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
