If such space has been reserved, special messages can be used that rapidly position an index directly to the member. Operations to remove members are also much faster.</P><P> The value of MemberSlot specifies the offset in bytes from the start of each member where the space for its position link has been reserved. </P><P> The offset of the position link from the start of a member may be either positive or negative, in the range of -2048 to +2047. The default value of MemberSlot is UnknownOffset (a large negative value), which specifies that no slot for an internal position link is available within each member.</P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN7544"></A><H2>Protocols adopted by MemberSlot</H2><P>None</P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN7547"></A><H2>Methods</H2><P>None</P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN7550"></A><H2>Typedefs</H2><P></P><UL><LI><P>dupmember_t<PRE>struct { void *memberData[2]; id owner; }</PRE></P></LI><LI><P>member_t<PRE>struct memberData { void *memberData[2]; }</PRE></P></LI></UL></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLEWIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="swarm.collections.memberblock.protocol.html">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="set.html">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="swarm.collections.offsets.protocol.html">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">MemberBlock</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="swarm.collections.sgml.reference.html">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Offsets</TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
