      • JarTypeSolver

        public JarTypeSolver​(java.nio.file.Path pathToJar)
              throws java.io.IOException
        Create a JarTypeSolver from a Path.
        Parameters:
        pathToJar - The path where the jar is located.
        Throws:
        java.io.IOException - If an I/O exception occurs while reading the Jar.

      • JarTypeSolver

        public JarTypeSolver​(java.io.File pathToJar)
              throws java.io.IOException
        Create a JarTypeSolver from a File.
        Parameters:
        pathToJar - The file pointing to the jar is located.
        Throws:
        java.io.IOException - If an I/O exception occurs while reading the Jar.

      • JarTypeSolver

        public JarTypeSolver​(java.lang.String pathToJar)
              throws java.io.IOException
        Create a JarTypeSolver from a path in a String format.
        Parameters:
        pathToJar - The path pointing to the jar.
        Throws:
        java.io.IOException - If an I/O exception occurs while reading the Jar.

      • JarTypeSolver

        public JarTypeSolver​(java.io.InputStream jarInputStream)
              throws java.io.IOException
        Create a JarTypeSolver from a InputStream. The content will be dumped into a temporary file to be used in the type solver.
        Parameters:
        jarInputStream - The input stream to be used.
        Throws:
        java.io.IOException - If an I/O exception occurs while creating the temporary file.

      • getJarTypeSolver

        @Deprecated
public static JarTypeSolver getJarTypeSolver​(java.lang.String pathToJar)
                                      throws java.io.IOException
        Deprecated.
        Use of this static method (previously following singleton pattern) is strongly discouraged and will be removed in a future version. For now, it has been modified to return a new instance to prevent the IllegalStateException being thrown (as reported in #2547), allowing it to be called multiple times.
        Throws:
        java.io.IOException

      • convertEntryPathToClassName

        private static java.lang.String convertEntryPathToClassName​(java.lang.String entryPath)
        Convert the entry path into a qualified name. The entries in Jar files follows the format com/github/javaparser/ASTParser$JJCalls.class while in the type solver we need to work with com.github.javaparser.ASTParser.JJCalls.
        Parameters:
        entryPath - The entryPath to be converted.
        Returns:
        The qualified name for the entryPath.

      • convertEntryPathToClassPoolName

        private static java.lang.String convertEntryPathToClassPoolName​(java.lang.String entryPath)
        Convert the entry path into a qualified name to be used in ClassPool. The entries in Jar files follows the format com/github/javaparser/ASTParser$JJCalls.class while in the class pool we need to work with com.github.javaparser.ASTParser$JJCalls.
        Parameters:
        entryPath - The entryPath to be converted.
        Returns:
        The qualified name to be used in the class pool.

      • dumpToTempFile

        private java.io.File dumpToTempFile​(java.io.InputStream inputStream)
                             throws java.io.IOException
        Utility function to dump the input stream into a temporary file. This file will be deleted when the virtual machine terminates.
        Parameters:
        inputStream - The input to be dumped.
        Returns:
        The created file with the dumped information.
        Throws:
        java.io.IOException - If an I/O exception occurs while creating the temporary file.

      • addPathToJar

        private void addPathToJar​(java.lang.String pathToJar)
                   throws java.io.IOException
        Utility method to register a new class path.
        Parameters:
        pathToJar - The path pointing to the jar file.
        Throws:
        java.io.IOException - If an I/O error occurs while reading the JarFile.

      • registerKnownClassesFor

        private void registerKnownClassesFor​(java.lang.String pathToJar)
                              throws java.io.IOException
        Register the list of known classes. When we create a new JarTypeSolver we should store the list of solvable types.
        Parameters:
        pathToJar - The path to the jar file.
        Throws:
        java.io.IOException - If an I/O error occurs while reading the JarFile.

      • getKnownClasses

        public java.util.Set<java.lang.String> getKnownClasses()
        Get the set of classes that can be resolved in the current type solver.
        Returns:
        The set of known classes.
