Trait toad_jni::java::Type

pub trait Type: TypeSealed {
    const SIG: Signature;

    // Required method
    fn jni() -> JavaType;

    // Provided method
    fn is_type_of(e: &mut Env<'_>, o: &JObject<'_>) -> bool { ... }
}

A type that has a corresponding Java type

Sealed

You can’t implement this trait directly; instead you can define new java::Classes, which will then come with Type implementations for free.

Conversions

rust type	java type	notes
T where T: java::Class	fully qualified class path
Result<T, java::lang::Throwable>	T::PATH	java::Class must be implemented for T
java::Nullable<T>	T::PATH	java::Class must be implemented for T
java::NoUpcast<T>	java::lang::Object	java::Class must be implemented for T. Used when a method should have the signature of returning T, but you would like the object reference without java::Object::upcasting.
java::lang::Object	java.lang.Object
Vec<T>	T[]	T must be java::Type
String	java.lang.String	java::Class and java::Object implemented for String
()	void
u16	char
i8	byte
i16	short
i32	int
i64	long
f32	float
f64	double
fn(T,*) -> R	corresponding java type signature	all argument types and return types must be java::Type

Required Associated Constants

const SIG: Signature

The signature for this type

Required Methods

fn jni() -> JavaType

Get the jni rep of this type

Provided Methods

fn is_type_of(e: &mut Env<'_>, o: &JObject<'_>) -> bool

Determines whether an object is an instance of this type
