Class IntersectionCastSupport

java.lang.Object

org.codehaus.groovy.runtime.IntersectionCastSupport

public final class IntersectionCastSupport
extends Object

Runtime support for intersection-type cast and as coercion (GROOVY-11998). Compiler-generated bytecode for (A & B) value and value as (A & B) routes through these helpers when the target is an intersection type and the source is not a native lambda or method reference (those cases are handled at compile time via LambdaMetafactory.altMetafactory markers).

Since:

6.0.0

Method Summary

Modifier and Type	Method	Description
static Object	asType(Object source, Class<?>[] components)	Coercion: produce an object that satisfies every component.
static Object	castTo(Object source, Class<?>[] components)	Strict cast: every component must already be assignment-compatible with the source's runtime class.

Method Details

castTo

public static Object castTo(Object source,
 Class<?>[] components)

Strict cast: every component must already be assignment-compatible with the source's runtime class. Throws GroovyCastException otherwise.

asType

public static Object asType(Object source,
 Class<?>[] components)

Coercion: produce an object that satisfies every component. For Closure and Map sources, a multi-interface proxy is built via ProxyGenerator. For other sources, falls back to castTo(java.lang.Object, java.lang.Class<?>[]) so the behaviour is at least as strict as a cast.
