Class FormDataBodyPart

java.lang.Object

org.glassfish.jersey.media.multipart.BodyPart

org.glassfish.jersey.media.multipart.FormDataBodyPart

Direct Known Subclasses:

FileDataBodyPart, StreamDataBodyPart

public class FormDataBodyPart
extends BodyPart

Subclass of BodyPart 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:

• Property accessor to retrieve the control name.
• Property accessor to retrieve the field value for a simple String field.
• Convenience accessor to retrieve the field value after conversion through an appropriate MessageBodyReader.

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

• Convenience constructors for named fields with either simple string values, or arbitrary entities and media types.
• Property accessor to set the control name.
• Property accessor to set the field value for a simple String field.
• Convenience accessor to set the media type and value of a "file" field.

Method Detail

getFormDataContentDisposition

public FormDataContentDisposition getFormDataContentDisposition()

Gets the form data content disposition.

Returns:

the form data content disposition.

setFormDataContentDisposition

public void setFormDataContentDisposition(FormDataContentDisposition formDataContentDisposition)

Sets the form data content disposition.

Parameters:

formDataContentDisposition - the form data content disposition.

getContentDisposition

public ContentDisposition getContentDisposition()

Overrides the behaviour on BodyPart to ensure that only instances of FormDataContentDisposition can be obtained.

Overrides:

getContentDisposition in class BodyPart

Returns:

the content disposition.

Throws:

IllegalArgumentException - if the content disposition header cannot be parsed.

setContentDisposition

public void setContentDisposition(ContentDisposition contentDisposition)

Overrides the behaviour on BodyPart to ensure that only instances of FormDataContentDisposition can be set.

Overrides:

setContentDisposition in class BodyPart

Parameters:

contentDisposition - the content disposition which must be an instance of FormDataContentDisposition.

Throws:

IllegalArgumentException - if the content disposition is not an instance of FormDataContentDisposition.

Returns:

the control name.

setName

public void setName(String name)

Sets the control name.

Parameters:

name - the control name.

getValue

public String getValue()

Gets the field value for this body part. This should be called only on body parts representing simple field values.

Returns:

the simple field value.

Throws:

javax.ws.rs.ProcessingException - if an IO error arises during reading the value.

IllegalStateException - if called on a body part with a media type other than text/plain

getValueAs

public <T> T getValueAs(Class<T> clazz)

Gets the field value after appropriate conversion to the requested type. This is useful only when the containing FormDataMultiPart instance has been received, which causes the providers property to have been set.

Type Parameters:

T - the type of the field value.

Parameters:

clazz - Desired class into which the field value should be converted.

Returns:

the field value.

Throws:

javax.ws.rs.ProcessingException - if an IO error arises during reading an entity.

Parameters:

value - the field value.

Throws:

setValue

public void setValue(javax.ws.rs.core.MediaType mediaType,

Sets the field media type and value for this body part.

Parameters:

mediaType - the media type for this field value.

value - the field value as a Java object.

isSimple

public boolean isSimple()
