com.google.api.client.http
Class MultipartRelatedContent

java.lang.Object
  com.google.api.client.http.AbstractHttpContent
      com.google.api.client.http.MultipartRelatedContent

All Implemented Interfaces:

HttpContent

public final class MultipartRelatedContent
extends AbstractHttpContent

Serializes MIME Multipart/Related content as specified by RFC 2387: The MIME Multipart/Related Content-type.

Limitations:

• No support of parameters other than "boundary"
• No support for specifying headers for each content part
• The content type of each part is required, so HttpContent.getType() must not be null

Use forRequest(HttpRequest) to construct. For example:

  static void setMediaWithMetadataContent(
      HttpRequest request, AtomContent atomContent, InputStreamContent imageContent) {
    MultipartRelatedContent.forRequest(request, atomContent, imageContent);
  }
 

Implementation is not thread-safe.

Since:

1.1

Constructor Detail

MultipartRelatedContent

public MultipartRelatedContent(HttpContent firstPart,
                               HttpContent... otherParts)

Parameters:

firstPart - first HTTP content part

otherParts - other HTTP content parts

Since:

1.5

Method Detail

forRequest

public void forRequest(HttpRequest request)

Sets this multi-part content as the content for the given HTTP request, and set the MIME version header to "1.0".

Parameters:

request - HTTP request

Since:

1.5

writeTo

public void writeTo(OutputStream out)
             throws IOException

Description copied from interface: HttpContent

Writes the content to the given output stream.

Throws:

IOException

computeLength

public long computeLength()
                   throws IOException

Description copied from class: AbstractHttpContent

Computes and returns the content length or less than zero if not known.

Subclasses may override, but by default this computes the length by calling HttpContent.writeTo(OutputStream) with an output stream that does not process the bytes written, but only retains the count of bytes. If AbstractHttpContent.retrySupported() is false, it will instead return -1.

Overrides:

computeLength in class AbstractHttpContent

Throws:

IOException

getType

public String getType()

Description copied from interface: HttpContent

Returns the content type or null for none.

retrySupported

public boolean retrySupported()

Description copied from class: AbstractHttpContent

Default implementation returns true, but subclasses may override.

Specified by:

retrySupported in interface HttpContent

Overrides:

retrySupported in class AbstractHttpContent

getBoundary

public String getBoundary()

Returns the boundary string to use.

Since:

1.5

setBoundary

public MultipartRelatedContent setBoundary(String boundary)

Sets the boundary string to use.

Defaults to "END_OF_PART".

Since:

1.5

getParts

public Collection<HttpContent> getParts()

Returns the HTTP content parts.

Since:

1.5
