cleanupAfterExecution()

Overrides org.jruby.ir.IRScope.cleanupAfterExecution.

We are done with execution of this scope and we can cleanup some amount of things in this scope which will no longer be used.

public boolean
executesOnce()

Overrides org.jruby.ir.IRScope.executesOnce.

public int
getNearestModuleReferencingScopeDepth()

Overrides org.jruby.ir.IRScope.getNearestModuleReferencingScopeDepth.

Returns the nearest scope which we can extract a live module from.

public IRScopeType
getScopeType()

Implements abstract org.jruby.ir.IRScope.getScopeType.

public boolean
isModuleBody()

Overrides org.jruby.ir.IRScope.isModuleBody.

Does this scope represent a module body?

public void cleanupAfterExecution()

Overrides org.jruby.ir.IRScope.cleanupAfterExecution.

Doc from org.jruby.ir.IRScope.cleanupAfterExecution.

We are done with execution of this scope and we can cleanup some amount of things in this scope which will no longer be used. Sub-classes will be the deciders of what is no longer needed. An example, to illustrate the complexity of cleanup: A class with no nested closures can remove any ICs created and can remove some other infomrational data structures like allocated variables unless closures do exist and then the ICs must stay for when closures JIT.

Overrides org.jruby.ir.IRScope.getNearestModuleReferencingScopeDepth.

Doc from org.jruby.ir.IRScope.getNearestModuleReferencingScopeDepth.

Returns the nearest scope which we can extract a live module from. If this returns null (like for evals), then it means it cannot be statically determined.
