Field Detail

dkconfig_enabled

public static boolean dkconfig_enabled

Boolean. True iff SequenceStringArbitrarySubsequence derived variables should be generated.

left_closed

public final boolean left_closed

right_closed

public final boolean right_closed

Method Detail

seqvar

public VarInfo seqvar()

startvar

public VarInfo startvar()

endvar

public VarInfo endvar()

computeValueAndModified

public ValueAndModified computeValueAndModified(ValueTuple full_vt)

Description copied from class: Derivation

Returns a pair of: the derived value and whether the variable counts as modified.

Specified by:

computeValueAndModified in class TernaryDerivation

Parameters:

full_vt - the set of values in a program point that will be used to derive the value

Returns:

a pair of: the derived value and whether the variable counts as modified

makeVarInfo

protected VarInfo makeVarInfo()

Description copied from class: Derivation

Used by all child classes to actually create the VarInfo this represents, after which it is interned for getVarInfo().

Specified by:

makeVarInfo in class Derivation

get_lower_bound

public Quantify.Term get_lower_bound()

Returns the lower bound of the slice.

Overrides:

get_lower_bound in class Derivation

get_upper_bound

public Quantify.Term get_upper_bound()

Returns the upper bound of the slice.

Overrides:

get_upper_bound in class Derivation

get_array_var

public VarInfo get_array_var()

Returns the array variable for this slice.

Overrides:

get_array_var in class Derivation

isSameFormula

@Pure
public boolean isSameFormula(Derivation other)

Description copied from class: Derivation

Returns true iff other and this represent the same derivation (modulo the variable they are applied to). Default implentation will just checks run-time type, but subclasses with state (e.g. SequenceInitial index) should match that, too.

Specified by:

isSameFormula in class Derivation

Parameters:

other - the Derivation to compare to

Returns:

true iff other and this represent the same derivation

csharp_name

@SideEffectFree
public String csharp_name(String index)

Returns the csharp name.

Overrides:

csharp_name in class Derivation

esc_name

@SideEffectFree
public String esc_name(String index)

Returns the ESC name.

Overrides:

esc_name in class Derivation
