  • Filtering is based on "Anding" i.e any one assigned filter fails its condition ,form fails to show on dashboard.
  • All filters should have a single string parameter constructor.It takes filter properties as input. This constructor can be used to initialize filter properties.
    Example:
    Code Block
    
package org.openmrs.module.formfilter.impl;

import java.lang.reflect.Field;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.openmrs.Patient;
import org.openmrs.User;
import org.openmrs.module.formfilter.FormFilterHandler;

/**
 * This class will provide patient age based form filter. 
 */

	protected Log log = LogFactory.getLog(getClass());
	
	/**
	 * Default Constructor
	 */
	public AgeFormFilter()
	{
		
	}
	
	/**
	 * Constructor sets class field values.
	 * @param properties ,string property from FormFilterProperty class in key=value based format 
	 * Example: minimumAge=value&maximumAge=value  
	 */
	public AgeFormFilter(String properties){
		for (String string : properties.split("&")) {
	        String str[]=string.split("=");
	        try {
	            Field field=this.getClass().getDeclaredField(str[0]);
	            field.set(this, (Object)Integer.parseInt(str[1]));
            }catch (Exception e) {
            	log.info(e);
            }
		}	

	}
	
	private int minimumAge;
	
	private int maximumAge;
