public class ObjectInfo

extends Data

ObjectInfo provides metadata such as image and thumbnail sizes for image objects; it describes associations; and identifies additional object types such as audio clips.

Note that in addition to the image formats identified here, devices could also support proprietary formats except for use with thumbnail images.

Constructor Summary

ObjectInfo(java.net.URLConnection conn, DeviceInfo devInfo, NameFactory f)
Construct an ObjectInfo data packet using the object at the other end of the specified connection.

Method Summary

java.lang.String	getCodeName(int code) Subclasses override this to map PTP codes to their names; the results are always interned strings, so that they can be efficiently compared ("=", "!=") against constants.
int	getLength() Returns the overall length of this data block, including header.
boolean	isImage() Returns true for format codes that have the image type bit set.
boolean	isVideo() Returns true for some recognized video format codes.

Constructor Detail

ObjectInfo

public ObjectInfo(java.net.URLConnection conn,
                  DeviceInfo devInfo,
                  NameFactory f)

Construct an ObjectInfo data packet using the object at the other end of the specified connection.

Throws:

java.lang.IllegalArgumentException - if the object uses an image format the device doesn't support, or if the object's content type is not recognized.

Method Detail

getLength

public int getLength()

Description copied from class: Container

Returns the overall length of this data block, including header.

Overrides:

getLength in class Container

isImage

public boolean isImage()

Returns true for format codes that have the image type bit set.

isVideo

public boolean isVideo()

Returns true for some recognized video format codes.

getCodeName

public java.lang.String getCodeName(int code)

Description copied from class: Container

Subclasses override this to map PTP codes to their names; the results are always interned strings, so that they can be efficiently compared ("=", "!=") against constants. Such per-instance methods permit type-specific subclasses (and vendor extensions) to name their code values, invoking superclass methods to name all other codes.

Overrides:

getCodeName in class Data
