Method Detail

getMethodDescriptor

public static MethodDescriptor getMethodDescriptor(org.apache.bcel.classfile.JavaClass jclass,
                                                   org.apache.bcel.classfile.Method method)

Construct a MethodDescriptor from JavaClass and method.

Parameters:

jclass - a JavaClass

method - a Method belonging to the JavaClass

Returns:

a MethodDescriptor identifying the method

getCalledMethodDescriptor

public static MethodDescriptor getCalledMethodDescriptor(org.apache.bcel.generic.InvokeInstruction inv,
                                                         org.apache.bcel.generic.ConstantPoolGen cpg)

Get a MethodDescriptor describing the method called by given InvokeInstruction.

Parameters:

inv - the InvokeInstruction

cpg - ConstantPoolGen of class containing instruction

Returns:

MethodDescriptor describing the called method

getAccessedFieldDescriptor

public static FieldDescriptor getAccessedFieldDescriptor(org.apache.bcel.generic.FieldInstruction fins,
                                                         org.apache.bcel.generic.ConstantPoolGen cpg)

Get FieldDescriptor describing the field accessed by given FieldInstruction.

Parameters:

fins - a FieldInstruction

cpg - ConstantPoolGen for the method containing the FieldInstruction

Returns:

FieldDescriptor describing the field accessed by given FieldInstruction

getClassDescriptor

public static ClassDescriptor getClassDescriptor(org.apache.bcel.classfile.JavaClass jclass)

Construct a ClassDescriptor from a JavaClass.

Parameters:

jclass - a JavaClass

Returns:

a ClassDescriptor identifying that JavaClass

preTiger

public static boolean preTiger(org.apache.bcel.classfile.JavaClass jclass)

Checks if classfile was compiled for pre 1.5 target

getClassDescriptor

public static ClassDescriptor getClassDescriptor(org.apache.bcel.generic.ObjectType type)

Deprecated.

Use DescriptorFactory.getClassDescriptor(ObjectType) instead

Get a ClassDescriptor for the class described by given ObjectType object.

Parameters:

type - an ObjectType

Returns:

a ClassDescriptor for the class described by the ObjectType

throwClassNotFoundException

public static void throwClassNotFoundException(ClassDescriptor classDescriptor)
                                        throws java.lang.ClassNotFoundException

Deprecated.

Use ClassDescriptor.throwClassNotFoundException(ClassDescriptor) instead

Throw a ClassNotFoundException to indicate that class named by given ClassDescriptor cannot be found. The exception message is formatted in a way that can be decoded by ClassNotFoundExceptionParser.

Parameters:

classDescriptor - ClassDescriptor naming a class that cannot be found

Throws:

java.lang.ClassNotFoundException
