSize()

write

public void write(String fileName)
           throws IOException

从接口 Part 复制的描述

A convenience method to write this uploaded item to disk.

This method is not guaranteed to succeed if called more than once for the same part. 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：

接口 Part 中的 write

参数：

fileName - the name of the file to which the stream will be written. The file is created relative to the location as specified in the MultipartConfig

抛出：

IOException - if an error occurs.

另请参见：

Part.write(java.lang.String)

delete

public void delete()
            throws IOException

Remove the file, whether or not Part.write() was called on it (ie no longer temporary)

指定者：

接口 Part 中的 delete

抛出：

IOException - if an error occurs.

另请参见：

Part.delete()

cleanUp

public void cleanUp()
             throws IOException

Only remove tmp files.

抛出：

IOException

getFile

public File getFile()

Get the file, if any, the data has been written to.

返回：

getContentDispositionFilename

public String getContentDispositionFilename()

Get the filename from the content-disposition.

返回：

null or the filename
