Constructor Summary public   ParameterNullnessProperty()      Constructor. Method Summary public  void copyFrom(ParameterNullnessProperty other)      Make this object the same as the given one. public  BitSet getAsBitSet()       int getNonNullParamSet()      Get the non-null param bitset. public  BitSet getViolatedParamSet(BitSet nullArgSet)      Given a bitset of null arguments passed to the method represented by this property, return a bitset indicating which null arguments correspond to an non-null param. public  void intersectWith(ParameterNullnessProperty targetDerefParamSet)      Intersect this set with the given set. public  boolean isEmpty()      Return whether or not the set of non-null parameters is empty. public  boolean isNonNull(int param)      Return whether or not a parameter might be non-null. public  void setNonNull(int param, boolean nonNull)      Set whether or not a parameter might be non-null.  void setNonNullParamSet(int nonNullParamSet)      Set the non-null param bitset. public  void setNonNullParamSet(BitSet nonNullSet)      Set the non-null param set from given BitSet. public  String toString()      Field Detail MAX_PARAMS final public static int MAX_PARAMS(Code) Maximum number of parameters that can be represented by a ParameterNullnessProperty. Constructor Detail ParameterNullnessProperty public ParameterNullnessProperty()(Code) Constructor. Parameters are all assumed not to be non-null. Method Detail copyFrom public void copyFrom(ParameterNullnessProperty other)(Code) Make this object the same as the given one. Parameters:   other - another ParameterNullnessProperty getAsBitSet public BitSet getAsBitSet()(Code) getNonNullParamSet int getNonNullParamSet()(Code) Get the non-null param bitset. the non-null param bitset getViolatedParamSet public BitSet getViolatedParamSet(BitSet nullArgSet)(Code) Given a bitset of null arguments passed to the method represented by this property, return a bitset indicating which null arguments correspond to an non-null param. Parameters:   nullArgSet - bitset of null arguments bitset intersecting null arguments and non-null params intersectWith public void intersectWith(ParameterNullnessProperty targetDerefParamSet)(Code) Intersect this set with the given set. Useful for summarizing the properties of multiple methods. Parameters:   targetDerefParamSet - another set isEmpty public boolean isEmpty()(Code) Return whether or not the set of non-null parameters is empty. true if the set is empty, false if it contains at least one parameter isNonNull public boolean isNonNull(int param)(Code) Return whether or not a parameter might be non-null. Parameters:   param - the parameter index true if the parameter might be non-null, false otherwise setNonNull public void setNonNull(int param, boolean nonNull)(Code) Set whether or not a parameter might be non-null. Parameters:   param - the parameter index Parameters:   nonNull - true if the parameter might be non-null, false otherwise setNonNullParamSet void setNonNullParamSet(int nonNullParamSet)(Code) Set the non-null param bitset. Parameters:   nonNullParamSet - the non-null param bitset setNonNullParamSet public void setNonNullParamSet(BitSet nonNullSet)(Code) Set the non-null param set from given BitSet. Parameters:   nonNullSet - BitSet indicating which parameters arenon-null toString public String toString()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
