Class StandardTypeLocator

Parallels Spring StandardTypeLocator.

Resolves the names used by T(...), instanceof and new ....

Two behaviours matter and both mirror Spring:

java.lang is imported implicitly, so T(String) and T(java.lang.String) are the same type. An unqualified name that is not found is retried with each registered prefix.
The catalogue of available types is explicit (see java-types.ts). Where Spring consults a class loader, this port has a registry, so a type that is not registered raises TYPE_NOT_FOUND rather than being loaded on demand.

Constructors

constructor

new StandardTypeLocator(prefixes?: readonly string[]): StandardTypeLocator
Parameters
- prefixes: readonly string[] = DEFAULT_PREFIXES
  Package prefixes tried for an unqualified name. Defaults to java.lang, matching Java's implicit import.
Returns StandardTypeLocator

Methods

findType

findType(typeName: string): TypeDescriptor
Find type
Parameters
- typeName: string
Returns TypeDescriptor

Throws
SpelEvaluationException if type is not registered
Implementation of TypeLocator.findType
- Defined in type/standard-type-locator.ts:40

hasType

hasType(name: string): boolean
Check if type is registered
Parameters
- name: string
Returns boolean
Implementation of TypeLocator.hasType
- Defined in type/standard-type-locator.ts:64

register

register(
    name: string,
    constructor: new (...args: unknown[]) => unknown,
    staticMethods?: Record<string, (...args: unknown[]) => unknown>,
    staticFields?: Record<string, unknown>,
): void
Convenience: register a JavaScript constructor as a type. Automatically creates a TypeDescriptor wrapping the constructor.
Parameters
- name: string
- constructor: new (...args: unknown[]) => unknown
- staticMethods: Record<string, (...args: unknown[]) => unknown> = {}
- staticFields: Record<string, unknown> = {}
Returns void

registerImport(prefix: string): void
Add a package prefix for unqualified names, mirroring Spring's registerImport.
Parameters
- prefix: string
Returns void
- Defined in type/standard-type-locator.ts:75

registerType

registerType(name: string, descriptor: TypeDescriptor): void
Register type
Parameters
- name: string
- descriptor: TypeDescriptor
Returns void
