Method Detail

extendsBound

public Type extendsBound()

Returns the extends (upper) bound of this wildcard. If this wildcard declares a super (lower) bound, this method will return null

Returns:

the extends bound, or null if this wildcard has a super bound

superBound

public Type superBound()

Returns the super (lower) bound of this wildcard. If this wildcard declares an extends (upper) bound, this method will return nnull

Returns:

the super bound, or null if this wildcard has a extends bound

bound

Type bound()

isExtends

boolean isExtends()

kind

public Type.Kind kind()

Description copied from class: Type

Returns the kind of Type this is.

Specified by:

kind in class Type

Returns:

the kind

asWildcardType

public WildcardType asWildcardType()

Description copied from class: Type

Casts this type to a WildcardType and returns it if the kind is Type.Kind.WILDCARD_TYPE Throws an exception otherwise.

Overrides:

asWildcardType in class Type

Returns:

a ClassType

toString

public java.lang.String toString()

Description copied from class: Type

Returns a string representation for this type. It is similar, yet not equivalent to a Java source code representation.

Overrides:

toString in class Type

Returns:

the string representation.

copyType

Type copyType(AnnotationInstance[] newAnnotations)

Specified by:

copyType in class Type

copyType

Type copyType(Type bound)

equals

public boolean equals(java.lang.Object o)

Description copied from class: Type

Compares this Type with another type, and returns true if they are equivalent. A type is equivalent to another type if it is the same kind, and all of its fields are equal. This includes annotations, which must be equal as well.

Overrides:

equals in class Type

Parameters:

o - the type to compare to

Returns:

true if equal

hashCode

public int hashCode()

Description copied from class: Type

Computes a hash code representing this type.

Overrides:

hashCode in class Type

Returns:

the hash code
