Method Detail

getName

String getName()

Full name of the type represented by the node. In the case of representing a Generics type, like @code{}, it contains the name of the variable.

Returns:

Full name of the type

getClazz

Class<?> getClazz()

The class referenced by the node. In the case of simple type references, this is the class corresponding to an specific enumeration, annotation or type. In case of field references, method calls, field declaration or method declaration, represents the class of the field or the returning type of the method. In case of a Generics variable, it corresponds to the defined bounds or the

Returns:

the referenced class

getBoundClasses

List<Class<?>> getBoundClasses()

Java Generics allows expressions like . These boundary classes corresponds to A, B and C. When there are not multiple classes it returns the same than @link{#getClass() getClass}.

Returns:

the bound classes

getArrayCount

int getArrayCount()

Returns in case of arrays, it returns the dimensions.

Returns:

the dimensions of the array type.

isTemplateVariable

boolean isTemplateVariable()

Returns if it is a template variable used in a Java Generics expression.

Returns:

if it is a generics variable.

getParameterizedTypes

<T extends SymbolData> List<T> getParameterizedTypes()

Returns the parametrized types of a generics expression. For example: if the referenced type is List, it corresponds to String.

Returns:

merge

SymbolData merge(SymbolData other)

Merges to symbol data types calculating the common type hierarchy. This interface has been useful to calculate the result type of a lambda expression.

Parameters:

other - another symbol data.

Returns:

a symbol data resulting of merging two symbol datas.

getLowerBoundClasses

List<Class<?>> getLowerBoundClasses()

Java Generics allows expressions like . These lower boundary classes corresponds to A, B and C.

Returns:

the lower bound classes
