/**
* A connection between a debugger and a target VM which it debugs.
*
* <p> A Connection represents a bi-directional communication channel
* between a debugger and a target VM. A Connection is created when
* {@link TransportService TransportService} establishes a connection
* and successfully handshakes with a target VM. A TransportService
* implementation provides a reliable JDWP packet transportation service
* and consequently a Connection provides a reliable flow of JDWP packets
* between the debugger and the target VM. A Connection is stream oriented,
* that is, the JDWP packets written to a connection are read by the target VM
* in the order in which they were written. Similarly packets written
* to a Connection by the target VM are read by the debugger in the
* order in which they were written.
*
* <p> A connection is either open or closed. It is open upon creation,
* and remains open until it is closed. Once closed, it remains closed,
* and any attempt to invoke an I/O operation upon it will cause a
* {@link ClosedConnectionException} to be thrown. A connection can
* be tested by invoking the {@link #isOpen isOpen} method.
*
* <p> A Connection is safe for access by multiple concurrent threads,
* although at most one thread may be reading and at most one thread may
* be writing at any given time.

* Reads a packet from the target VM.

* <p> Attempts to read a JDWP packet from the target VM.
* A read operation may block indefinitely and only returns
* when it reads all bytes of a packet, or in the case of a
* transport service that is based on a stream-oriented
* communication protocol, the end of stream is encountered.
*
* <p> Reading a packet does not do any integrity checking on
* the packet aside from a check that the length of the packet
* (as indicated by the value of the {@code length} field, the
* first four bytes of the packet) is 11 or more bytes.
* If the value of the {@code length} value is less then 11

* end of stream is encountered. If end of stream is encountered
* after some, but not all bytes of a packet, are read then it

* thrown. The first byte of the packet is stored in element

/**
* Writes a packet to the target VM.
*
* <p> Attempts to write, or send, a JDWP packet to the target VM.
* A write operation only returns after writing the entire packet
* to the target VM. Writing the entire packet does not mean
* the entire packet has been transmitted to the target VM
* but rather that all bytes have been written to the
* transport service. A transport service based on a TCP/IP connection
* may, for example, buffer some or all of the packet before
* transmission on the network.
*
* <p> The byte array provided to this method should be laid out
* as per the <a
* href="{@docRoot}/../specs/jdwp/jdwp-spec.html">
* JDWP specification</a>. That is, all fields in the packet
* are in big endian order. The first byte, that is element
* {@code pkt[0]}, is the first byte of the {@code length} field.
* {@code pkt[1]} is the second byte of the {@code length} field,
* and so on.
*
* <p> Writing a packet does not do any integrity checking on
* the packet aside from checking the packet length. Checking
* the packet length requires checking that the value of the
* {@code length} field (as indicated by the first four bytes
* of the packet) is 11 or greater. Consequently the length of
* the byte array provided to this method, that is
* {@code pkt.length}, must be 11 or more, and must be equal
* or greater than the value of the {@code length} field. If the
* length of the byte array is greater than the value of
* the {@code length} field then all bytes from element
* {@code pkt[length]} onwards are ignored. In other words,
* any additional bytes that follow the packet in the byte
* array are ignored and will not be transmitted to the target
* VM.
*
* <p> A write operation may block or may complete immediately.
* The exact circumstances when an operation blocks depends on
* the transport service. In the case of a TCP/IP connection to
* the target VM, the writePacket method may block if there is
* network congestion or there is insufficient space to buffer
* the packet in the underlying network system.
*
* <p> This method may be invoked at any time. If another thread has
* already initiated a write operation upon this Connection then
* a subsequent invocation of this method will block until the first
* operation is complete.
*

* If the connection is closed, or another thread closes
* the connection while the write operation is in progress.

* If an I/O error occurs.

* If the value of the {@code length} field is invalid,
