create a ralation ship object

[hadesgrid]

Hello Stephen

I am tryind to create a ralation ship object

Relationship usesRel = Relationship.builder()
	                .relationshipType("uses")
	                .created(Instant.now())
	                .sourceRef(AttackPattern.builder()
	                        .name("Some Attack Pattern 1")
	                        .build())
	                .targetRef(Malware.builder()
	                        .name("dog")
	                        .addLabels("worm")
	                        .build())
	                .build();

the Relationship class is

ackage io.digitalstate.stix.sro.objects;

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonPOJOBuilder;

import io.digitalstate.stix.bundle.Bundle;
import io.digitalstate.stix.sdo.DomainObject;

@JsonDeserialize(builder = Relationship.Builder.class)
public class Relationship {
	
	private String relationshipType;
	private String description;
	private DomainObject sourceRef;
	private DomainObject targetRef;
	
	private Relationship(String relationshipType,	String description,	DomainObject sourceRef,	DomainObject targetRef) {
		this.relationshipType=relationshipType;
		this.description=description;
		this.sourceRef=sourceRef;
		this.targetRef=targetRef;
		
	}
	
	@JsonPOJOBuilder
	public static class Builder{
		String relationshipType1;
		String description;
		DomainObject sourceRef;
		DomainObject targetRef;
		
		Builder setRelationshipType (String relationshipType) {
            this.relationshipType1 = relationshipType;
            return this;
        }
		
		Builder setDescription (String description) {
            this.description = description;
            return this;
        }
		
		Builder setSourceRef (DomainObject sourceRef) {
            this.sourceRef = sourceRef;
            return this;
        }
		
		Builder setTargetRef (DomainObject targetRef) {
            this.targetRef = targetRef;
            return this;
        }
		
		public Relationship build() {
            return new Relationship(relationshipType1,description,sourceRef,targetRef);
        }
	}

}

my question is ¿how do you implement the method builder() in the Relationship class?
many thanks in advance

What is the error you are receiving?

Hello Stephen,
Thank you againg for you help.
I am trying to figure out how to construct the missing classes form the repository, so that I can serilize and deserialize a stix json

for this example :

Relationship usesRel = Relationship.builder()
	                .relationshipType("uses")
	                .created(Instant.now())
	                .sourceRef(AttackPattern.builder() //The method sourceRef(DomainObject) in the type Relationship.Builder is not 
                                                                                  //applicable for the arguments (AttackPattern)
	                        .name("Some Attack Pattern 1")
	                        .build())
	                .targetRef(Malware.builder()
	                        .name("dog")
	                        .addLabels("worm")
	                        .build())
	                .build();

I need the following missing classes:
Relationship
AttackPattern
Malware

This is the way that I have constructed them.

Relationship

@JsonDeserialize(builder = Relationship.Builder.class)
public class Relationship {
	

	public static Builder builder() {
	    return new Builder();
	}
	
	private Instant created;
	private String relationshipType;
	private String description;	
	private DomainObject sourceRef;
	private DomainObject targetRef;
	
	
private Relationship(Instant created ,String relationshipType,	String description,	DomainObject sourceRef,	DomainObject targetRef) {
		this.created=created;
		this.relationshipType=relationshipType;
		this.description=description;
		this.sourceRef=sourceRef;
		this.targetRef=targetRef;
		
	}
	
	@JsonPOJOBuilder
	public static class Builder{
		Instant created;
		String relationshipType;
		String description;
		DomainObject sourceRef;
		DomainObject targetRef;
		
		public Builder relationshipType (String relationshipType) {
            this.relationshipType = relationshipType;
            return this;
        }
		
		public Builder created (Instant instant) {
            this.created = instant;
            return this;
        }
		
		
		public Builder description (String description) {
            this.description = description;
            return this;
        }
		
		public Builder sourceRef (DomainObject sourceRef) {
            this.sourceRef = sourceRef;
            return this;
        }
		
		public Builder targetRef (DomainObject targetRef) {
            this.targetRef = targetRef;
            return this;
        }
		
		public Relationship build() {
            return new Relationship(created,relationshipType,description,sourceRef,targetRef);
        }

	}

	@Override
	public String toString() {
		return "Relationship [created=" + created + ", relationshipType=" + relationshipType + ", description="
				+ description + ", sourceRef=" + sourceRef + ", targetRef=" + targetRef + "]";
	}
			
	public String toJsonString() {
		try {
			
			 JsonNode response = StixParsers.getJsonMapper().valueToTree(this);
		      ObjectNode responseNode = (ObjectNode) response;
		        
