这种样式方便在wtk中显示，在实际的设备中进行测试的时候，你可能希望把分析输出到串口或者通过网络发到servlet，你可以通过定义自己的类实现实现Logger接口，然后把这个类作为RMSAnalyzer构造器的参数。下面是源代码。
package com.ericgiguere;
import java.io.*;
import javax.microedition.rms.*;
// Analyzes the contents of a record store.
// By default prints the analysis to System.out,
// but you can change this by implementing your
// own Logger.
public class RMSAnalyzer {
// The logging interface.
public interface Logger {
void logEnd( RecordStore rs );
void logException( String name, Throwable e );
void logException( RecordStore rs, Throwable e );
void logRecord( RecordStore rs, int id,
byte[] data, int size );
void logStart( RecordStore rs );
}
private Logger logger;
// Constructs an analyzer that logs to System.out.
public RMSAnalyzer(){
this( null );
}
// Constructs an analyzer that logs to the given logger.
public RMSAnalyzer( Logger logger ){
this.logger = ( logger != null ) ? logger :
new SystemLogger();
}
// Open the record stores owned by this MIDlet suite
// and analyze their contents.
public void analyzeAll(){
String[] names = RecordStore.listRecordStores();
for( int i = 0;
names != null && i < names.length;
++i ){
analyze( names[i] );
}
}
// Open a record store by name and analyze its contents.
public void analyze( String rsName ){
RecordStore rs = null;
try {
rs = RecordStore.openRecordStore( rsName, false );
analyze( rs );
} catch( RecordStoreException e ){
logger.logException( rsName, e );
} finally {
try {
rs.closeRecordStore();
} catch( RecordStoreException e ){
// Ignore this exception
}
}
}
// Analyze the contents of an open record store using
// a simple brute force search through the record store.
public synchronized void analyze( RecordStore rs ){
try {
logger.logStart( rs );
int lastID = rs.getNextRecordID();
int numRecords = rs.getNumRecords();
int count = 0;
byte[] data = null;
for( int id = 0;
id < lastID && count < numRecords;
++id ){
try {
int size = rs.getRecordSize( id );
// Make sure data array is big enough,
// plus add some for growth
if( data == null || data.length < size ){
data = new byte[ size + 20 ];
}
rs.getRecord( id, data, 0 );
logger.logRecord( rs, id, data, size );
++count; // only increase if record exists
}
catch( InvalidRecordIDException e ){
// just ignore and move to the next one
}

}
}
} catch( RecordStoreException e ){

}
}
// A logger that outputs to a PrintStream.
public static class PrintStreamLogger implements Logger {
public static final int COLS_MIN = 10;
public static final int COLS_DEFAULT = 20;
private int cols;
private int numBytes;
private StringBuffer hBuf;
private StringBuffer cBuf;
private StringBuffer pBuf;
