Method Detail

parseRequest

private void parseRequest(HttpServletRequest request)

extractFilename

private java.lang.String extractFilename(java.lang.String contentDisposition)

initializeMultipart

protected void initializeMultipart()

Description copied from class: AbstractMultipartHttpServletRequest

Lazily initialize the multipart request, if possible. Only called if not already eagerly initialized.

Overrides:

initializeMultipart in class AbstractMultipartHttpServletRequest

getParameterNames

public java.util.Enumeration<java.lang.String> getParameterNames()

getParameterMap

public java.util.Map<java.lang.String,java.lang.String[]> getParameterMap()

getMultipartContentType

public java.lang.String getMultipartContentType(java.lang.String paramOrFileName)

Description copied from interface: MultipartRequest

Determine the content type of the specified request part.

Parameters:

paramOrFileName - the name of the part

Returns:

the associated content type, or null if not defined

getMultipartHeaders

public HttpHeaders getMultipartHeaders(java.lang.String paramOrFileName)

Description copied from interface: MultipartHttpServletRequest

Return the headers associated with the specified part of the multipart request.

If the underlying implementation supports access to headers, then all headers are returned. Otherwise, the returned headers will include a 'Content-Type' header at the very least.
