Eclipse JDT
Release 3.5

org.eclipse.jdt.core.dom
Class Type

java.lang.Object
  extended by 

org.eclipse.jdt.core.dom.ASTNode
      extended by 
org.eclipse.jdt.core.dom.Type
Direct Known Subclasses:
ArrayType, ParameterizedType, PrimitiveType, QualifiedType, SimpleType, WildcardType

public abstract class Type
extends 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.

 Type:
    PrimitiveType
    ArrayType
    SimpleType
    QualifiedType
    ParameterizedType
    WildcardType
 PrimitiveType:
    byte
    short
    char
    int
    long
    float
    double
    boolean
    void
 ArrayType:
    Type [ ]
 SimpleType:
    TypeName
 ParameterizedType:
    Type < Type { , Type } >
 QualifiedType:
    Type . SimpleName
 WildcardType:
    ? [ ( extends | super) Type ]
 

Since:
2.0

Method Detail

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:

  1. QualifiedType(SimpleType(SimpleName("A")),SimpleName("B"))
  2. 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
