For example: Schema.DescribeSObjectResult R = Account.SObjectType.getDescribe(); List C = R.getChildRelationships(); ## ChildRelationship Methods The following are methods for ChildRelationship. All are instance methods. - **[getChildSObject()](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_ChildRelationship.htm#apex_Schema_ChildRelationship_getChildSObject)** Returns the token of the child sObject on which there is a foreign key back to the parent sObject. - **[getField()](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_ChildRelationship.htm#apex_Schema_ChildRelationship_getField)** Returns the token of the field that has a foreign key back to the parent sObject. - **[getRelationshipName()](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_ChildRelationship.htm#apex_Schema_ChildRelationship_getRelationshipName)** Returns the name of the relationship. - **[isCascadeDelete()](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_ChildRelationship.htm#apex_Schema_ChildRelationship_isCascadeDelete)** Returns true if the child object is deleted when the parent object is deleted, false otherwise. - **[isDeprecatedAndHidden()](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_ChildRelationship.htm#apex_Schema_ChildRelationship_isDeprecatedAndHidden)** Reserved for future use. - **[isRestrictedDelete()](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_ChildRelationship.htm#apex_Schema_ChildRelationship_isRestrictedDelete)** Returns true if the parent object can't be deleted because it is referenced by a child object, false otherwise. ### getChildSObject() Returns the token of the child sObject on which there is a foreign key back to the parent sObject. #### Signature public Schema.SObjectType getChildSObject() #### Return Value Type: [Schema.SObjectType](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_SObjectType.htm#apex_class_Schema_SObjectType "A Schema.sObjectType object is returned from the field describe result using the getReferenceTo method, or from the sObject describe result using the getSObjectType method.") ### getField() Returns the token of the field that has a foreign key back to the parent sObject. #### Signature public Schema.SObjectField getField() #### Return Value Type: [Schema.SObjectField](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_Schema_SObjectField.htm#apex_class_Schema_SObjectField "A Schema.sObjectField object is returned from the field describe result using the getController and getSObjectField methods.") ### getRelationshipName() Returns the name of the relationship. #### Signature public String getRelationshipName() #### Return Value Type: [String](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_methods_system_string.htm#apex_methods_system_string "Contains methods for the String primitive data type.") ### isCascadeDelete() Returns true if the child object is deleted when the parent object is deleted, false otherwise. #### Signature public Boolean isCascadeDelete() #### Return Value Type: [Boolean](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_methods_system_boolean.htm#apex_methods_system_boolean "Contains methods for the Boolean primitive data type.") ### isDeprecatedAndHidden() Reserved for future use. #### Signature public Boolean isDeprecatedAndHidden() #### Return Value Type: [Boolean](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_methods_system_boolean.htm#apex_methods_system_boolean "Contains methods for the Boolean primitive data type.") ### isRestrictedDelete() Returns true if the parent object can't be deleted because it is referenced by a child object, false otherwise. #### Signature public Boolean isRestrictedDelete() #### Return Value Type: [Boolean](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_methods_system_boolean.htm#apex_methods_system_boolean "Contains methods for the Boolean primitive data type.")
