com.sun.jersey.multipart.file.StreamDataBodyPart

public class StreamDataBodyPart
extends FormDataBodyPart

Represents an InputStream based file submission as a part of the multipart/form-data.

It sets the InputStream as a body part with the default MediaType.APPLICATION_OCTET_STREAM_TYPE (if not specified by the user).
Note that the MIME type of the entity cannot be automatically predicted as in case of FileDataBodyPart.

The filename of the attachment is set by the user or defaults to the part's name.

Constructor Detail

StreamDataBodyPart

public StreamDataBodyPart()

Default constructor which forces user to manually set the required (name and streamEntity) properties.

setFilename(String) can be used to set user-specified attachment filename instead of the default one.

FormDataBodyPart.setName(String), setStreamEntity(InputStream, MediaType)

StreamDataBodyPart

public StreamDataBodyPart(String name,
                  InputStream streamEntity)

Convenience constructor which assumes the defaults for: filename (part's name) and mediaType ( MediaType.APPLICATION_OCTET_STREAM_TYPE).

It builds the requested body part and makes the part ready for submission.

Parameters:

name - name of the form-data field

streamEntity - entity to be set as a body part

StreamDataBodyPart

public StreamDataBodyPart(String name,
                  InputStream streamEntity,
                  String filename)

Convenience constructor which assumes the defaults for the mediaType (MediaType.APPLICATION_OCTET_STREAM_TYPE).

It builds the requested body part and makes the part ready for submission.

Parameters:

name - name of the form-data field

streamEntity - entity to be set as a body part

filename - filename of the sent attachment (to be set as a part of content-disposition)

StreamDataBodyPart

public StreamDataBodyPart(String name,
                  InputStream streamEntity,
                  String filename,
                  javax.ws.rs.core.MediaType mediaType)

All-arguments constructor with all requested parameters set by the caller.

It builds the requested body part and makes the part ready for submission.

Parameters:

name - name of the form-data field

streamEntity - entity to be set as a body part

filename - filename of the sent attachment (to be set as a part of content-disposition)

mediaType - MIME type of the streamEntity attachment

Throws:

IllegalArgumentException - if name or streamEntity are null.

setStreamEntity(InputStream, MediaType)

setStreamEntity

public void setStreamEntity(InputStream streamEntity)

Allows to explicitly set the body part entity. This method assumes the default MediaType.APPLICATION_OCTET_STREAM MIME type and doesn't have to be invoked if one of the non-default constructors was already called.

Either this method or setStreamEntity(InputStream, MediaType) must be invoked if the default constructor was called.

Parameters:

streamEntity - entity to be set as a body part

setStreamEntity

public void setStreamEntity(InputStream streamEntity,
                   javax.ws.rs.core.MediaType mediaType)

Allows to explicitly set the value and the MIME type of the body part entity. This method doesn't have to be invoked if one of the non-default constructors was already called.

Either this method or setStreamEntity(InputStream) must be invoked if the default constructor was called.

Parameters:

streamEntity - entity to be set as a body part

mediaType - MIME type of the streamEntity attachment

buildContentDisposition

protected FormDataContentDisposition buildContentDisposition()

getDefaultMediaType

protected static javax.ws.rs.core.MediaType getDefaultMediaType()

Gets the default MediaType to be used if the user didn't specify any.

Returns:

default MediaType for this body part entity.

setFilename

public void setFilename(String filename)

Sets the body part entity filename value to be used in the content-disposition header.

Parameters:

filename - name to be used

getStreamEntity

public InputStream getStreamEntity()

Gets the underlying stream entity which will form the body part entity.

Returns:

underlying stream.

getFilename

public String getFilename()

Gets the filename value which is to be used in the content-disposition header of this body part entity.

Returns:

filename
