| Method Detail |
escapeText
public static java.lang.String escapeText(int end, java.lang.String str, char c)
- Processes text to be sent to the CVW server so that given
a character, all occurences of it will be escaped.
replaceCRsForServer
public static java.lang.String replaceCRsForServer(int end, java.lang.String str)
- Changed >>!<< with "\n&quoyt;
prepTextForServer
public static java.lang.String prepTextForServer(java.lang.String oldText)
- Prepares the text being sent to the CVW serverby searching for special
characters and escaping them and then wrapping the entire text in
double quotes. Currently, the characters needing to be
escaped are: \n, \r, \, ", :
parseBarDelimitedStringFromServer
public static java.lang.String parseBarDelimitedStringFromServer(java.lang.String barDelim)
- Parses through a bar delimited string from the CVW server, checking for
beginning and ending bars and adds space between consecutive bars.
known .. if the first user has a blank fullname, it gets stripped
from the mcp processor, and the string starts w/a |.
known .. if the last user has a blank fullname, it gets stripped
from the mcp processor, and the string ends w/a |.
getInstance
public static CVWServerComm getInstance()
sendMCPCmdToServer
public static void sendMCPCmdToServer(java.lang.String cmd)
- Sends a MCP command to CVW server with no parameters.
sendMCPCmdToServer
public static void sendMCPCmdToServer(java.lang.String cmd, java.lang.String rest)
- Sends a MCP command to CVW server with provided parameters,
inserting the auth code.
sendRawCmdToServer
public static void sendRawCmdToServer(java.lang.String cmd)
- Sends a non-mcp command to the CVW server.
startThread
public void startThread()
- Starts the communication thread.
getSocket
public java.net.Socket getSocket()
- Returns the current socket to the CVW server.
getServerName
public java.lang.String getServerName()
- Returns the name of the CVW server.
getServerHost
public java.lang.String getServerHost()
- Returns the host name of the CVW server.
getServerPort
public int getServerPort()
- Returns the port of the CVW server.
connectionValid
public boolean connectionValid()
- Returns whether the connection to the CVW server is valid.
openConnection
public void openConnection()
- Opens the connection to the CVW server.
closeConnection
public void closeConnection()
- Closes the connection to the CVW server.
displayError
public void displayError(java.lang.String errorString, java.lang.String title)
- Displays an error in a dialog box.
sendIdle
public void sendIdle(java.lang.String text)
- Sends the idle command to the CVW server and sets the idle state
sendCmdToServer
public void sendCmdToServer(java.lang.String cmd)
- Sends a command to the CVW server if the connection is valid.
receiveLine
public void receiveLine(java.lang.String theLine)
- Receives communication from the CVW server one line at a time. This does some
processing if the line does not start with #$#, otherwise it is processed by
the processMCP method.
processMCP
public void processMCP(java.lang.String theLine)
- Processes the communication line which represents MCP from the CVW server
converting it to a MCP command and then acting upon the MCP.
parseMCP
public MCPCommand parseMCP(java.lang.String mcpLine)
- Creates a MCP command based on a line of commuication from the CVW server. This
basically looks for key: value pairs and creates a hashtable of them.
removeEscapeChars
public java.lang.String removeEscapeChars(int end, java.lang.String str)
- Removes the escape characters that the CVW server addes to the values
in the key: value pairs of the MCP command.
removeQuotesFromServer
public java.lang.String removeQuotesFromServer(int end, java.lang.String str)
- Removes double quotes (") that the CVW server addes whenever
a value in the key:value pair needs it.
