## Nested Models { #nested-models }

Each attribute of a Pydantic model has a type.

But that type can itself be another Pydantic model.

So, you can declare deeply nested JSON "objects" with specific attribute names, types and validations.

All that, arbitrarily nested.

### Define a submodel { #define-a-submodel }

For example, we can define an `Image` model:

            return true;
        } else if (other instanceof ToolchainModel that) {
            return java.util.Objects.equals(this.getType(), that.getType())
                && java.util.Objects.equals(this.getProvides(), that.getProvides());
        } else {
            return false;
        }
    } //-- boolean equals(Object)
                ]]>
