Method Detail

lookupPrimitive

public static PrimitiveType lookupPrimitive(java.lang.String name)

applyUnboxingConversion

public static PrimitiveType applyUnboxingConversion(JavaType input)

isNumeric

public static boolean isNumeric(PrimitiveType subject)

applyWideningConversion

public static boolean applyWideningConversion(PrimitiveType subject,
                                              PrimitiveType target)

JLS 5.1.2.

Returns:

True if subject may be widened to or is equal to the target.

applyNarrowingConversion

public static boolean applyNarrowingConversion(PrimitiveType subject,
                                               PrimitiveType target)

JLS 5.1.3.

Returns:

True if subject may be narrowed to or is equal to the target.

isNumeric

public boolean isNumeric()

isIntegral

public boolean isIntegral()

isFloatingPoint

public boolean isFloatingPoint()

getFile

public JavaFile getFile()

Specified by:

getFile in interface JavaElement

Returns:

Returns the JavaFile that this element is contained in.

If a SourceFile is returned, then this element is declared in or otherwise comes in a SourceFile.

A non-null JavaFile may be returned that is not a SourceFile. For example, a JavaClass that came from a .class file definition will return such a JavaFile instance.

If null, then this element was created on-the-fly.

getQualifiedName

public java.lang.String getQualifiedName()

Description copied from interface: JavaType

Gets the fully qualified name of this type in source format. Here, "source format" means the format of a type reference in a source compilation unit. A type's source name uniquely identifies a type in a specific scope but not in the global scope.

The source name of a non-parametrized top-level type of the form "pkg.Cls" is "pkg.Cls".

The source name of a non-parametrized member type of the form T.InnerClass (that is, a member type InnerClass that is a member of type T) is the source name of T suffixed with by ".InnerClass", e.g. "java.util.Map.Entry", "pkg.Cls<?>.InnerClass".

The source name of a parametrized type starts with the source name of the raw type and lists the source name of all of its actual type argumenths, e.g. "java.util.List<java.lang.String>". The source name of an array type T[] is the source name of T suffixed by the appropriate number of "[]"s.

The source name of a wildcard type is the string with which it would appear in a source file. The three possible forms this can take are: "?", "? extends T", "? super T".

The source name of a type parameter is just its name.

The source name of a primitive type should be pretty obvious.

The source name of a local inner class is just its name because a local inner class is referenced, in a source file, by its name.

An anonymous inner classes does not have a source name. It will return the empty string for its source name.

Open for discussion: What should be returned by an anonymous class? Technically, the concept of a source name is irrelevant because anonymous classes may not be referred to in a source compilation unit.

Specified by:

getQualifiedName in interface JavaType

Specified by:

getQualifiedName in class AbstractType

Returns:

The fully qualified source name for this type, empty for anonymous classes. Example values: java.lang.Object java.util.Map<String,String> java.lang.String[][]

getVMName

public java.lang.String getVMName()

Description copied from interface: JavaType

Gets the VM name for this type. The JVMS3 defines an internal name format for raw classes. We call this the VM name of a type. It's useful for loading known types such as "java/lang/Object" and "java/lang/Throwable". Here is how we define the "VM name" for all types:

The VM name of a non-parametrized top-level type of the form "pkg.Cls" is "pkg/Cls".

The VM name of a non-parametrized member-level type of the form "pkg.Cls.InnerClass" is "pkg/Cls$InnerClass".

The VM name of a parametrized type is the VM name of the raw type. Because parametrization is stripped at run-time, we will omit it from the VM name.

The VM name of an array type T[] is the VM name of T suffixed by the appropriate number of "[]"s.

The VM name of a local inner class or anonymous inner class is a string that uniquely identifies it from all other types and is usually prefixed with the VM name of its directly enclosing class. For example, an anonymous inner class belonging to the type "pkg.Cls" may return "pkg/Cls$1".

The VM name of any other type is the same as its source name.

