Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`JType`	`getErasedType()` Returns this type with no type parameters or type variables.
`java.lang.String`	`getJNISignature()` Returns the "field descriptor" for a type as specified by the Java Virtual Machine Specification.
`JType`	`getLeafType()` For array types, recursively looks for the element type that is not an array.
`java.lang.String`	`getParameterizedQualifiedSourceName()` Returns a type name as it would be specified in Java source, with the package name included.
`java.lang.String`	`getQualifiedBinaryName()` A binary type name as specified by the Java Language Spec, ThirdEdition.
`java.lang.String`	`getQualifiedSourceName()` Returns a type name as it would be specified in Java source, with the package name included.
`java.lang.String`	`getSimpleSourceName()` Returns the name of this class without the package name or enclosing class name.
`JAnnotationType`	`isAnnotation()` Returns this instance as a `JAnnotationType` if it is an annotation or `null` if it is not.
`JArrayType`	`isArray()`
`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.
`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.
`JEnumType`	`isEnum()` Returns this instance if it is an enumeration or `null` if it is not.
`JGenericType`	`isGenericType()` Returns this instance if it is a real class that has type parameters or `null` if it is not.
`JClassType`	`isInterface()` Returns this instance if it is an interface or `null` if it is not.
`JParameterizedType`	`isParameterized()` Returns this instance as a `JParameterizedType` if it is a parameterized type or `null` if it is not.
`JPrimitiveType`	`isPrimitive()`
`JRawType`	`isRawType()` Returns the raw type if this is a `JRawType`, otherwise returns `null`.
`JTypeParameter`	`isTypeParameter()`
`JWildcardType`	`isWildcard()`

- 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:
    - boolean = Z
    - byte[] = [B
    - java.lang.String = Ljava/lang/String;
  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()
