ASTNode
Abstract base class of all type AST node types. A type node represents a
reference to a primitive type (including void), to an array type, or to a
simple named type (or type variable), to a qualified type, to a
parameterized type, or to a wildcard type. Note that not all of these
are meaningful in all contexts; for example, a wildcard type is only
meaningful in the type argument position of a parameterized type.

isPrimitiveType
public final boolean isPrimitiveType()
- Returns whether this type is a primitive type
(
PrimitiveType ).
-
-
Returns:
-
true if this is a primitive type, and
false otherwise
isSimpleType
public final boolean isSimpleType()
- Returns whether this type is a simple type
(
SimpleType ).
-
-
Returns:
-
true if this is a simple type, and
false otherwise
isArrayType
public final boolean isArrayType()
- Returns whether this type is an array type
(
ArrayType ).
-
-
Returns:
-
true if this is an array type, and
false otherwise
isParameterizedType
public final boolean isParameterizedType()
- Returns whether this type is a parameterized type
(
ParameterizedType ).
-
-
Returns:
-
true if this is a parameterized type, and
false otherwise -
Since:
- 3.1
isQualifiedType
public final boolean isQualifiedType()
- Returns whether this type is a qualified type
(
QualifiedType ).
Note that a type like "A.B" can be represented either of two ways:
-
QualifiedType(SimpleType(SimpleName("A")),SimpleName("B"))
-
SimpleType(QualifiedName(SimpleName("A"),SimpleName("B")))
The first form is preferred when "A" is known to be a type. However, a
parser cannot always determine this. Clients should be prepared to handle
either rather than make assumptions. (Note also that the first form
became possible as of JLS3; only the second form existed in the
JLS2 API.)
-
-
Returns:
-
true if this is a qualified type, and
false otherwise -
Since:
- 3.1
isWildcardType
public final boolean isWildcardType()
- Returns whether this type is a wildcard type
(
WildcardType ).
Note that a wildcard type is only meaningful as a
type argument of a ParameterizedType node.
-
-
Returns:
-
true if this is a wildcard type, and
false otherwise -
Since:
- 3.1
resolveBinding
public final
ITypeBinding resolveBinding()
- Resolves and returns the binding for this type.
Note that bindings are generally unavailable unless requested when the
AST is being built.
-
-
Returns:
- the type binding, or
null if the binding cannot be
resolved
