Java Matcher hasTransparentBounds()用法及代码示例

Matcher类的hasTransparentBounds()方法用于检查此Matcher是否具有透明边界。通过透明边界，这意味着如果透明边界设置为true，则匹配器将针对超出区域边界的匹配模式进行匹配，以进行匹配。此方法返回一个声明相同的布尔值。

用法:

public boolean hasTransparentBounds()

参数：此方法不带参数。

返回值：此方法返回一个布尔值，说明此匹配器是否具有透明边界

下面的示例说明Matcher.hasTransparentBounds()方法：

示例1:

// Java code to illustrate hasTransparentBounds() method 
  
import java.util.regex.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Get the regex to be checked 
        String regex = "(Geeks)"; 
  
        // Create a pattern from regex 
        Pattern pattern 
            = Pattern.compile(regex); 
  
        // Get the String to be matched 
        String stringToBeMatched 
            = "GeeksForGeeks Geeks for For Geeks Geek"; 
  
        // Create a matcher for the input String 
        Matcher matcher 
            = pattern 
                  .matcher(stringToBeMatched); 
  
        // Check if this matcher 
        // has transparent bounds or not 
        // using hasTransparentBounds() method 
        System.out.println("Does this matcher"
                               + " has transparent bounds: "
                               + matcher 
                                     .hasTransparentBounds()); 
    } 
}

输出：

Does this matcher has transparent bounds: false

示例2:

// Java code to illustrate hasTransparentBounds() method 
  
import java.util.regex.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Get the regex to be checked 
        String regex = "(F*F)"; 
  
        // Create a pattern from regex 
        Pattern pattern 
            = Pattern.compile(regex); 
  
        // Get the String to be matched 
        String stringToBeMatched 
            = "GFGFGFGFGFGFGFGFGFG FGF GFG GFG FGF"; 
  
        // Create a matcher for the input String 
        Matcher matcher 
            = pattern 
                  .matcher(stringToBeMatched); 
  
        // set the transparent bounds to true 
        matcher = matcher 
                      .useTransparentBounds(true); 
  
        // Check if this matcher 
        // has transparent bounds or not 
        // using hasTransparentBounds() method 
        System.out.println("Does this matcher"
                               + " has transparent bounds: "
                               + matcher 
                                     .hasTransparentBounds()); 
    } 
}

输出：

Does this matcher has transparent bounds: true
