public class FormDataMultiPart
extends MultiPart

Subclass of MultiPart with specialized support for media type multipart/form-data. See RFC 2388 for the formal definition of this media type.

For a server side application wishing to process an incoming multipart/form-data message, the following features are provided:

• Incoming entities will be of type FormDataMultiPart, enabling access to the specialized methods.
• Incoming body parts will be of type FormDataBodyPart, enabling access to its specialized methods.
• Convenience method to return the FormDataBodyPart for a specified control name.
• Convenience method to return a Map of FormDataBodyParts for all fields, keyed by field name.

For a client side application wishing to construct an outgoing multipart/form-data message, the following features are provided:

• Media type of the FormDataMultiPart instance will automatically set to multipart/form-data.
• Builder pattern method to add simple field values as body parts of type text/plain.
• Builder pattern method to add named "file" field values with arbitrary media types.

FIXME - Consider supporting the use case of a nested multipart/mixed body part to contain multiple uploaded files.

this instance.

field

public FormDataMultiPart field(java.lang.String name,
                               java.lang.Object entity,
                               MediaType mediaType)

Builder pattern method to add a named field with an arbitrary media type and entity, and return this instance.

Parameters:

name - the control name.

entity - entity value for the new field

mediaType - media type for the new field

Returns:

this instance.

getField

public FormDataBodyPart getField(java.lang.String name)

Get a form data body part given a control name.

Parameters:

name - the control name.

Returns:

the form data body part, otherwise null if no part is present with the given control name. If more that one part is present with the same control name, then the first part that occurs is returned.

getFields

public java.util.List<FormDataBodyPart> getFields(java.lang.String name)

Get a list of one or more form data body parts given a control name.

Parameters:

name - the control name.

Returns:

the list of form data body parts, otherwise null if no parts are present with the given control name.

getFields

public java.util.Map<java.lang.String,java.util.List<FormDataBodyPart>> getFields()

Get a map of form data body parts where the key is the control name and the value is a list of one or more form data body parts.

Returns:

return the map of form data body parts.

setMediaType

public void setMediaType(MediaType mediaType)

Disable changing the media type to anything other than multipart/form-data.

Overrides:

setMediaType in class MultiPart

Parameters:

mediaType - The proposed media type
