findOwner	back to summary
pack-priv JSRInlinerAdapter.Instantiation findOwner(final int insnIndex) Returns the "owner" of a particular instruction relative to this instantiation: the owner refers to the Instantiation which will emit the version of this instruction that we will execute. Typically, the return value is either `this` or `null`. `this` indicates that this instantiation will generate the version of this instruction that we will execute, and `null` indicates that this instantiation never executes the given instruction. Sometimes, however, an instruction can belong to multiple subroutines; this is called a shared instruction, and occurs when multiple subroutines branch to common points of control. In this case, the owner is the oldest instantiation which owns the instruction in question (parent instantiations are older than their children). Parameters insnIndex:int the index of an instruction in the original code. Returns:JSRInlinerAdapter.Instantiation the "owner" of a particular instruction relative to this instantiation.

More formally, if this map contains a mapping from a key `k` to a value `v` such that `Objects.equals(key, k)`, then this method returns `v`; otherwise it returns `null`. (There can be at most one such mapping.) If this map permits null values, then a return value of `null` does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to `null`. The `containsKey` operation may be used to distinguish these two cases.
