Method Detail

valid_types

public final boolean valid_types(VarInfo[] vis)

Returns whether or not the specified types are valid.

Specified by:

valid_types in class Invariant

See Also:

Invariant.instantiate_ok(VarInfo[])

add

public InvariantStatus add(@Interned Object val,
                           int mod_index,
                           int count)

Specified by:

add in class UnaryInvariant

check

public InvariantStatus check(@Interned Object val,
                             int mod_index,
                             int count)

Specified by:

check in class UnaryInvariant

add_modified

public abstract InvariantStatus add_modified(double @Interned [] value,
                                             int count)

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

add_unmodified

public InvariantStatus add_unmodified(double @Interned [] value,
                                      int count)

By default, do nothing if the value hasn't been seen yet. Subclasses can override this.

check_modified

public abstract InvariantStatus check_modified(double @Interned [] value,
                                               int count)

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

Parameters:

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

check_unmodified

public InvariantStatus check_unmodified(double @Interned [] value,
                                        int count)
