Constructor Detail

MultiplyDouble_zxy

public MultiplyDouble_zxy()

Method Detail

get_proto

public static FunctionBinaryFloat.MultiplyDouble_zxy get_proto()

Returns the prototype invariant for MultiplyDouble_zxy

instantiate_dyn

protected FunctionBinaryFloat.MultiplyDouble_zxy instantiate_dyn( FunctionBinaryFloat.MultiplyDouble_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 FunctionBinaryFloat.MultiplyDouble_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 FunctionBinaryFloat.MultiplyDouble_zxy this)

is_symmetric

@Pure
public boolean is_symmetric()

func

public double func(double x,
                   double y)

check_modified

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

Description copied from class: ThreeFloat

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 ThreeFloat

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(double x,
                                    double y,
                                    double z,
                                    int count)

Description copied from class: ThreeFloat

Similar to ThreeFloat.check_modified(double, double, double, 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 ThreeFloat.check_modified(double, double, double, int). This method need not check for falsification; that is done by the caller.

Specified by:

add_modified in class ThreeFloat

isMultiply

@Pure
public boolean isMultiply()

Overrides:

isMultiply in class FunctionBinaryFloat

isExact

@Pure
public boolean isExact()

Description copied from class: Invariant

Subclasses should override. An exact invariant indicates that given all but one variable value, the last one can be computed. (I think that's correct, anyway.) Examples are IntComparison (when only equality is possible), LinearBinary, FunctionUnary. OneOf is treated differently, as an interface. The result of this method does not depend on whether the invariant is justified, destroyed, etc.

Overrides:

isExact in class Invariant

Returns:

true if any variable value can be computed from all the others

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
