Struct ejni::List

pub struct List<'a> {
    pub inner: Object<'a>,
    pub class: Class<'a>,
    /* private fields */
}

Wrapper around java.util.List

Fields

inner: Object<'a>

The list itself

class: Class<'a>

The type contained in the List

Implementations

impl<'a> List<'a>

pub fn new(env: &'a JNIEnv<'a>, object: Object<'a>, class: Class<'a>) -> Self

Create a List abstraction from it’s raw components. The caller must guarantee that object implements java.util.List and that class is the correct Class

pub fn arraylist(env: &'a JNIEnv<'a>, v_class: Class<'a>) -> Result<Self>

Create a new java.util.ArrayList

pub fn add(&self, object: &Object<'a>) -> Result<bool>

Appends the specified element to the end of this list (optional operation).

pub fn add_at(&self, object: &Object<'a>, index: i32) -> Result<()>

Inserts the specified element at the specified position in this list (optional operation).

pub fn clear(&self) -> Result<()>

Removes all of the elements from this list (optional operation).

pub fn contains(&self, object: &Object<'a>) -> Result<bool>

Returns true if this list contains the specified element.

pub fn get(&self, index: i32) -> Result<Option<Object<'a>>>

Returns the element at the specified position in this list.

pub fn index_of(&self, object: &Object<'a>) -> Result<i32>

Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.

pub fn is_empty(&self) -> Result<bool>

Returns true if this list contains no elements.

pub fn remove(&self, object: &Object<'a>) -> Result<bool>

Removes the first occurrence of the specified element from this list, if it is present (optional operation).

pub fn remove_at(&self, index: i32) -> Result<Option<Object<'a>>>

Removes the element at the specified position in this list (optional operation).

pub fn set(&self, object: &Object<'a>, index: i32) -> Result<Option<Object<'a>>>

Replaces the element at the specified position in this list with the specified element (optional operation).

pub fn size(&self) -> Result<i32>

Returns the number of elements in this list.

pub fn sublist(&self, from: i32, to: i32) -> Result<List<'a>>

Returns a view of the portion of this list between the specified from index, inclusive, and to index, exclusive.

pub fn iterator(&self) -> Result<Iterator<'a>>

Returns an iterator over the elements in this list in proper sequence.

Trait Implementations

impl<'a> Drop for List<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> From<Object<'a>> for List<'a>

fn from(obj: Object<'a>) -> Self

Converts to this type from the input type.

impl<'a> Into<*mut _jobject> for List<'a>

fn into(self) -> *mut _jobject

Converts this type into the (usually inferred) input type.
