I envision your interface as:
interface ColumnFactory {
<K, V> Column<K, V> newColumn(
K name, V value, long timestampMillis);
}
Then you could adapt your current implementation:
bind(ColumnFactory.class)
.toProvider(new Provider<ColumnFactory>(){
@Override public ColumnFactory get() {
return new ColumnFactory() {
@Override public <K, V> Column<K, V>
newColumn(
K name, V value, long timestampMillis) {
return Builder.newColumn(
name, value, timestampMillis);
}
);
}
}});
Nothing to worry about here with generic methods.