			//ObjectMapper mapper = new ObjectMapper();
			//String realtion_s= mapper.writeValueAsString(this);
			//ObjectNode json = (ObjectNode) mapper.readTree(realtion_s);
			//json.remove("field");
			return responseNode.toString();
		}catch(Exception e) {
		}
		return null;
	}	
}

//// AttackPattern class

@JsonDeserialize(builder = AttackPattern.Builder.class)
public class AttackPattern {
	
	public static Builder builder() {
	    return new Builder();
	}
	
	private String name;
	private String description;
	private Set<KillChainPhaseType>  killChainPhases;
	
	private  AttackPattern(String name ,	 String  description  ,		  Set<KillChainPhaseType> killChainPhases) {
		this.name = name;
		this.description = description;
		this.killChainPhases = killChainPhases;		
	}
		
	@JsonPOJOBuilder
	public static class Builder
	  {
		 String name;
		 String description;
		 Set<KillChainPhaseType>  killChainPhases;
    	
    	public Builder name(String name) {
            this.name = name;
            return this;
        }
    	
    	public Builder description(String description) {
            this.description = description;
            return this;
        }
    	
    	public Builder killChainPhases(Set<KillChainPhaseType> killChainPhases) {
            this.killChainPhases = killChainPhases;
            return this;
        }
    	
    	public AttackPattern build() {
            return new AttackPattern(name,description,killChainPhases);
        }
	  }

	public String toJsonString() {
		try {
			
			 JsonNode response = StixParsers.getJsonMapper().valueToTree(this);
		      ObjectNode responseNode = (ObjectNode) response;
		        
			//ObjectMapper mapper = new ObjectMapper();
			//String realtion_s= mapper.writeValueAsString(this);
			//ObjectNode json = (ObjectNode) mapper.readTree(realtion_s);
			//json.remove("field");
			return responseNode.toString();
		}catch(Exception e) {
		}
		return null;
	}	
	
	@Override
	public String toString() {
		return "AttackPattern [name=" + name + ", description=" + description + ", killChainPhases=" + killChainPhases
				+ "]";
	}
}

Malware class

@JsonDeserialize(builder = Malware.Builder.class)
public class Malware {
	
	public static Builder builder() {
	    return new Builder();
	}
	private String labels;
	private String  name;
	private String description;
	private  Set<KillChainPhaseType>  killChainPhases;
	
	public Malware(String labels, String name, String description, Set<KillChainPhaseType> killChainPhases) {
		super();
		this.labels = labels;
		this.name = name;
		this.description = description;
		this.killChainPhases = killChainPhases;
	}
	
	@JsonPOJOBuilder
	public static class Builder
	  {
		String labels;
		String  name;
		String description;
		Set<KillChainPhaseType>  killChainPhases;
		
		public Builder addLabels(String labels) {
            this.labels = labels;
            return this;
        }
    	
		public Builder name(String name) {
            this.name = name;
            return this;
        }
    	
		public Builder description(String description) {
            this.description = description;
            return this;
        }
    	
    	
		public Builder killChainPhases( Set<KillChainPhaseType> killChainPhases) {
            this.killChainPhases = killChainPhases;
            return this;
        }
    	
    	public Malware build() {
            return new Malware(labels,name,description,killChainPhases);
        }
	  }
	
	public String toJsonString() {
		try {
			
			 JsonNode response = StixParsers.getJsonMapper().valueToTree(this);
		      ObjectNode responseNode = (ObjectNode) response;
		        
			//ObjectMapper mapper = new ObjectMapper();
			//String realtion_s= mapper.writeValueAsString(this);
			//ObjectNode json = (ObjectNode) mapper.readTree(realtion_s);
			//json.remove("field");
			return responseNode.toString();
		}catch(Exception e) {
		}
		return null;
	}

	@Override
	public String toString() {
		return "Malware [labels=" + labels + ", name=" + name + ", description=" + description + ", killChainPhases="
				+ killChainPhases + "]";
	}	
	
	
	
}

When i calling

Relationship usesRel = Relationship.builder()
	                .relationshipType("uses")
	                .created(Instant.now())
	                .sourceRef(AttackPattern.builder() 
	                        .name("Some Attack Pattern 1")
	                        .build())
	                .targetRef(Malware.builder()
	                        .name("dog")
	                        .addLabels("worm")
	                        .build())
	                .build();

the line
.sourceRef(AttackPattern.builder()

is showing the error
The method sourceRef(DomainObject) in the type Relationship.Builder is not applicable for the arguments (AttackPattern)

so it does with this line

.targetRef(Malware.builder()

what I am doing wrong? how can I construct the json?

many thanks in advance
