Struct CachedIfaceMethod 

pub struct CachedIfaceMethod { /* private fields */ }

A (pinned interface class, method ID) pair resolved once per process. Declare as static; the embedded OnceLock handles the one-time resolution race (both winners produce equivalent values).

Implementations

impl CachedIfaceMethod

pub const fn new() -> Self

pub fn call_object<'local>( &self, env: &mut JNIEnv<'local>, class_fqn: &str, method: &str, descr: &str, obj: &JObject<'_>, args: &[jvalue], ) -> Result<JObject<'local>, String>

Invoke the interface method on obj, returning its Object result. Resolves (and pins) the interface class on first use.

SAFETY contract carried for the caller: obj must implement the interface named by class_fqn, and descr must be the method’s exact JVM descriptor — both are generated from the same plan, so they agree by construction.

Trait Implementations

impl Default for CachedIfaceMethod

fn default() -> Self

Returns the “default value” for a type.
