java.util.zip中Deflater类的getTotalIn()函数返回到目前为止提供的未压缩字节输入的总数。
函数签名:
public int getTotalIn()
用法:
d.getTotalIn();
参数:该函数不需要参数
返回类型:该函数返回一个int值,该值是输入的未压缩字节的总数。
异常:该函数不会引发任何异常
范例1:
// Java program to describe the use
// of getTotalIn() function
import java.util.zip.*;
import java.io.UnsupportedEncodingException;
class GFG {
public static void main(String args[])
throws UnsupportedEncodingException
{
// deflater
Deflater d = new Deflater();
// get the text
String pattern = "GeeksforGeeks", text = "";
// generate the text
for (int i = 0; i < 4; i++)
text += pattern;
// set the input for deflator
d.setInput(text.getBytes("UTF-8"));
// finish
d.finish();
// output bytes
byte output[] = new byte[1024];
// compress the data
int size = d.deflate(output);
// compressed String
System.out.println("Compressed String:"
+ new String(output)
+ "\n Size " + size);
// original String
System.out.println("Original String:"
+ text + "\n Size "
+ text.length());
// get the total number of uncompressed
// bytes input so far
System.out.println("Total Input value:"
+ d.getTotalIn());
// end
d.end();
}
}
输出:
Compressed String:x?sOM?.N?/r???q?? Size 21 Original String:GeeksforGeeksGeeksforGeeksGeeksforGeeksGeeksforGeeks Size 52 Total In value:52
注意: 当输入的长度大于整数.MAX_VALUE。然后结果可能溢出,我们应该改用getBytesRead()函数
