An active TCB in an EDX virtual machine. This provides shortcuts for accessing TCB fields and memory in the same partition. It is a seperate class to keep it Thread safe. It is not an inner class because JDK compiler bugs don't allow blank final variables when inner classes are present.

Summary  |  Top

   public final void copyIn(int addr, 
                            byte[] b, 
                            int off, 
                            int len) 

Copy part of a byte array into EDX memory.

   public final void copyOut(int addr, 
                             byte[] b, 
                             int off, 
                             int len) 

Copy EDX memory into a byte array.

   public final byte[] getBytes(int addr, 
                                int len) 

Return a copy in a byte[] of a portion of EDX memory.

   public final void putBytes(int addr, 
                              byte[] b) 

Copy a byte[] into EDX memory.

   public final String getText(int addr) 

Return an EDX TEXT object as a String. No blanks are stripped. The length of the String is taken from the byte at addr - 1.

   public final void putText(int addr, 
                             String val) 

Set the value of an EDX TEXT object. The length must be less than the byte at addr - 2. The byte at addr - 1 is set to the length. The remaining bytes up to the max length at addr - 2 are set to EBCDIC blank.

   public final String etoa(int addr, 
                            int len) 

Return an EBCDIC character field as a String. No blanks are stripped, you can call trim() if desired.

   public final void atoe(int addr, 
                          int len, 
                          String s) 

Set an EBCDIC char field from a String. The String will be truncated or padded with blanks to fit in len EBCDIC bytes.

   public final int getDword(int addr) 

Return the DWORD at an EDX address in the active partition.

   public final void putDword(int addr, 
                              int val) 

Store a DWORD at an EDX address in the active partition.

   public final char getAddr(int addr) 

Return the unsigned WORD at an EDX address in the active partition.

   public final void putWord(int addr, 
                             int val) 

Set the WORD at an EDX address in the active partition of this TCB.

   public final void putByte(int addr, 
                             int val) 

Set the BYTE at an EDX address in the active partition of this TCB.

   public final short getWord(int addr) 

Return the WORD at an EDX address in the active partition.

   public final byte getByte(int addr) 

Return the BYTE at an EDX address in the active partition.

   public final void ready()  throws EDXException

Wakeup this TCB, which is presumably waiting for this external process.

   public final void post(int ecb, 
                          int code)  throws EDXException

   public final void reset(int ecb)  throws EDXException

   public final short gtcbw(int offset) 

   public final char gtcba(int offset) 

   public final void ptcbw(int offset, 
                           int val) 

   public CCB getCCB() 

Return the EDX CCB currently assigned to this TCB.

   public final PROG getPROG() 

Return the EDX Program this TCB is part of.
