Constructor Summary

Constructors

Constructor	Description
FileDataBodyPart()	A no-args constructor which expects its client to set the values individually, the attributes to be set are fileEntity and name; the media type will be predicted from the fileEntity if not set explicitly.
FileDataBodyPart(String name, File fileEntity)	Constructs the body part with the provided name and file, it predicts the MediaType of the file provided.
FileDataBodyPart(String name, File fileEntity, MediaType mediaType)	Constructs the body part with all the attributes set for its proper function.

Constructor Details

FileDataBodyPart

public FileDataBodyPart()

A no-args constructor which expects its client to set the values individually, the attributes to be set are fileEntity and name; the media type will be predicted from the fileEntity if not set explicitly.

FileDataBodyPart

public FileDataBodyPart(String name,
 File fileEntity)

Constructs the body part with the provided name and file, it predicts the MediaType of the file provided. For the known media types client will not need to set the media type explicitly.

Parameters:

name - the name of body part.

fileEntity - the file that represents the entity.

See Also:

• MediaTypePredictor.getMediaTypeFromFile(java.io.File)
• FileDataBodyPart(java.lang.String, java.io.File, jakarta.ws.rs.core.MediaType)

FileDataBodyPart

public FileDataBodyPart(String name,
 File fileEntity,
 MediaType mediaType)
                 throws IllegalArgumentException

Constructs the body part with all the attributes set for its proper function. If this constructor is used to construct the body part then it is not required to set any other attributes for proper behavior.

Parameters:

name - the name of body part.

fileEntity - the file that represents the entity.

mediaType - the MediaType of the body part.

Throws:

IllegalArgumentException - if the fileEntity is null.

Method Details

Overrides:

setValue in class FormDataBodyPart

Parameters:

mediaType - the media type for this field value.

value - the field value as a Java object.

Throws:

UnsupportedOperationException - Operation not supported.

setEntity

public void setEntity(Object entity)
               throws UnsupportedOperationException

This operation is not supported from this implementation.

Overrides:
