Method Detail

content

public ByteBuf content()

Description copied from interface: ByteBufHolder

Return the data which is held by this ByteBufHolder.

Specified by:

content in interface ByteBufHolder

copy

public ByteBufHolder copy()

Creates a deep copy of this ByteBufHolder.

This method calls replace(content().copy()) by default.

Specified by:

copy in interface ByteBufHolder

duplicate

public ByteBufHolder duplicate()

Duplicates this ByteBufHolder. Be aware that this will not automatically call ByteBufHolder.retain().

This method calls replace(content().duplicate()) by default.

Specified by:

duplicate in interface ByteBufHolder

retainedDuplicate

public ByteBufHolder retainedDuplicate()

Duplicates this ByteBufHolder. This method returns a retained duplicate unlike ByteBufHolder.duplicate().

This method calls replace(content().retainedDuplicate()) by default.

Specified by:

retainedDuplicate in interface ByteBufHolder

See Also:

ByteBuf.retainedDuplicate()

replace

public ByteBufHolder replace(ByteBuf content)

Returns a new ByteBufHolder which contains the specified content.

Override this method to return a new instance of this object whose content is set to the specified content. The default implementation of copy(), duplicate() and retainedDuplicate() invokes this method to create a copy.

Specified by:

replace in interface ByteBufHolder

refCnt

public int refCnt()

Specified by:

refCnt in interface io.netty.util.ReferenceCounted

retain

public ByteBufHolder retain()

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface io.netty.util.ReferenceCounted

retain

public ByteBufHolder retain(int increment)

Specified by:

retain in interface ByteBufHolder

Specified by:

retain in interface io.netty.util.ReferenceCounted

touch

public ByteBufHolder touch()

Specified by:

touch in interface ByteBufHolder

Specified by:

touch in interface io.netty.util.ReferenceCounted

touch

public ByteBufHolder touch(Object hint)

Specified by:

touch in interface ByteBufHolder

Specified by:

touch in interface io.netty.util.ReferenceCounted

release

public boolean release()

Specified by:

release in interface io.netty.util.ReferenceCounted

release

public boolean release(int decrement)

Specified by:

release in interface io.netty.util.ReferenceCounted

contentToString

protected final String contentToString()

Return ByteBuf.toString() without checking the reference count first. This is useful to implement toString().
