Method Details

accept

public <R,
A> R accept(GenericVisitor<R,A> v,
 A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

R - the type of the return value of the visitor

A - the type the user argument passed to the visitor

Parameters:

v - the visitor implementation

arg - the argument passed to the visitor (of type A)

Returns:

the result of the visit (of type R)

accept

public <A> void accept(VoidVisitor<A> v,
 A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

A - the type the argument passed for the visitor

Parameters:

v - the visitor implementation

arg - any value relevant for the visitor (of type A)

getName

public SimpleName getName()

Specified by:

getName in interface NodeWithSimpleName<FieldAccessExpr>

setName

public FieldAccessExpr setName(SimpleName name)

Specified by:

setName in interface NodeWithSimpleName<FieldAccessExpr>

getScope

public Expression getScope()

Specified by:

getScope in interface NodeWithScope<FieldAccessExpr>

setScope

public FieldAccessExpr setScope(Expression scope)

Sets the scope

Specified by:

setScope in interface NodeWithScope<FieldAccessExpr>

Parameters:

scope - the scope, can not be null

Returns:

this, the FieldAccessExpr

getTypeArguments

public Optional<NodeList<Type>> getTypeArguments()

Specified by:

getTypeArguments in interface NodeWithTypeArguments<FieldAccessExpr>

Returns:

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

setTypeArguments

public FieldAccessExpr setTypeArguments(NodeList<Type> typeArguments)

Sets the type arguments

Specified by:

setTypeArguments in interface NodeWithTypeArguments<FieldAccessExpr>

Parameters:

typeArguments - the type arguments, can be null

Returns:

this, the FieldAccessExpr

clone

public FieldAccessExpr clone()

Overrides:

clone in class Expression

getMetaModel

public FieldAccessExprMetaModel getMetaModel()

Overrides:

getMetaModel in class Expression

Returns:

get JavaParser specific node introspection information.

remove

public boolean remove(Node node)

Overrides:

remove in class Node

replace

public boolean replace(Node node,

resolve

public ResolvedValueDeclaration resolve()

Attempts to resolve the declaration corresponding to the accessed field. If successful, a ResolvedValueDeclaration representing the declaration of the value accessed by this FieldAccessExpr is returned. Otherwise, an UnsolvedSymbolException is thrown.

Specified by:

resolve in interface Resolvable<ResolvedValueDeclaration>

Returns:

a ResolvedValueDeclaration representing the declaration of the accessed value.

Throws:

UnsolvedSymbolException - if the declaration corresponding to the field access expression could not be resolved.
