                            throws NotFoundException

Throws:

getEnclosingType

public JClassType getEnclosingType()

getField

public JField getField(java.lang.String name)

getFields

public JField[] getFields()

getJNISignature

public java.lang.String getJNISignature()

Specified by:

getJNISignature in class JType

getMetaData

public java.lang.String[][] getMetaData(java.lang.String tagName)

Description copied from interface: HasMetaData

Gets each list of metadata for the specified tag name.

Specified by:

getMetaData in interface HasMetaData

getMetaDataTags

public java.lang.String[] getMetaDataTags()

Description copied from interface: HasMetaData

Specified by:

getMetaDataTags in interface HasMetaData

getMethod

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

Throws:

getOracle

getOverloads

public JMethod[] getOverloads(java.lang.String name)

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.

Returns:

an array of JMethod objects representing overridable methods

getPackage

public JPackage getPackage()

getQualifiedSourceName

public java.lang.String getQualifiedSourceName()

Specified by:

getQualifiedSourceName in class JType

Throws:

isArray

public JArrayType isArray()

Specified by:

isArray in class JType

isAssignableFrom

isClass

public JClassType isClass()

Specified by:

isClass in class JType

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.

Returns:

true if the type is default instantiable, or false otherwise

isInterface

public JClassType isInterface()

Specified by:

isInterface in class JType

isLocalType

public boolean isLocalType()

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

Returns:

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.

Returns:

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