ArrayBuffer

public ArrayBuffer(E[] buf)

ArrayBuffer

public ArrayBuffer(E[] buf,
                   int offset)

ArrayBuffer

public ArrayBuffer(E[] buf,
                   int offset,
                   int length)

把指定的数组 包装为 ArrayBuffer，从 offset开始，包装长度为 length

参数:

buf -

ArrayBuffer

public ArrayBuffer(int mark,
                   int pos,
                   int lim,
                   int cap,

                   int offset)

方法详细资料

isReadOnly

public boolean isReadOnly()

从类复制的说明: Buffer

Tells whether or not this buffer is read-only.

指定者:

isReadOnly 在类中 Buffer<E,ArrayBuffer<E>>

返回:

true if, and only if, this buffer is read-only

hasArray

public boolean hasArray()

从类复制的说明: Buffer

Tells whether or not this buffer is backed by an accessible array.

If this method returns true then the array and arrayOffset methods may safely be invoked.

指定者:

hasArray 在类中 Buffer<E,ArrayBuffer<E>>

返回:

true if, and only if, this buffer is backed by an array and is not read-only

array

public Object array()

从类复制的说明: Buffer

Returns the array that backs this buffer (optional operation).

This method is intended to allow array-backed buffers to be passed to native code more efficiently. Concrete subclasses provide more strongly-typed return values for this method.

Modifications to this buffer's content will cause the returned array's content to be modified, and vice versa.

Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.

指定者:

array 在类中 Buffer<E,ArrayBuffer<E>>

返回:

The array that backs this buffer

arrayOffset

public int arrayOffset()

从类复制的说明: Buffer

Returns the offset within this buffer's backing array of the first element of the buffer (optional operation).

If this buffer is backed by an array then buffer position p corresponds to array index p + arrayOffset().

Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.

指定者:

arrayOffset 在类中 Buffer<E,ArrayBuffer<E>>

返回:

The offset within this buffer's array of the first element of the buffer

put

public ArrayBuffer<E> put(@Nullable
                          E e)

指定者:

put 在类中 Buffer<E,ArrayBuffer<E>>

返回:

put

public ArrayBuffer<E> put(int index,
                          @Nullable
                          E e)

指定者:

put 在类中 Buffer<E,ArrayBuffer<E>>

返回:

get

public E get()

指定者:

get 在类中 Buffer<E,ArrayBuffer<E>>

返回:

get

public E get(int index)

get

public List<E> get(int index,
                   int maxlength)

指定者:

get 在类中 Buffer<E,ArrayBuffer<E>>

参数:

index - 起始位置

maxlength - 最多获取数量，如果小于0 ，则从指定位置到limit

返回:
