How do i convert String type to an BinaryEntry Type ?

Question

We have to differentiate between keys that come to Erase method of custom publisher. So, we appended "|" at the end of the key as below
key = "a"; //Actual key that is in Cache
if(//some condition)
newKey = "a|"; //newKey to differntiate
getCache().remove(newKey);
else
getCache().remove(key);
Now, the call comes to Erase method of our custom publisher. Here, we need to perform different operation for the key which has "|" in it. So, we added below code in custom Erase method.
public void erase(BinaryEntry binEntry)
String key = (String) binEntry.getKey();
if(key.contains("|"))
//Need to perform some DB operation here. Then,
//now the key is "a|". we need to remove the "|" symbol and call erase method to remove the actual key ("a") from cache. So we added below code
String newKey = (dnsDomainName).replace("|", "");
//Here the problem is, key is of type String. But, Erase method can take only BinaryEntry type. So, we tried this
binEntry = (BinaryEntry)(binEntry.getContext().getKeyToInternalConverter().convert(key));
super.erase(binEntry); //but it dint work. The entry is not getting deleted from Cache.
//How do we convert the key that is of String type to BinaryEntry ?
else
super.erase(binEntry);
Can someone suggest ?

Can someone suggest ?Excuse me, but you write here totally does not make sense on its own.
1. What class is this method on?
2. Why do you want to use a key in the place of an entry?
If I correctly interpret what you try to achieve, your super-class implementation has to know how to deal with the trailing pipe character as you are never supposed to change the key on an entry, and the entry without the pipe does not exist either.
