Field Summary protected  byte[] readBuffer      Source buffer which contains binary data of a data element. protected  long readPos      Current position at the source buffer. protected  byte[] writeBuffer      Destination buffer which collects binary data of a data element. protected  long writePos      Current position at the destination buffer. Constructor Summary   DataElementSerializer()      Constructs the serializer object. Method Summary  long getDataSize(DataElement data)      Returns the size of DataElement with service information to get the total size required to work with this DataElement.  long getPureDataSize(DataElement data)      Returns the size of DataElement without service information.  boolean readBoolean()      Reads boolean value from the connection.  byte readByte()      Reads 1-byte value from the connection.  byte[] readBytes(int size)      Reads given number of bytes from the connection. Parameters:   size - number of bytes to read.  DataElement readDataElement()      Creates a data element from the binary data in the read buffer.  int readInteger()      Reads 4-byte value from the connection.  long readLong()      Reads 8-byte value from the connection.  short readShort()      Reads 2-byte value from the connection.  UUID readUUID(int len)      Reads UUID of a given size. public synchronized  DataElement restore(byte[] data)      Constructs DataElement from byte array containing the element in serialized form. public synchronized  byte[] serialize(DataElement data)      Serializes given DataElement object, i.e.  void writeBoolean(boolean data)      Writes boolean data to the buffer. Writes only value given itself.  void writeByte(long data)      Writes 1-byte data to the buffer.  void writeBytes(byte[] data)      Writes given data to the connection.  void writeDataElement(DataElement data)      Writes given data element into the write buffer.  void writeInteger(int data)      Writes 4-byte data to the connection.  void writeLong(long data)      Writes 8-byte data to the connection.  void writeShort(short data)      Writes 2-byte data to the buffer. Field Detail readBuffer protected byte[] readBuffer(Code) Source buffer which contains binary data of a data element. readPos protected long readPos(Code) Current position at the source buffer. writeBuffer protected byte[] writeBuffer(Code) Destination buffer which collects binary data of a data element. writePos protected long writePos(Code) Current position at the destination buffer. Constructor Detail DataElementSerializer DataElementSerializer()(Code) Constructs the serializer object. Method Detail getDataSize long getDataSize(DataElement data)(Code) Returns the size of DataElement with service information to get the total size required to work with this DataElement. Parameters:   data - the data element to get packet size for number of bytes needed to store given data element getPureDataSize long getPureDataSize(DataElement data)(Code) Returns the size of DataElement without service information. Parameters:   data - the data element to get pure data size for pure data size in bytes readBoolean boolean readBoolean() throws IOException(Code) Reads boolean value from the connection. boolean value recieved. throws:   IOException - if an I/O error occurs readByte byte readByte() throws IOException(Code) Reads 1-byte value from the connection. byte recieved. throws:   IOException - if an I/O error occurs readBytes byte[] readBytes(int size) throws IOException(Code) Reads given number of bytes from the connection. Parameters:   size - number of bytes to read. array of bytes read. throws:   IOException - if an I/O error occurs readDataElement DataElement readDataElement() throws IOException(Code) Creates a data element from the binary data in the read buffer. DataElement read throws:   IOException - if an I/O error occurs readInteger int readInteger() throws IOException(Code) Reads 4-byte value from the connection. int which is the 4 bytes read. throws:   IOException - if an I/O error occurs readLong long readLong() throws IOException(Code) Reads 8-byte value from the connection. long which is the 8 bytes read. throws:   IOException - if an I/O error occurs readShort short readShort() throws IOException(Code) Reads 2-byte value from the connection. short which is the 2 bytes read. throws:   IOException - if an I/O error occurs readUUID UUID readUUID(int len) throws IOException(Code) Reads UUID of a given size. Parameters:   len - number of bytes to read UUID created from len bytes throws:   IOException - if an I/O error occurs restore public synchronized DataElement restore(byte[] data) throws IOException(Code) Constructs DataElement from byte array containing the element in serialized form. Parameters:   data - byte array containing the element in serialized form DataElement constructed from the binary data throws:   IOException - if an I/O error occurs serialize public synchronized byte[] serialize(DataElement data) throws IOException(Code) Serializes given DataElement object, i.e. creates an array of bytes representing DataElement as described in Bluetooth Specification Version 1.2, vol 3, page 127. Parameters:   data - the data element to serialize an array containing the serialized data element throws:   IOException - if an I/O error occurs writeBoolean void writeBoolean(boolean data) throws IOException(Code) Writes boolean data to the buffer. Writes only value given itself. Note that boolean data header should be written before. Parameters:   data - boolean value to write. throws:   IOException - if an I/O error occurs writeByte void writeByte(long data) throws IOException(Code) Writes 1-byte data to the buffer. Parameters:   data - byte value to write. throws:   IOException - if an I/O error occurs writeBytes void writeBytes(byte[] data) throws IOException(Code) Writes given data to the connection. Parameters:   data - bytes to write. throws:   IOException - if an I/O error occurs writeDataElement void writeDataElement(DataElement data) throws IOException(Code) Writes given data element into the write buffer. Parameters:   data - the data element to write throws:   IOException - if an I/O error occurs writeInteger void writeInteger(int data) throws IOException(Code) Writes 4-byte data to the connection. Parameters:   data - 4-byte value to write. throws:   IOException - if an I/O error occurs writeLong void writeLong(long data) throws IOException(Code) Writes 8-byte data to the connection.
