Struct JExceptionInInitializerError 

pub struct JExceptionInInitializerError<'local>(/* private fields */);

A java.lang.ExceptionInInitializerError reference, tied to a JNI local reference frame.

See the JObject documentation for more information about object references, how to cast them, and local reference frame lifetimes.

Implementations

impl<'local> JExceptionInInitializerError<'local>

pub unsafe fn from_raw<'env_inner>( env: &Env<'env_inner>, raw: jobject, ) -> JExceptionInInitializerError<'env_inner>

Creates a JExceptionInInitializerError that wraps the given raw jobject

Safety

• raw must be a valid raw JNI local reference (or null).
• raw must be an instance of the correct Java class.
• There must not be any other owning Reference wrapper for the same reference.
• The local reference must belong to the current thread and not outlive the JNI stack frame associated with the Env 'local lifetime.

pub const fn null() -> JExceptionInInitializerError<'static>

Creates a new null reference.

Null references are always valid and do not belong to a local reference frame. Therefore, the returned JExceptionInInitializerError always has the 'static lifetime.

pub fn into_raw(self) -> jobject

Unwrap to the raw jni type.

pub fn cast_local<'any_local>( env: &mut Env<'_>, obj: impl Reference + Into<JObject<'any_local>> + AsRef<JObject<'any_local>>, ) -> Result<JExceptionInInitializerError<'any_local>>

Cast a local reference to a JExceptionInInitializerError

This will do a runtime (IsInstanceOf) check that the object is an instance of the correct class.

Also see these other options for casting local or global references to a JExceptionInInitializerError:

• Env::as_cast
• Env::new_cast_local_ref
• Env::cast_local
• Env::new_cast_global_ref
• Env::cast_global

Errors

Returns Error::WrongObjectType if the IsInstanceOf check fails.

impl<'local> JExceptionInInitializerError<'local>

pub fn as_throwable(&self) -> Cast<'local, '_, JThrowable<'local>>

Casts this JExceptionInInitializerError to a ::jni::objects::JThrowable

This does not require a runtime type check since any JExceptionInInitializerError is also a ::jni::objects::JThrowable

impl JExceptionInInitializerError<'static>

pub fn new_null<'env_local>( env: &mut Env<'env_local>, ) -> Result<JExceptionInInitializerError<'env_local>>

Construct without any message

pub fn new<'env_local, 'local_0>( env: &mut Env<'env_local>, msg: impl AsRef<JString<'local_0>>, ) -> Result<JExceptionInInitializerError<'env_local>>

Construct with a message

pub fn new_with_exception<'env_local, 'local_0>( env: &mut Env<'env_local>, cause: impl AsRef<JThrowable<'local_0>>, ) -> Result<JExceptionInInitializerError<'env_local>>

Construct with only an exception cause and a null message

impl<'local> JExceptionInInitializerError<'local>

pub fn get_cause<'env_local>( &self, env: &mut Env<'env_local>, ) -> Result<JThrowable<'env_local>>

Returns the exception that was thrown during static initialization.

pub fn get_exception<'env_local>( &self, env: &mut Env<'env_local>, ) -> Result<JThrowable<'env_local>>

Returns the exception that was thrown during static initialization.

impl<'local> JExceptionInInitializerError<'local>

pub fn matches<'any, 'from>( env: &Env<'_>, throwable: &'from JThrowable<'any>, ) -> Result<Option<Cast<'any, 'from, JExceptionInInitializerError<'any>>>>

Checks if the given throwable is an instance of this exception type.

Returns Some(Cast<JExceptionInInitializerError>) if the throwable is an instance of this exception type or returns None if it is not.

Returns Error::NullPtr if the throwable is null.

Methods from Deref<Target = JObject<'local>>

pub fn as_raw(&self) -> jobject

Returns the raw JNI pointer.

impl<'local> Deref for JExceptionInInitializerError<'local>

type Target = JObject<'local>

The resulting type after dereferencing.

impl<'local> Reference for JExceptionInInitializerError<'local>

type Kind<'env> = JExceptionInInitializerError<'env>

The generic associated Self::Kind type corresponds to the underlying class type (such as JObject or JString), parameterized by the lifetime that indicates whether the type holds a global reference ('static) or a local reference that’s tied to a JNI stack frame.

type GlobalKind = JExceptionInInitializerError<'static>

The associated GlobalKind type should be equivalent to Kind<'static>, with the additional bound that ensures the type is Send + Sync

fn as_raw(&self) -> jobject

Returns the underlying, raw crate::sys::jobject reference.

fn class_name() -> Cow<'static, JNIStr>

The fully qualified class name of the Java class represented by this reference.

fn lookup_class<'caller>( env: &Env<'_>, loader_context: &LoaderContext<'_, '_>, ) -> Result<impl Deref<Target = Global<JClass<'static>>> + 'caller>

Looks up a global reference to the JClass associated with this reference.

unsafe fn kind_from_raw<'env>(local_ref: jobject) -> Self::Kind<'env>

Returns a new reference type based on Self::Kind for the given reference that is tied to the specified lifetime.

unsafe fn global_kind_from_raw(global_ref: jobject) -> Self::GlobalKind

Returns a ('static) reference type based on Self::GlobalKind for the given global_ref.

fn is_null(&self) -> bool

Returns true if this is a null object reference

fn null<'any>() -> Self::Kind<'any>

Returns null reference based on Self::Kind
