java - How do I use Realm with generic type? -

i have generic method , retrieve objects using generic type. method:

public static <t extends realmobject & indentifiermodel> void storenewdata() {   ...   t item = realm.where(class<t>) // not compiling (expression not expected)     .equalto("id", data.get(i).getid())     .findfirst(); } 

the above isn't working realm.where(class<t>). how pass in generic type realm?

you have supply generic parameter so:

public static <t extends realmobject & indentifiermodel> void storenewdata(class<t> clazz) {   t item = realm.where(clazz)      .equalto("id", 123)     .findfirst(); } 

class<t> not valid, since that's saying realm.where(class<list<string>>) or realm.where(class<string>). need actual class<t> instance. cannot use t.class either since t not available @ runtime due type-erasure. @ runtime, method needs class<t> instance work properly. since cannot t, have explicitly supply argument of type class<t>.
