randoop.types.EagerReferenceBound

class EagerReferenceBound
extends ReferenceBound

Represents a bound on a type variable where the bound is a ReferenceType that can be used directly. Contrast with LazyReferenceBound.

Constructor Detail

EagerReferenceBound

EagerReferenceBound(ReferenceType boundType)

Creates a bound for the given reference type.

Parameters:

boundType - the reference boundType

Method Detail

substitute

public EagerReferenceBound substitute(Substitution substitution)

Description copied from class: ParameterBound

Applies the given substitution to this type bound by replacing type variables.

Specified by:

substitute in class ReferenceBound

Parameters:

substitution - the type substitution

Returns:

this bound with the type after the substitution has been applied

applyCaptureConversion

public EagerReferenceBound applyCaptureConversion()

Description copied from class: ParameterBound

Applies a capture conversion to any wildcard arguments in the type of this bound.

Specified by:

applyCaptureConversion in class ReferenceBound

Returns:

this type with any wildcards replaced by capture conversion

See Also:

ReferenceType.applyCaptureConversion()

getTypeParameters

public java.util.List<TypeVariable> getTypeParameters()

Description copied from class: ParameterBound

Returns any type parameters in the type of this bound.

Specified by:

getTypeParameters in class ParameterBound

Returns:

the list of TypeVariable objects in this bound

isLowerBound

public boolean isLowerBound(Type argType,
                            Substitution subst)

Description copied from class: ParameterBound

Indicates whether this bound is a lower bound of the given argument type.

Specified by:

isLowerBound in class ParameterBound

Parameters:

argType - the concrete argument type

subst - the substitution

Returns:

true if this bound is a subtype of the given type

isLowerBound

boolean isLowerBound(ParameterBound bound,
                     Substitution substitution)

Description copied from class: ParameterBound

Tests whether this is a lower bound on the type of a given bound with respect to a type substitution. The body is approximately:

 return this.substitute(substitution).isLowerBound(bound.substitute(substitution);
 

Overrides:

isLowerBound in class ParameterBound

Parameters:

bound - the other bound

substitution - the type substitution

Returns:

true iff this bound is a lower bound on the type of the given bound

isSubtypeOf

public boolean isSubtypeOf(ParameterBound bound)

Description copied from class: ParameterBound

Indicates whether the type of this bound is a subtype of the type of the given bound.

Specified by:

isSubtypeOf in class ParameterBound

Parameters:

bound - the other bound

Returns:

true if this type is a subtype of the other bound, false otherwise

isUpperBound

public boolean isUpperBound(Type argType,
                            Substitution subst)

Description copied from class: ParameterBound

Determines if this bound is an upper bound for the argument type.

Specified by:

isUpperBound in class ParameterBound

Parameters:

argType - the concrete argument type

subst - the substitution

Returns:

true if this bound is satisfied by the concrete type when the substitution is used on the bound, false otherwise

isUpperBound

boolean isUpperBound(ParameterBound bound,
                     Substitution substitution)

Description copied from class: ParameterBound

Indicates whether this bound is an upper bound on the type of the given bound with respect to the type substitution.

Specified by:

isUpperBound in class ParameterBound

Parameters:

bound - the other bound

substitution - the type substitution

Returns:

true if this bound is an upper bound on the type of the given bound, false otherwise
