get() [1/2]

static ExtractorFactory ppt4j.factory.ExtractorFactory.get ( String prepatchPath, String postpatchPath, String classPath, String... thirdPartySrcPath )

static

Returns an instance of ExtractorFactory initialized with the provided prepatchPath, postpatchPath, classPath, and thirdPartySrcPath.

Parameters

prepatchPath	the path to the pre-patch files
postpatchPath	the path to the post-patch files
classPath	the class path for the ExtractorFactory
thirdPartySrcPath	additional source paths (optional)

Returns

an instance of ExtractorFactory

get() [2/2]

static ExtractorFactory ppt4j.factory.ExtractorFactory.get ( Vulnerability vuln, DatabaseType type )

static

Retrieves an ExtractorFactory based on the specified Vulnerability and DatabaseType. This method generates necessary paths, checks the VM class path, and initializes the ExtractorFactory.

Parameters

vuln	the Vulnerability object
type	the DatabaseType object

Returns

the ExtractorFactory object

getBytecodeClass()

BytecodeExtractor ppt4j.factory.ExtractorFactory.getBytecodeClass

(

String

className

)

throws IOException

Retrieves the bytecode of a class specified by the given class name. If the bytecode for the class is already cached, it returns the cached instance. If the class is contained within a JAR file, it extracts the bytecode from the JAR file. If the class is not found in the JAR file, it logs a debug message and returns a nil BytecodeExtractor. If the class is not within a JAR file, it extracts the bytecode from the classpath directory. It parses the extracted bytecode, adds any inner classes found within the same directory or JAR file, caches the extracted bytecode, and returns the BytecodeExtractor instance.

Parameters

className

the name of the class for which bytecode needs to be extracted

Returns

the BytecodeExtractor instance containing the bytecode of the specified class

Exceptions

IOException

if an I/O error occurs while attempting to extract bytecode

getPost2Class()

CrossMatcher ppt4j.factory.ExtractorFactory.getPost2Class

(

String

className

)

throws IOException

Retrieves a CrossMatcher object associated with a given class name. If the CrossMatcher object is already cached, it is returned directly. Otherwise, a new CrossMatcher object is created using the class name to retrieve the corresponding Java class and bytecode class. The new CrossMatcher object is then cached for future use.

Parameters

className

the name of the class to retrieve the CrossMatcher object for

Returns

the CrossMatcher object associated with the provided class name

Exceptions

IOException

if an I/O error occurs during the retrieval process

getPostJavaClass()

JavaExtractor ppt4j.factory.ExtractorFactory.getPostJavaClass

(

String

className

)

Returns a JavaExtractor object for the specified class name from the cachedPostExtractors map. If the JavaExtractor object does not exist in the map, a new JavaExtractor object is created using the specified class name and added to the map before returning.

Parameters

className

the name of the Java class to extract

Returns

the JavaExtractor object for the specified class name

getPre2Class()

CrossMatcher ppt4j.factory.ExtractorFactory.getPre2Class

(

String

className

)

throws IOException

Retrieves a CrossMatcher object for the given class name. If the CrossMatcher object for the class name is already cached, it is returned. Otherwise, a new CrossMatcher object is created using the pre-java class and bytecode class of the given class name, and then cached for future use.

Parameters

className

the name of the class

Returns

the CrossMatcher object for the given class name

Exceptions

IOException

if an I/O error occurs

getPreJavaClass()

JavaExtractor ppt4j.factory.ExtractorFactory.getPreJavaClass

(

String

className

)

Retrieves a pre-patch Java class extractor for the specified class name.

Parameters

className

the name of the Java class to extract

Returns

a JavaExtractor object for the specified class name from the pre-patch database
