Download the PHP package openapi-tools/registry without Composer

registry

Class registries for OpenAPI Tools code generators. Maps cebe/php-openapi schema objects to stable PHP class names while gathering an OpenAPI spec, tracks inline contract shapes, and records schemas used as error responses.

Installation

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

Components

Usage

These registries are created and passed through the gathering pipeline in openapi-tools/gatherer. The examples below show how each registry behaves on its own.

Schema registry

The schema registry maps OpenAPI schema objects to PHP class names. Pre-register component schemas with addClassName() before resolving references so naming stays consistent across the spec.

Array schemas are unwrapped to their items schema before lookup. When the same PHP object is passed again, the cached class name is returned regardless of the fallback name.

Unknown schemas

Schemas resolved via get() that were not pre-registered are collected and can be drained for a second gathering pass. This is how Gatherer discovers nested schemas referenced during property and operation gathering:

Each call to unknownSchemas() yields the current batch and clears the internal queue.

Duplicates and aliases

When allowDuplicatedSchemas is true and useAliasesForDuplication is true, a schema with the same JSON structure as an existing one still receives a new class name, and the duplicate is recorded as an alias:

When duplicates are allowed but aliases are disabled, each occurrence gets its own class name with no alias mapping.

When the fallback name is already taken by another unknown schema, the registry appends an incrementing suffix (Foo, FooB, FooC, …).

Contract registry

The contract registry assigns class names to inline object schemas used as contracts (nested shapes embedded in a parent schema). It does not deduplicate by JSON content—only by object identity and fallback name collision:

Like unknownSchemas() on the schema registry, contracts() drains and clears the internal queue.

Throwable schema registry

Operations that return error status codes register their response schema class names so generators can treat them as throwables:
