Method Detail

make

public static TypeData[] make(int size)

getTypeTag

public abstract int getTypeTag()

getTypeData

public abstract int getTypeData(ConstPool cp)

join

public TypeData join()

isBasicType

public abstract TypeData.BasicType isBasicType()

If the type is a basic type, this method normalizes the type and returns a BasicType object. Otherwise, it returns null.

is2WordType

public abstract boolean is2WordType()

isNullType

public boolean isNullType()

Returns false if getName() returns a valid type name.

isUninit

public boolean isUninit()

eq

public abstract boolean eq(TypeData d)

getName

public abstract String getName()

setType

public abstract void setType(String s,
                             ClassPool cp)
                      throws BadBytecode

Throws:

BadBytecode

getArrayType

public abstract TypeData getArrayType(int dim)
                               throws NotFoundException

Parameters:

dim - array dimension. It may be negative.

Throws:

NotFoundException

dfs

public int dfs(List<TypeData> order,
               int index,
               ClassPool cp)
        throws NotFoundException

Depth-first search by Tarjan's algorithm

Parameters:

order - a node stack in the order in which nodes are visited.

index - the index used by the algorithm.

Throws:

NotFoundException

toTypeVar

protected TypeData.TypeVar toTypeVar(int dim)

Returns this if it is a TypeVar or a TypeVar that this type depends on. Otherwise, this method returns null. It is used by dfs().

Parameters:

dim - dimension

constructorCalled

public void constructorCalled(int offset)

toString

public String toString()

Overrides:

toString in class Object

commonSuperClassEx

public static CtClass commonSuperClassEx(CtClass one,
                                         CtClass two)
                                  throws NotFoundException

Finds the most specific common super class of the given classes by considering array types.

Throws:

NotFoundException

commonSuperClass

public static CtClass commonSuperClass(CtClass one,
                                       CtClass two)
                                throws NotFoundException

Finds the most specific common super class of the given classes. This method is a copy from javassist.bytecode.analysis.Type.

Throws:

NotFoundException

aastore
