Hi everybody, does anybody know why wicket uses FLAGS and bits
operator in Component Class.
for example:
in Component.java
line 650 :private int flags = FLAG_VISIBLE | FLAG_ESCAPE_MODEL_STRINGS
| FLAG_VERSIONED | FLAG_ENABLED |
FLAG_IS_RENDER_ALLOWED | FLAG_VISIBILITY_ALLOWED;
line 3456 : protected final boolean getFlag(final int flag)
{
return (flags & flag) != 0;
}
for those who don't know what & operator do: return 1, if the two
operators are 1, otherwise return 0
Are the because optimization?
i have no experience doing frameworks, can someone with experience tell me why?
Thank You!
NM
