字号:
//创建读文件对象
classFileReader = new java.io.FileReader(ClassFile);
//读文件内容到hash表
while ( (intLength = classFileReader.read(chrBuffer)) != -1) {
classCounter++;
//填写hash表
classWord = String.valueOf(chrBuffer).trim();
System.out.println("[INFOR]读取类型种别码: [KEY: " + classCounter +
"][VALUE: " + classWord + "]");
this.ClassHash.put(Integer.toString(classCounter), classWord);
}
//关闭读文件对象
classFileReader.close();
}
else { //文件不存在
System.err.println("[ERROR]类型种别码文件不存在!");
}
}
catch (Exception e) {
e.printStackTrace(System.err);
}
}
}
7） 抽象扫描缓冲区工厂：BufferFactory.java（使用抽象工厂方法模式产生缓冲区对象）
//Source file: d:\\JAccidenceAnalyse\\Buffer\\BufferFactory.java
package JAccidenceAnalyse.Buffer;
public interface BufferFactory {
/**
* @return JAccidenceAnalyse.Buffer.ScanBuffer
* @roseuid 3D9BB6F0003E
*/
public ScanBuffer createScanBuffer(int size);
/**
* @return JAccidenceAnalyse.Buffer.InputBuffer
* @roseuid 3D9BB7090062
*/
public InputBuffer createInputBuffer(int size);
}
8） 缓冲区工厂：ConcreteScanBufferFactory.java（实现了抽象工厂）
//Source file: d:\\JAccidenceAnalyse\\Buffer\\ConcreteScanBufferFactory.java
package JAccidenceAnalyse.Buffer;
public class ConcreteScanBufferFactory
implements BufferFactory {
/**
* @roseuid 3D9BBA19006A
*/
public ConcreteScanBufferFactory() {
System.out.println("[INFOR]缓冲区工厂已经建立!");
}
/**
* @return JAccidenceAnalyse.Buffer.ScanBuffer
* @roseuid 3D9BAC01004E
*/
public ScanBuffer createScanBuffer(int size) {
System.out.println("[INFOR]创建扫描缓冲区!");
return new ScanBuffer(size);
}
/**
* @return JAccidenceAnalyse.Buffer.InputBuffer
* @roseuid 3D9BB6050267
*/
public InputBuffer createInputBuffer(int size) {
System.out.println("[INFOR]创建输入缓冲区!");
return new InputBuffer(size);
}
}
9） 缓冲区对象抽象接口：Buffer.java
//Source file: d:\\JAccidenceAnalyse\\Buffer\\Buffer.java
package JAccidenceAnalyse.Buffer;
//abstract buffer interface
public interface Buffer {
}
10） 输入缓冲区对象：InputBuffer.java
//Source file: d:\\JAccidenceAnalyse\\Buffer\\InputBuffer.java
package JAccidenceAnalyse.Buffer;
import java.io.*;
public class InputBuffer
implements Buffer {
public char[] Data;
/**
* @roseuid 3D9BBA1C0186
*/
public InputBuffer(int size) {
this.Data = new char[size];
}
}
11） 扫描缓冲区对象：ScanBuffer.java
//Source file: d:\\JAccidenceAnalyse\\Buffer\\ScanBuffer.java
package JAccidenceAnalyse.Buffer;
public class ScanBuffer
implements Buffer {
public char[] Data;
/**
* @roseuid 3D9BBA1A0314
*/
public ScanBuffer(int size) {
this.Data = new char[size];
}
}
12） 词法分析器配置文件：aaCfg.xml

13） 类型种别码文件：class.table
identity

.
14） 关键字表文件：reserve.table
while
do
public
class
static
new
void
int
do
for
int
System
15） 一个测试文件：aClass.java
public class aClass{
public void aMethod( int value ) {
System.out.println( value );
}
public static void main( String[] args ){
aClass foo = new aClass();
int i=0;
foo.aMethod(i);
i = i+1;
foo.aMethod(i);
}
}
