Direct Known Subclasses:

PersistentBloatContext

public abstract class BloatContext
extends java.lang.Object
implements EDU.purdue.cs.bloat.inline.InlineContext

This abstract class is a central repository for all things that are necessary for a BLOATing sessions. Its subclasses implement certain schemes for managing BLOAT data structures such as editors and control flow graphs.

Constructor Detail

BloatContext

public BloatContext(ClassInfoLoader loader)

Constructor. Each BloatContext needs to know about a ClassInfoLoader.

Method Detail

db

protected static void db(java.lang.String s)

isSystem

public static boolean isSystem(Type type)

Returns true if the give type is a system class (that is, has the same class loader as java.lang.String).

setRootMethods

public void setRootMethods(java.util.Set roots)

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext

Sets the root methods for this InlineContext.

Specified by:

setRootMethods in interface EDU.purdue.cs.bloat.inline.InlineContext

Parameters:

roots - The root methods (MemberRefs) of the program

getCallGraph

public EDU.purdue.cs.bloat.inline.CallGraph getCallGraph()

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext

Returns the call graph for the program.

Specified by:

getCallGraph in interface EDU.purdue.cs.bloat.inline.InlineContext

getInlineStats

public EDU.purdue.cs.bloat.inline.InlineStats getInlineStats()

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext

Returns an InlineStats object for getting statistics about inlining.

Specified by:

getInlineStats in interface EDU.purdue.cs.bloat.inline.InlineContext

addIgnorePackage

public void addIgnorePackage(java.lang.String name)

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext

Notes that all classes, methods, and fields in a package should be "ignored" by inlining. That is, methods won't be inlined, classes won't be involved in specialization, etc. Note that it is exceptable to just add a prefix of a package name. For instance, adding "java" will ignore java.lang.Object, java.io.File, etc.

Specified by:

addIgnorePackage in interface EDU.purdue.cs.bloat.inline.InlineContext

addIgnoreClass

public void addIgnoreClass(Type type)

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext

Notes that a class should be ignored by inlining. That is, none of its methods will be inlined and it won't be involved in specialization.

Specified by:

addIgnoreClass in interface EDU.purdue.cs.bloat.inline.InlineContext

addIgnoreMethod

public void addIgnoreMethod(MemberRef method)

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext

Notes that a method should be ignored by inlining. That is, it will not be inlined.

Specified by:

addIgnoreMethod in interface EDU.purdue.cs.bloat.inline.InlineContext

addIgnoreField

public void addIgnoreField(MemberRef field)

Description copied from interface: EDU.purdue.cs.bloat.inline.InlineContext
