Method Detail

getErasedType

JType getErasedType()
Returns this type with no type parameters or type variables. See the JLS Third Edition section on Type Erasure.

getJNISignature

java.lang.String getJNISignature()
Returns the "field descriptor" for a type as specified by the Java Virtual Machine Specification. Examples:

getLeafType

JType getLeafType()
For array types, recursively looks for the element type that is not an array. Otherwise, returns this type.

getParameterizedQualifiedSourceName

java.lang.String getParameterizedQualifiedSourceName()
Returns a type name as it would be specified in Java source, with the package name included. Includes the type parameters. If called on a type parameter, does not include any bounds. For example, a type Foo declared in com.example would be given as "com.example.Foo", while the same type instantiated with Baz would be "com.example.Foo".

getQualifiedBinaryName

java.lang.String getQualifiedBinaryName()
A binary type name as specified by the Java Language Spec, ThirdEdition.

getQualifiedSourceName

java.lang.String getQualifiedSourceName()
Returns a type name as it would be specified in Java source, with the package name included. Does not include the type parameters. If called on a type parameter, includes any bounds.

getSimpleSourceName

java.lang.String getSimpleSourceName()
Returns the name of this class without the package name or enclosing class name.

isAnnotation

JAnnotationType isAnnotation()
Returns this instance as a JAnnotationType if it is an annotation or null if it is not.

isArray

JArrayType isArray()

isClass

JClassType isClass()
Returns this instance if the erased version of this type is a class (as opposed to a primitive, array, or interface) or null if it is not.

isClassOrInterface

JClassType isClassOrInterface()
Returns this instance if the erased version of this type is a class or interface (as opposed to a primitive or array array) or null if it is not.

isEnum

JEnumType isEnum()
Returns this instance if it is an enumeration or null if it is not.

isGenericType

JGenericType isGenericType()
Returns this instance if it is a real class that has type parameters or null if it is not.

isInterface

JClassType isInterface()
Returns this instance if it is an interface or null if it is not.

isParameterized

JParameterizedType isParameterized()
Returns this instance as a JParameterizedType if it is a parameterized type or null if it is not.

isPrimitive

JPrimitiveType isPrimitive()

isRawType

JRawType isRawType()
Returns the raw type if this is a JRawType, otherwise returns null.

isTypeParameter

JTypeParameter isTypeParameter()

isWildcard

JWildcardType isWildcard()