Specified by:

getVMName in interface JavaType

Specified by:

getVMName in class AbstractType

Returns:

The raw name, also known as the VM name, of this type. e.g. "java/lang/Object", "java/util/Map$Entry"

getName

public java.lang.String getName()

Description copied from interface: JavaType

Gets the simplest name of this type with "[]"s if present.

The name of a non-parametrized top-level type of the form "pkg.Cls" is "Cls".

The name of a non-parametrized member type of the form "pkg.Cls.InnerClass" is "InnerClass".

The name of an array type T[] is the name of T suffixed by the appropriate number of "[]"s.

The name of a parametrized type is the same as the name of its raw type. That is, the name of "pkg.Cls<String>" is simply "Cls".

The name of a wildcard type is always "?".

The name of a type parameter should be pretty obvious.

The name of a primitive type should be pretty obvious.

The name of a local inner class is just its name.

An anonymous inner classes does not have a name and will return the empty string.

Specified by:

getName in interface JavaHasName

Specified by:

getName in interface JavaType

Specified by:

getName in class AbstractType

Returns:

The simple name of this type with "[]"s if present.

getDescriptor

public java.lang.String getDescriptor()

Description copied from interface: JavaType

Gets the descriptor for this type, as defined by the JVMS2. Note: The descriptor is equivalent to the type signature of this type's erasure.

For jdk < 1.5, the "FieldDescriptor" is returned (JVMS2). For jdk < 1.5, descriptors and signatures are the same thing.

For jdk >= 1.5, a type signature of the type erasure is returned.

Note: Do not confuse a type's descriptor with a method's descriptor. The descriptor of the type of a method is the field descriptor describing its return type. The descriptor of a method describes parameter types.

Specified by:

getDescriptor in interface JavaType

Overrides:

getDescriptor in class AbstractClass

Returns:

The descriptor as defined in the JVMS2. Always non-null. Example values: "I", "Ljava/lang/Object;"

getTypeSignature

public java.lang.String getTypeSignature()

Description copied from interface: JavaType

Gets the type signature for this type, as defined by the JVMS3.

A JavaClass returns its "ClassTypeSignature" (JVMS3). A JavaClass is uniquely identified by its type signature. Example value: Ljava/util/List<Ljava/lang/Object;>;

A JavaTypeVariable returns its "TypeVariableSignature" (JVMS3). A type variable is uniquely identified by the combination of its owning declaration AND its type signature. Example value: TE;

A WildcardType returns its "TypeArgument" value (JVMS3). A wildcard type is uniquely identified by its type signature. Example values: * +Ljava/lang/Object;.

Specified by:

getTypeSignature in interface JavaType

Overrides:

getTypeSignature in class AbstractClass

Returns:

The type signature as defined in the JVMS3. Always non-null.

getSignature

public java.lang.String getSignature()

Description copied from interface: JavaType

Gets the "Signature" attribute of this type, as defined by the JVMS3.

The "Signature" attribute for a field is the "ClassTypeSignature" for its type.

The "Signature" attribute for a method involves the "ClassSignature"s for its type parameters and the "ClassTypeSignature"s of its remaining constituent types.

A JavaClass returns its "ClassSignature" (JVMS3).

A JavaTypeVariable does not have a class signature, but will return a string for use in a class signature or a method signature.

A WildcardType does not have a class signature and may not part of a class signature. Its return value is undefined.

Specified by:

getSignature in interface JavaType

Overrides:

getSignature in class AbstractClass

Returns:

The class signature as defined in the JVMS3. "A signature is a string representing the generic type of a field or method, or generic type information for a class declaration." Always non-null.

getModifiers

public int getModifiers()

Specified by:

getModifiers in interface JavaElement

Overrides:

getModifiers in class AbstractType

Returns:

The access modifiers on this element.

isPrimitive

public boolean isPrimitive()

Specified by:

isPrimitive in interface JavaType

Overrides:

isPrimitive in class AbstractType

Returns:

True if this type is a primitive type.
