public interface JavaIsGeneric
extends JavaMember

A generic declaration declares type parameters. Both types and methods (constructors too) may declare type parameters. A bound declaration may be created from a generic declaration.

Method Detail

hasTypeParameters

boolean hasTypeParameters()

Returns:

True if this member has type parameters.

getTypeParameters

java.util.Collection<JavaTypeVariable> getTypeParameters()

Returns:

The array of type parameters for this generic type. Zero-length if this type is not of generic type. Returns a Collection of JavaTypeVariable's.

getTypeParameter

JavaTypeVariable getTypeParameter(java.lang.String name)

Returns:

The matching type parameter. Null means no match.

hasActualTypeArguments

boolean hasActualTypeArguments()

Determine if this type or member has explicit or implicit (in the case of the diamond syntax) type arguments, e.g. will return true for 'Type' in 'new Type<Integer>()' and in 'new Type<>()' and false for 'Type' in 'new Type()'

Returns:

True if this member has explicit or implicit type arguments.

getActualTypeArguments

java.util.Collection<JavaType> getActualTypeArguments()

Get the type arguments, if any.

Returns:

The array of actual type arguments this type or member is bound to. Zero-length if this type is not generic or is not bound or is a type with implied type arguments, such as from the diamond syntax for new class expressions. Returns a Collection of JavaType's.
