Method Detail

buildClassMetadata

protected void buildClassMetadata(MetadataClass metadataClass,
                                  String className,
                                  boolean isLazy)

Build the class metadata for the class name using ASM to read the class byte codes.

getMetadataClass

public MetadataClass getMetadataClass(String className)

Return the class metadata for the class name.

Specified by:

getMetadataClass in class MetadataFactory

getMetadataClass

public MetadataClass getMetadataClass(String className,
                                      boolean isLazy)

Return the class metadata for the class name.

Specified by:

getMetadataClass in class MetadataFactory

resolveGenericTypes

public void resolveGenericTypes(MetadataClass child,
                                List<String> genericTypes,
                                MetadataClass parent,
                                MetadataDescriptor descriptor)

INTERNAL: This method resolves generic types based on the ASM class metadata. Unless every other factory (e.g. APT mirror factory) respects the generic format as built from ASM this method will not work since it is very tied to it.

Specified by:

resolveGenericTypes in class MetadataFactory
