Tao Jie created MNEMONIC-464: -------------------------------- Summary: Support normal java object field in durable type Key: MNEMONIC-464 URL: https://issues.apache.org/jira/browse/MNEMONIC-464 Project: Mnemonic Issue Type: New Feature Affects Versions: 0.11.0 Reporter: Tao Jie Assignee: Tao Jie
Today, we define a durable type(eg: DurableA), we may define a normal object field(B b). When we restore a DurableA object a(eg: we put a into a DurableHashMap and get it from the map later), its reference of b would lost. As discussed with [~qichfan] offline, one solution is that we maintain a Map<B_ID, B> to keep the reference of B and have a B_ID(long type) field in DurableA. Then we can find the object b from restored object A. We can do this in the Mnemonic framework, and add a new type (maybe DurableReference?) to support this situation. like: {code} class DurableA { @DurableGetter public abstract DurableReference<B> getFieldB(); @DurableSetter public abstract void setFieldB(DurableReference<B> b, boolean destroy) } {code} Then we can get object b by {code} a.getFieldB().get() {code} Any thought? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
