Constructor Detail

GcdLong_zxy

public GcdLong_zxy()

Method Detail

get_proto

public static FunctionBinary.GcdLong_zxy get_proto()

Returns the prototype invariant for GcdLong_zxy

instantiate_dyn

protected FunctionBinary.GcdLong_zxy instantiate_dyn( FunctionBinary.GcdLong_zxy this,
                                                     PptSlice slice)

instantiate an invariant on the specified slice

Specified by:

instantiate_dyn in class Invariant

Returns:

the new invariant

get_method_name

public String[] get_method_name(@GuardSatisfied FunctionBinary.GcdLong_zxy this)

get_function_id

public int get_function_id()

set_function_id

public void set_function_id(int function_id)

get_var_order

public int get_var_order(@GuardSatisfied FunctionBinary.GcdLong_zxy this)

is_symmetric

@Pure
public boolean is_symmetric()

func

public long func(long x,
                 long y)

check_modified

public InvariantStatus check_modified(long x,
                                      long y,
                                      long z,
                                      int count)

Description copied from class: ThreeScalar

Presents a sample to the invariant. Returns whether the sample is consistent with the invariant. Does not change the state of the invariant.

Specified by:

check_modified in class ThreeScalar

count - how many identical samples were observed in a row. For example, three calls to check_modified with a count parameter of 1 is equivalent to one call to check_modified with a count parameter of 3.

Returns:

whether or not the sample is consistent with the invariant

add_modified

public InvariantStatus add_modified(long x,
                                    long y,
                                    long z,
                                    int count)

Description copied from class: ThreeScalar

Similar to ThreeScalar.check_modified(long, long, long, int) except that it can change the state of the invariant if necessary. If the invariant doesn't have any state, then the implementation should simply call ThreeScalar.check_modified(long, long, long, int). This method need not check for falsification; that is done by the caller.

Specified by:

add_modified in class ThreeScalar

isGcd

@Pure
public boolean isGcd()

Overrides:

isGcd in class FunctionBinary

get_ni_suppressions

@Pure
public @Nullable NISuppressionSet get_ni_suppressions()

Returns a list of non-instantiating suppressions for this invariant.

Overrides:

get_ni_suppressions in class Invariant

Returns:

the set of non-instantiating suppressions for this invariant
