Constructor Details

BcelWeaver

public BcelWeaver(BcelWorld world)

Method Details

addLibraryAspect

public ResolvedType addLibraryAspect(String aspectName)

Add the given aspect to the weaver. The type is resolved to support DOT for static inner classes as well as DOLLAR

Parameters:

aspectName -

Returns:

aspect

addLibraryJarFile

public void addLibraryJarFile(File inFile)
                       throws IOException

Parameters:

inFile - directory containing classes or zip/jar class archive

Throws:

IOException

addDirectoryContents

public List<UnwovenClassFile> addDirectoryContents(File inFile,
 File outDir)
                                            throws IOException

Add any .class files in the directory to the outdir. Anything other than .class files in the directory (or its subdirectories) are considered resources and are also copied.

Throws:

IOException

addJarFile

public List<UnwovenClassFile> addJarFile(File inFile,
 File outDir,
 boolean canBeDirectory)

Adds all class files in the jar

needToReweaveWorld

public boolean needToReweaveWorld()

addClassFile

public ReferenceType addClassFile(UnwovenClassFile classFile,
 boolean fromInpath)

Should be addOrReplace

addClassFile

public UnwovenClassFile addClassFile(File classFile,
 File inPathDir,
 File outDir)
                              throws IOException

Throws:

IOException

deleteClassFile

public void deleteClassFile(String typename)

setIsBatchWeave

public void setIsBatchWeave(boolean b)

prepareForWeave

public void prepareForWeave()

setCustomMungerFactory

public void setCustomMungerFactory(CustomMungerFactory factory)

addManifest

public void addManifest(Manifest newManifest)

getManifest

public Manifest getManifest(boolean shouldCreate)

weave

public Collection<String> weave(File file)
                         throws IOException

Throws:

IOException

allWeavingComplete

public void allWeavingComplete()

prepareToProcessReweavableState

public void prepareToProcessReweavableState()

processReweavableStateIfPresent

public void processReweavableStateIfPresent(String className,
 BcelObjectType classType)

getClassType

public BcelObjectType getClassType(String forClass)

helper method - will return NULL if the underlying delegate is an EclipseSourceType and not a BcelObjectType

addParentTypeMungers

public void addParentTypeMungers(String typeName)

addNormalTypeMungers

public void addNormalTypeMungers(String typeName)

getClassFilesFor

public UnwovenClassFile[] getClassFilesFor(LazyClassGen clazz)

weaveParentTypeMungers

public void weaveParentTypeMungers(ResolvedType onType)

Weaves new parents and annotations onto a type ("declare parents" and "declare @type") Algorithm: 1. First pass, do parents then do annotations. During this pass record: - any parent mungers that don't match but have a non-wild annotation type pattern - any annotation mungers that don't match 2. Multiple subsequent passes which go over the munger lists constructed in the first pass, repeatedly applying them until nothing changes. FIXME asc confirm that algorithm is optimal ??
