TypeVariable

public TypeVariable(TypeParameterDeclaration typeParameter)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

qualifiedName

public String qualifiedName()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

isArray

public boolean isArray()

Description copied from interface: Type

Does this type represent an array?

Specified by:

isArray in interface Type

isPrimitive

public boolean isPrimitive()

Description copied from interface: Type

Is this a primitive type?

Specified by:

isPrimitive in interface Type

replaceTypeVariables

public Type replaceTypeVariables(TypeParameterDeclaration tpToBeReplaced,
                                 Type replaced,
                                 Map<TypeParameterDeclaration,Type> inferredTypes)

Description copied from interface: Type

Replace all variables referring to the given TypeParameter with the given value. By replacing these values I could also infer some type equivalence. Those would be collected in the given map.

Specified by:

replaceTypeVariables in interface Type

isReferenceType

Specified by:

isReferenceType in interface Type

describe

Specified by:

describe in interface Type

asTypeParameter

Specified by:

asTypeParameter in interface Type

isTypeVariable

public boolean isTypeVariable()

Specified by:

isTypeVariable in interface Type

isAssignableBy

public boolean isAssignableBy(Type other)

Description copied from interface: Type

This method checks if ThisType t = new OtherType() would compile.

Specified by:

isAssignableBy in interface Type
