方法详细资料

setReadonly

public void setReadonly(boolean readonly)

clear

public BigByteBuffer clear()

从类复制的说明: Buffer

Clears this buffer. The position is set to zero, the limit is set to the capacity, and the mark is discarded.

Invoke this method before using a sequence of channel-read or put operations to fill this buffer. For example:

 buf.clear();     // Prepare buffer for reading
 in.read(buf);    // Read data

This method does not actually erase the data in the buffer, but it is named as if it did because it will most often be used in situations in which that might as well be the case.

覆盖:

clear 在类中 Buffer<BigByteBuffer>

返回:

This buffer

flip

public BigByteBuffer flip()

从类复制的说明: Buffer

Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.

After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example:

 buf.put(magic);    // Prepend header
 in.read(buf);      // Read data into rest of buffer
 buf.flip();        // Flip buffer
 out.write(buf);    // Write header + data to channel

This method is often used in conjunction with method when transferring data from one place to another.

覆盖:

flip 在类中 Buffer<BigByteBuffer>

返回:

This buffer

rewind

public BigByteBuffer rewind()

从类复制的说明: Buffer

Rewinds this buffer. The position is set to zero and the mark is discarded.

Invoke this method before a sequence of channel-write or get operations, assuming that the limit has already been set appropriately. For example:

 out.write(buf);    // Write remaining data
 buf.rewind();      // Rewind buffer
 buf.get(array);    // Copy data into array

指定者:

rewind 在接口中 Rewindable

覆盖:

rewind 在类中 Buffer<BigByteBuffer>

返回:

This buffer

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<BigByteBuffer>

返回:

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

hasArray

public final 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<BigByteBuffer>

返回:

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

array

public final 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<BigByteBuffer>

返回:

The array that backs this buffer

arrayOffset

public final long 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<BigByteBuffer>

返回:

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