|---|---|
ByteBuf |
asReadOnly()
Returns a read-only version of this buffer.
|
ByteBuf |

ByteBuf |
order(java.nio.ByteOrder endianness)
Returns a buffer with the specified
endianness which shares the whole region,
indexes, and marks of this buffer. |
ByteBuf |
readRetainedSlice(int length)
Returns a new retained slice of this buffer's sub-region starting at the current
readerIndex and increases the readerIndex by the size
of the new slice (= length). |
ByteBuf |
readSlice(int length)
Returns a new slice of this buffer's sub-region starting at the current
readerIndex and increases the readerIndex by the size
of the new slice (= length). |

release()
Decreases the reference count by
1 and deallocates this object if the reference count reaches at
0. |
boolean |
release(int decrement)
Decreases the reference count by the specified
decrement and deallocates this object if the reference
count reaches at 0. |

Increases the reference count by
1. |
ByteBuf |
retain(int increment)
Increases the reference count by the specified
increment. |

Returns a retained slice of this buffer's readable bytes.
|
ByteBuf |
retainedSlice(int index,
int length)
Returns a retained slice of this buffer's sub-region.

UnreleasableByteBuf(ByteBuf buf)
public ByteBuf order(java.nio.ByteOrder endianness)
ByteBufendianness which shares the whole region,
indexes, and marks of this buffer. Modifying the content, the indexes, or the marks of the
returned buffer or this buffer affects each other's content, indexes, and marks. If the
specified endianness is identical to this buffer's byte order, this method can
return this. This method does not modify readerIndex or writerIndex
of this buffer.order in class WrappedByteBufpublic ByteBuf asReadOnly()
ByteBufasReadOnly in class WrappedByteBufpublic ByteBuf readSlice(int length)
ByteBufreaderIndex and increases the readerIndex by the size
of the new slice (= length).
Also be aware that this method will NOT call ByteBuf.retain() and so the
reference count will NOT be increased.
readSlice in class WrappedByteBuflength - the size of the new slicepublic ByteBuf readRetainedSlice(int length)
ByteBufreaderIndex and increases the readerIndex by the size
of the new slice (= length).
Note that this method returns a retained buffer unlike ByteBuf.readSlice(int).
This method behaves similarly to readSlice(...).retain() except that this method may return
a buffer implementation that produces less garbage.
readRetainedSlice in class WrappedByteBuflength - the size of the new slicepublic ByteBuf slice()
ByteBufbuf.slice(buf.readerIndex(), buf.readableBytes()).
This method does not modify readerIndex or writerIndex of
this buffer.
Also be aware that this method will NOT call ByteBuf.retain() and so the
reference count will NOT be increased.
slice in class WrappedByteBufpublic ByteBuf retainedSlice()
ByteBufbuf.slice(buf.readerIndex(), buf.readableBytes()).
This method does not modify readerIndex or writerIndex of
this buffer.
Note that this method returns a retained buffer unlike ByteBuf.slice().
This method behaves similarly to slice().retain() except that this method may return
a buffer implementation that produces less garbage.
retainedSlice in class WrappedByteBufpublic ByteBuf slice(int index, int length)
ByteBufreaderIndex or writerIndex of
this buffer.
Also be aware that this method will NOT call ByteBuf.retain() and so the
reference count will NOT be increased.
slice in class WrappedByteBufpublic ByteBuf retainedSlice(int index, int length)
ByteBufreaderIndex or writerIndex of
this buffer.
Note that this method returns a retained buffer unlike ByteBuf.slice(int, int).
This method behaves similarly to slice(...).retain() except that this method may return
a buffer implementation that produces less garbage.
retainedSlice in class WrappedByteBufpublic ByteBuf duplicate()
ByteBufreaderIndex or writerIndex of
this buffer.
The reader and writer marks will not be duplicated. Also be aware that this method will
NOT call ByteBuf.retain() and so the reference count will NOT be increased.
duplicate in class WrappedByteBufByteBuf.slice().
However this buffer will share the capacity of the underlying buffer, and therefore allows access to all of the
underlying content if necessary.public ByteBuf retainedDuplicate()
ByteBufbuf.slice(0, buf.capacity()).
This method does not modify readerIndex or writerIndex of
this buffer.
Note that this method returns a retained buffer unlike ByteBuf.slice(int, int).
This method behaves similarly to duplicate().retain() except that this method may return
a buffer implementation that produces less garbage.
