Constructor Detail

PersistentExceptionNode

public PersistentExceptionNode(long address)

Create an object of rule's exception, using an address in the binary file.

Parameters:

address - the address of current persistent exception node

PersistentExceptionNode

public PersistentExceptionNode(long address,
                               long next)

Create an object of rule's exception, using an address in the binary file and the address of the next exception.

Parameters:

address - the address of current persistent exception node

next - address of the next node of current node

PersistentExceptionNode

public PersistentExceptionNode(java.lang.String key,
                               java.lang.String value)

Create an object of rule's exception, using a key value pair.

Parameters:

key - the string for matching pattern

value - the string for changing pattern

Method Detail

GetKey

public java.lang.String GetKey()

Get the string of matching pattern of the rule's exception.

Returns:

the string of matching pattern of the rule's exception

GetValue

public java.lang.String GetValue()

Get the string of changing pattern of the rule's exception.

Returns:

the string of changing pattern of the rule's exception

WriteData

public void WriteData(java.io.RandomAccessFile raf)
               throws java.io.IOException

Write the matching and changing string partterns to a specific binary file.

Overrides:

WriteData in class PersistentListNode

Parameters:

raf - the object of random access file

Overrides:

ReadData in class PersistentListNode

Parameters:

raf - the object of random access file

Throws:

java.io.IOException - if problems of reading data to random access file happen.

GetNode

public static PersistentListNode GetNode(java.io.RandomAccessFile raf,
                                         long address)
                                  throws java.io.IOException

Get data of a persistent list node at a specific addrss of a specific binary file.

Parameters:

raf - the object of random access file

address - the address of the persistent list node to be retrieved

Returns:

persistent list node for the specified address in RAF

Throws:

java.io.IOException - if problems of accessing random access file happen.

PrintList

public static void PrintList(java.lang.String exceptionPath,
                             long address)
                      throws java.io.IOException

Print the detail information of rule's exceptions for a specific file at a specific address.

Parameters:

exceptionPath - the path/file name of the rule's exceptions to be printed

address - the address of the rule's exceptions in a random access file

Throws:

java.io.IOException - if problems of accessing random access file happen.
