Constructor Detail

CConfigScanner

public CConfigScanner(java.lang.String filename,
                      ILogger iLogger)
               throws java.lang.Exception

This constructor initializes the input stream. It opens the specified file, creates the stream tokenizer and initializes it.

Throws:

java.lang.Exception

Method Detail

getDebugLevel

public static int getDebugLevel()

getTokenValue

public java.lang.String getTokenValue()

setDebugLevel

public static void setDebugLevel(int debugLevel)

nextToken

public int nextToken()
              throws java.lang.Exception

This function retrieves the next token and updates m_tokenValue.

Returns:

A constant representing the next token. m_tokenValue is updated according to the next token's value. If m_pushBack was set to true (meaning that the token read last was to be pushed back) then the same token is returned the next time nextToken is called.

Throws:

java.lang.Exception

pushBack

public boolean pushBack()

close

public void close()

This function is called to close the scanner's input stream.

error

protected void error(java.lang.String fName,
                     java.lang.String msg)

debug

protected void debug(java.lang.String fName,
                     java.lang.String msg)
