Enum jni::objects::JValue

pub enum JValue<'a> {
    Object(JObject<'a>),
    Byte(jbyte),
    Char(jchar),
    Short(jshort),
    Int(jint),
    Long(jlong),
    Bool(jboolean),
    Float(jfloat),
    Double(jdouble),
    Void,
}

Rusty version of the JNI C jvalue enum. Used in Java method call arguments and returns.

Variants

Object(JObject<'a>)Byte(jbyte)Char(jchar)Short(jshort)Int(jint)Long(jlong)Bool(jboolean)Float(jfloat)Double(jdouble)Void

Methods

impl<'a> JValue<'a>

fn to_jni(self) -> jvalue

Convert the enum to its jni-compatible equivalent.

fn type_name(&self) -> &'static str

Get the type name for the enum variant.

fn primitive_type(&self) -> Option<Primitive>

Get the primitive type for the enum variant. If it's not a primitive (i.e. an Object), returns None.

fn l(self) -> Result<JObject<'a>>

Try to unwrap to an Object.

fn z(self) -> Result<bool>

Try to unwrap to a boolean.

fn b(self) -> Result<jbyte>

Try to unwrap to a byte.

fn c(self) -> Result<jchar>

Try to unwrap to a char.

fn d(self) -> Result<jdouble>

Try to unwrap to a double.

fn f(self) -> Result<jfloat>

Try to unwrap to a float.

fn i(self) -> Result<jint>

Try to unwrap to an int.

fn j(self) -> Result<jlong>

Try to unwrap to a long.

fn s(self) -> Result<jshort>

Try to unwrap to a short.

fn v(self) -> Result<()>

Try to unwrap to a void.
