SymTypeInferenceVariable	asInferenceVariable()
SymTypeInferenceVariable	deepClone()
boolean	deepEquals(SymTypeExpression sym)
boolean	denotesSameVar(SymTypeExpression other)	Similar to deepEquals, but only checks whether the variables are supposed to be the same variable.
SymTypeExpression	getLowerBound()
protected static int	getUniqueID()
SymTypeExpression	getUpperBound()
boolean	isInferenceVariable()	Am I a free type variable?
boolean	isPrimitive()	Am I primitive? (such as "int") (default: no)

Field Details

id

protected int id

This holds a number of the free type variable, which acts as an identifier. The Only guarantee is that the ids are unique. Never test against them.

idStr

protected String idStr

a short string, e.g., "FV", that is output with the id while printing

lowerBound

protected SymTypeExpression lowerBound

upperBound

protected SymTypeExpression upperBound

typeInfIDCounter

protected static AtomicInteger typeInfIDCounter

Constructor Details

SymTypeInferenceVariable

public SymTypeInferenceVariable(String idStr,
 SymTypeExpression lowerBound,
 SymTypeExpression upperBound)

SymTypeInferenceVariable

public SymTypeInferenceVariable(int id,
 String idStr,
 SymTypeExpression lowerBound,
 SymTypeExpression upperBound)

INTERNAL, DO NOT USE: used for deepcloning

Method Details

getLowerBound

public SymTypeExpression getLowerBound()

getUpperBound

public SymTypeExpression getUpperBound()

_internal_getID

public int _internal_getID()

accessible for printing, sorting, etc. usually, you do not need/want this.

_internal_getIDStr

public String _internal_getIDStr()

accessible for printing usually, you do not need/want this.

isPrimitive

public boolean isPrimitive()

Description copied from class: SymTypeExpression

Am I primitive? (such as "int") (default: no)

Overrides:

isPrimitive in class SymTypeExpression

isInferenceVariable

public boolean isInferenceVariable()

Description copied from class: SymTypeExpression

Am I a free type variable?

Overrides:

isInferenceVariable in class SymTypeExpression

asInferenceVariable

public SymTypeInferenceVariable asInferenceVariable()

Overrides:

asInferenceVariable in class SymTypeExpression

deepClone

public SymTypeInferenceVariable deepClone()

Overrides:

deepClone in class SymTypeExpression

denotesSameVar

public boolean denotesSameVar(SymTypeExpression other)

Similar to deepEquals, but only checks whether the variables are supposed to be the same variable. E.g., bounds are ignored

deepEquals

public boolean deepEquals(SymTypeExpression sym)

Specified by:

deepEquals in class SymTypeExpression

accept

public void accept(ISymTypeVisitor visitor)

Overrides:

accept in class SymTypeExpression

getUniqueID

protected static int getUniqueID()
