Interface NodeWithTypeArguments<N extends Node>

All Known Implementing Classes:

ClassOrInterfaceType, ExplicitConstructorInvocationStmt, FieldAccessExpr, MethodCallExpr, MethodReferenceExpr, ObjectCreationExpr

public interface NodeWithTypeArguments<N extends Node>

A node that can have type arguments.

     new X();        --> typeArguments == Optional is empty
     new X<>();      --> typeArguments = [], diamondOperator = true
     new X<C,D>();   --> typeArguments = [C,D], diamondOperator = false
 

Only ObjectCreationExpr uses the diamond operator. On other nodes it is treated the same as the first case.

Method Summary

Modifier and Type	Method and Description
Optional<NodeList<Type>>	getTypeArguments()
default boolean	isUsingDiamondOperator()
default N	removeTypeArguments() Removes all type arguments, including the surrounding <>.
default N	setDiamondOperator() Sets the type arguments to <>.
N	setTypeArguments(NodeList<Type> typeArguments) Allows you to set the generic arguments
default N	setTypeArguments(Type... typeArguments)

Method Detail

getTypeArguments

Optional<NodeList<Type>> getTypeArguments()

Returns:

the types that can be found in the type arguments: <String, Integer>.

setTypeArguments

N setTypeArguments(NodeList<Type> typeArguments)

Allows you to set the generic arguments

Parameters:

typeArguments - The list of types of the generics, can be null

isUsingDiamondOperator

default boolean isUsingDiamondOperator()

Returns:

whether the type arguments look like <>.

setDiamondOperator

default N setDiamondOperator()

Sets the type arguments to <>.

removeTypeArguments

default N removeTypeArguments()

Removes all type arguments, including the surrounding <>.

setTypeArguments

default N setTypeArguments(Type... typeArguments)
