Constructor Detail

IRModuleBody

public IRModuleBody(IRManager manager,
                    IRScope lexicalParent,
                    ByteList name,
                    int lineNumber,
                    StaticScope staticScope,
                    boolean executesOnce)

Method Detail

getNearestModuleReferencingScopeDepth

public int getNearestModuleReferencingScopeDepth()

Description copied from class: IRScope

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.

Overrides:

getNearestModuleReferencingScopeDepth in class IRScope

getScopeType

public IRScopeType getScopeType()

Specified by:

getScopeType in class IRScope

isModuleBody

public boolean isModuleBody()

Description copied from class: IRScope

Does this scope represent a module body?

Overrides:

isModuleBody in class IRScope

cleanupAfterExecution

public void cleanupAfterExecution()

Description copied from class: IRScope

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:

cleanupAfterExecution in class IRScope

executesOnce

public boolean executesOnce()

Overrides:

executesOnce in class IRScope
