Constructor Detail WrapperRepresentation public WrapperRepresentation(Representation wrappedRepresentation)(Code) Constructor. Parameters:   wrappedRepresentation - The wrapped representation. Method Detail getChannel public ReadableByteChannel getChannel() throws IOException(Code) Returns a channel with the representation's content. If it is supported by a file, a read-only instance of FileChannel is returned. This method is ensured to return a fresh channel for each invocation unless it is a transient representation, in which case null is returned. A channel with the representation's content. throws:   IOException - getCharacterSet public CharacterSet getCharacterSet()(Code) Returns the character set or null if not applicable. The character set or null if not applicable. getEncodings public List<Encoding> getEncodings()(Code) Returns the list of encodings. The list of encodings. getExpirationDate public Date getExpirationDate()(Code) Returns the future date when this representation expire. If this information is not known, returns null. The expiration date. getIdentifier public Reference getIdentifier()(Code) Returns the official identifier. The official identifier. getLanguages public List<Language> getLanguages()(Code) Returns the list of languages. The list of languages. getMediaType public MediaType getMediaType()(Code) Returns the media type. The media type. getModificationDate public Date getModificationDate()(Code) Returns the last date when this representation was modified. If this information is not known, returns null. The modification date. getSize public long getSize()(Code) Returns the size in bytes if known, UNKNOWN_SIZE (-1) otherwise. The size in bytes if known, UNKNOWN_SIZE (-1) otherwise. getStream public InputStream getStream() throws IOException(Code) Returns a stream with the representation's content. This method is ensured to return a fresh stream for each invocation unless it is a transient representation, in which case null is returned. A stream with the representation's content. throws:   IOException - getTag public Tag getTag()(Code) Returns the tag. The tag. getText public String getText() throws IOException(Code) Converts the representation to a string value. Be careful when using this method as the conversion of large content to a string fully stored in memory can result in OutOfMemoryErrors being thrown. The representation as a string value. getWrappedRepresentation public Representation getWrappedRepresentation()(Code) Returns the wrapped representation. The wrapped representation. isAvailable public boolean isAvailable()(Code) Indicates if some fresh content is available, without having to actually call one of the content manipulation method like getStream() that would actually consume it. This is especially useful for transient representation whose content can only be accessed once. True if some fresh content is available. isTransient public boolean isTransient()(Code) Indicates if the representation's content is transient, which means that it can be obtained only once. This is often the case with representations transmitted via network sockets for example. In such case, if you need to read the content several times, you need to cache it first, for example into memory or into a file. True if the representation's content is transient. setAvailable public void setAvailable(boolean isAvailable)(Code) Indicates if some fresh content is available. Parameters:   isAvailable - True if some fresh content is available. setCharacterSet public void setCharacterSet(CharacterSet characterSet)(Code) Sets the character set or null if not applicable. Parameters:   characterSet - The character set or null if not applicable. setExpirationDate public void setExpirationDate(Date expirationDate)(Code) Sets the future date when this representation expire. If this information is not known, pass null. Parameters:   expirationDate - The expiration date. setIdentifier public void setIdentifier(Reference identifier)(Code) Sets the official identifier. Parameters:   identifier - The official identifier. setIdentifier public void setIdentifier(String identifierUri)(Code) Sets the official identifier from a URI string. Parameters:   identifierUri - The official identifier to parse. setMediaType public void setMediaType(MediaType mediaType)(Code) Sets the media type. Parameters:   mediaType - The media type. setModificationDate public void setModificationDate(Date modificationDate)(Code) Sets the last date when this representation was modified. If this information is not known, pass null. Parameters:   modificationDate - The modification date. setSize public void setSize(long expectedSize)(Code) Sets the expected size in bytes if known, -1 otherwise. Parameters:   expectedSize - The expected size in bytes if known, -1 otherwise. setTag public void setTag(Tag tag)(Code) Sets the tag. Parameters:   tag - The tag. setTransient public void setTransient(boolean isTransient)(Code) Indicates if the representation's content is transient. Parameters:   isTransient - True if the representation's content is transient. write public void write(OutputStream outputStream) throws IOException(Code) Writes the representation to a byte stream. This method is ensured to write the full content for each invocation unless it is a transient representation, in which case an exception is thrown. Parameters:   outputStream - The output stream. throws:   IOException - write public void write(WritableByteChannel writableChannel) throws IOException(Code) Writes the representation to a byte channel. This method is ensured to write the full content for each invocation unless it is a transient representation, in which case an exception is thrown.
