```
public final class CallsiteHolderExplorable
extends CallsiteHolder
```
A CallsiteHolder whose graph has been copied already and thus can be modified without affecting the original (usually cached) version.

An instance of this class is derived from an InlineableGraph and contains a subset of the information there: just the Invoke nodes from it. Such nodes are candidates for depth-first search of further inlining opportunities (thus the adjective "explorable" given to this class)

InliningData.moveForward()

public Set<ParameterNode> getFixedParams()
```
    Parameters for which the callsite targeting graph() provides "fixed" arguments. That callsite isn't referenced by this instance. Instead, it belongs to the graph of the caller of this CallsiteHolderExplorable
    
    Constant arguments don't contribute to fixed-params: those params have been removed already, see InlineableGraph.
    
    Instead, fixed-params are those receiving freshly instantiated arguments (possibly instantiated several levels up in the call-hierarchy)
  - repOK

```
public ResolvedJavaMethod method()
```
    Description copied from class: CallsiteHolder
    
    Gets the method associated with the graph represented by this object.
    
    Specified by:
    
    method in class CallsiteHolder
  - hasRemainingInvokes
```
public boolean hasRemainingInvokes()
```
    Description copied from class: CallsiteHolder
    
    The stack realized by InliningData grows upon InliningData.moveForward() deciding to explore (depth-first) a callsite of the graph associated to this CallsiteHolder. The list of not-yet-considered callsites is managed by CallsiteHolderExplorable, and this method reports whether any such candidates remain.
