equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getS

public com.github.javaparser.resolution.types.ResolvedType getS()

usedInferenceVariables

public java.util.Set<InferenceVariable> usedInferenceVariables()

Specified by:

usedInferenceVariables in class Bound

getT

public com.github.javaparser.resolution.types.ResolvedType getT()

isProperUpperBound

public java.util.Optional<ProperUpperBound> isProperUpperBound()

Description copied from class: Bound

Given a bound of the form α <: T, we say T is a proper upper bound of α. Return empty if it is not a proper upper bound. Otherwise it returns the variable of which this is an proper upper bound.

Overrides:

isProperUpperBound in class Bound

isProperLowerBound

public java.util.Optional<ProperLowerBound> isProperLowerBound()

Description copied from class: Bound

Given a bound of the form T <: α, we say T is a proper lower bound of α. Return empty if it is not a proper lower bound. Otherwise it returns the variable of which this is an proper lower bound.

Overrides:

isProperLowerBound in class Bound

isADependency

public boolean isADependency()

Description copied from class: Bound

Other bounds relate two inference variables, or an inference variable to a type that contains inference variables. Such bounds, of the form S = T or S <: T, are called dependencies.

Overrides:

isADependency in class Bound

isSatisfied

public boolean isSatisfied(InferenceVariableSubstitution inferenceVariableSubstitution)

Description copied from class: Bound

A bound is satisfied by an inference variable substitution if, after applying the substitution, the assertion is true.

Specified by:
