#### Parameters

name

### findMethod

public JMethod findMethod(String name, JType[] paramTypes)

#### Parameters

name
paramTypes

### findNestedType

public JClassType findNestedType(String typeName)

#### Parameters

typeName

### getBodyEnd

public int getBodyEnd()

### getBodyStart

public int getBodyStart()

### getCompilationUnit

public CompilationUnitProvider getCompilationUnit()

### getConstructor

public JConstructor getConstructor(JType[] paramTypes)
throws NotFoundException

#### Parameters

paramTypes

### getConstructors

public JConstructor[] getConstructors()

### getEnclosingType

public JClassType getEnclosingType()

### getField

public JField getField(String name)

#### Parameters

name

### getFields

public JField[] getFields()

### getImplementedInterfaces

public JClassType[] getImplementedInterfaces()

### getJNISignature

public abstract String getJNISignature()

### getMetaData

public String[][] getMetaData(String tagName)
Gets each list of metadata for the specified tag name.

#### Parameters

tagName

### getMetaDataTags

public String[] getMetaDataTags()
Gets the name of available metadata tags.

### getMethod

public JMethod getMethod(String name, JType[] paramTypes)
throws NotFoundException

#### Parameters

### getOverridableMethods

public JMethod[] getOverridableMethods()
Iterates over the most-derived declaration of each unique overridable method available in the type hierarchy of the specified type, including those found in superclasses and superinterfaces. A method is overridable if it is not `final` and its accessibility is `public`, `protected`, or package protected. Deferred binding generators often need to generate method implementations; this method offers a convenient way to find candidate methods to implement. Note that the behavior does not match Class.getMethod(String, Class[]), which does not return the most derived method in some cases.

#### Return Value

an array of JMethod objects representing overridable methods

### getPackage

public JPackage getPackage()

### getQualifiedSourceName

public abstract String getQualifiedSourceName()

### getSimpleSourceName

public abstract String getSimpleSourceName()

### getSubtypes

public JClassType[] getSubtypes()

### getSuperclass

public JClassType getSuperclass()

### getTypeHash

public String getTypeHash()
throws UnableToCompleteException

### isAbstract

public boolean isAbstract()

### isArray

public abstract JArrayType isArray()

### isAssignableFrom

public boolean isAssignableFrom(JClassType possibleSubtype)

#### Parameters

possibleSubtype

### isAssignableTo

public boolean isAssignableTo(JClassType possibleSupertype)

#### Parameters

possibleSupertype

### isClass

public abstract JClassType isClass()

### isDefaultInstantiable

public boolean isDefaultInstantiable()
Determines if the class can be constructed using a simple `new` operation. Specifically, the class must

- be a class rather than an interface,
- have either no constructors or a parameterless constructor, and
- be a top-level class or a static nested class.

#### Return Value

`true` if the type is default instantiable, or `false` otherwise

### isInterface

public abstract JClassType isInterface()

### isLocalType

public boolean isLocalType()
Tests if this type is a local type (within a method).

#### Return Value

true if this type is a local type, whether it is named or anonymous.

### isMemberType

public boolean isMemberType()
Tests if this type is contained within another type.

#### Return Value

true if this type has an enclosing type, false if this type is a top-level type

### isParameterized

public abstract JParameterizedType isParameterized()

### isPrimitive

public abstract JPrimitiveType isPrimitive()

### isPrivate

public boolean isPrivate()

### isProtected

public boolean isProtected()

### isPublic

public boolean isPublic()

### isStatic

public boolean isStatic()

### setSuperclass

public void setSuperclass(JClassType type)

#### Parameters

type

### toString
