: : 我的程式码里面有一段:
: : ==============================
: : %dram_dims = {
: : "rw" => ("WW", "RR", "WR"),
: : "bl" => ("FIXED_01", "UNFIX_01", "UNFIX_08", "UNFIX_16",
: : "UNFIX_32", "UNFIX_64", "FIXED_04", "FIXED_08", "FIXED_16"),
: : "rcb" => ("mode0", "mode1", "mode2", "mode3", "mode4", "mode5",
: : "mode6", "mode7")
: : };
: 应该是
: %dram_dims = (
: "rw" => ["WW", "RR", "WR"],
: "bl" => ["FIXED_01", "UNFIX_01", "UNFIX_08", "UNFIX_16",
: "UNFIX_32", "UNFIX_64", "FIXED_04", "FIXED_08", "FIXED_16"],
: "rcb" => ["mode0", "mode1", "mode2", "mode3", "mode4", "mode5",
: "mode6", "mode7"]
: );
: 你写的出来意义大概是
: %tmp = ( "rw" => "WW" , "RR" => "WR" .... );
: $dram_dims{ \%tmp } = undef;
先谢谢 :)
进一步我想问问 (), [], {}的差别是否如下面所说： (一直弄不太懂)
是否在给array或hash指定值的时候，该用 ()
而在给匿名 array / hash，或是给reference指定值的时候，是用 [] / {} 呢?
或是他们的不同之处不是这样想的 @_@;
还有：array of array, hash of hash, array of hash, hash of array
在perl中是不是只能使用参照来作?
谢谢 m(_ _)m
