Here is an example of how to use the BeanPropertyMap class in the com.fasterxml.jackson.databind package in Java:

import com.fasterxml.jackson.databind.BeanProperty;
import com.fasterxml.jackson.databind.BeanPropertyMap;
import com.fasterxml.jackson.databind.JavaType;

public class MyClass {

    public static void main(String[] args) {
        JavaType type = // construct the appropriate type
        BeanPropertyMap propertyMap = BeanPropertyMap.construct(type, true, null);
        for (BeanProperty prop : propertyMap) {
            // do something with the property
        }
    }
}

In this example, an instance of JavaType is constructed, and then used to create an instance of BeanPropertyMap using the construct method. This propertyMap object can then be used to iterate through the properties of the specified Java type.

Each property will be represented by an instance of BeanProperty class, which you can use to access the property name, type, annotation and other useful information.

Keep in mind that this is just an example, you can use BeanPropertyMap class in different way based on your requirement.
