public abstract static class MultiPart.Part extends Object implements Content.Source.Factory, Closeable

A single part of a multipart content.

A part has an optional name, an optional fileName, optional headers and an optional content.

  • Constructor Details

  • Method Details

    • getName

      public String getName()

      Returns the name of this part, as specified by the HttpHeader.CONTENT_DISPOSITION's name parameter.

      While the name parameter is mandatory per RFC 7578, older HTTP clients may not send it.

      Returns:
      the name of this part, or null if there is no name

    • getFileName

      public String getFileName()

      Returns the file name of this part, as specified by the HttpHeader.CONTENT_DISPOSITION's filename parameter.

      While the filename parameter is mandatory per RFC 7578 when uploading files, older HTTP clients may not send it.

      The file name may be absent if the part is not a file upload.

      Returns:
      the file name of this part, or null if there is no file name

    • getContentSource

      public Content.Source getContentSource()

      Returns the content of this part as a Content.Source.

      Calling this method multiple times will return the same instance, which can only be consumed once.

      The content type and content encoding are specified in this part's headers.

      The content encoding may be specified by the part named _charset_, as specified in RFC 7578, section 4.6.

      Returns:
      the content of this part
      See Also:

    • newContentSource

      @Deprecated(since="12.0.20", forRemoval=true) public Content.Source newContentSource()
      Deprecated, for removal: This API element is subject to removal in a future version.
      override newContentSource(ByteBufferPool.Sized, long, long) instead.

      Returns the content of this part as a new Content.Source

      If the content is reproducible, invoking this method multiple times will return a different independent instance for every invocation.

      If the content is not reproducible, subsequent calls to this method will return null.

      The content type and content encoding are specified in this part's headers.

      The content encoding may be specified by the part named _charset_, as specified in RFC 7578, section 4.6.

      Returns:
      the content of this part as a new Content.Source or null if the content cannot be consumed multiple times.

    • newContentSource

      public Content.Source newContentSource(ByteBufferPool.Sized bufferPool, long first, long length)
      Creates a new Content.Source.

      Returns the content of this part as a new Content.Source

      If the content is reproducible, invoking this method multiple times will return a different independent instance for every invocation.

      If the content is not reproducible, subsequent calls to this method will return null.

      The content type and content encoding are specified in this part's headers.

      The content encoding may be specified by the part named _charset_, as specified in RFC 7578, section 4.6.

      Specified by:
      newContentSource in interface Content.Source.Factory
      Parameters:
      bufferPool - the ByteBufferPool.Sized to get buffers from. null means allocate new buffers as needed.
      first - the first byte of the resource to start from.
      length - the length of the content to make available, -1 for the full length.
      Returns:
      a Content.Source.

    • getLength

      public long getLength()

    • getContentAsString

      public String getContentAsString(Charset defaultCharset)

      Returns the content of this part as a string.

      The charset used to decode the bytes is:

      • the charset parameter of the HttpHeader.CONTENT_TYPE header, if non-null;
      • otherwise, the given defaultCharset parameter, if non-null;
      • otherwise, UTF-8.
      Parameters:
      defaultCharset - the charset to use to decode the bytes, if the charset parameter of the Content-Type header is missing
      Returns:
      the content of this part as a string
