pack-priv Class ReadOnlyHeapBuffer

Overrides org.glassfish.grizzly.memory.HeapBuffer.asReadOnlyBuffer.

Implements org.glassfish.grizzly.Buffer.asReadOnlyBuffer.

Doc from org.glassfish.grizzly.Buffer.asReadOnlyBuffer.

Creates a new, read-only Buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffer's position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.

If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.

Doc from org.glassfish.grizzly.Buffer.put.

Relative bulk put method  (optional operation).

This method transfers the bytes remaining in the given source buffer into this buffer. If there are more bytes remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.

Otherwise, this method copies n = src.remaining() bytes from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.

In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop

while (src.hasRemaining())
    dst.put(src.get());

Doc from org.glassfish.grizzly.Buffer.put.

Relative bulk put method  (optional operation).

This method transfers the "length" bytes from the given source buffer into this buffer. If this buffer has less bytes remaining than length, that is, if length > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.

Otherwise, this method copies n = length bytes from the given position in the source buffer into this buffer, starting from the current buffer position. The positions of this buffer is then incremented by length.

In other words, an invocation of this method of the form dst.put(src, position, length) has exactly the same effect as the loop

for (int i = 0; i < length; i++)
    dst.put(src.get(i + position));

Doc from org.glassfish.grizzly.Buffer.put.

Relative bulk put method  (optional operation).

This method transfers bytes into this buffer from the given source array. If there are more bytes to be copied from the array than remain in this buffer, that is, if length > remaining(), then no bytes are transferred and a BufferOverflowException is thrown.

Otherwise, this method copies length bytes from the given array into this buffer, starting at the given offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.

In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop

Doc from org.glassfish.grizzly.memory.HeapBuffer.toByteBuffer.

Converts this Buffer to a ByteBuffer. If this Buffer is not composite - then returned ByteBuffer's content is a shared subsequence of this buffer's content, with CompositeBuffer this is not guaranteed. The position of the returned ByteBuffer is not guaranteed to be 0, the capacity of the returned ByteBuffer is not guaranteed to be equal to the capacity of this Buffer. It is guaranteed that the result of the returned ByteBuffer's ByteBuffer#remaining() call will be equal to this Buffer's remaining() call. The Buffer's and ByteBuffer's position, limit, and mark values are not guaranteed to be independent, so it's recommended to save and restore position, limit values if it is planned to change them or ByteBuffer#slice() the returned ByteBuffer.
