DefaultTypeLoader

public DefaultTypeLoader(IModule module)

Method Details

instance

public static DefaultTypeLoader instance(IModule module)

instance

public static DefaultTypeLoader instance()

getType

public IType getType(String fullyQualifiedName)

Description copied from interface: ITypeLoader

Gets a type based on a fully-qualified name. This could either be the name of an entity, like "entity.User", the name of a typekey, like "typekey.SystemPermission", or a class name, like "java.lang.String". Names can have [] appended to them to create arrays, and multi-dimensional arrays are supported.

If the type can be successfully resolved by the typeloader, it will be returned, otherwise it will return null. The sole exception to this rule is the top-level TypeLoaderAccess, which will throw a ClassNotFoundException if none of its composite typeloaders can load the type.

There is a global lock in TypeLoaderAccess that is acquired when this method is called. Basically one type at a time can be loaded from the system. This method is free to release that lock during this call. This is needed to deal with reentrant type loaders. It is the responsibility of this method to make sure the lock is reacquired before this method returns.

Type loader access will guarentee that no duplicate types are put into the type loader.

Specified by:

getType in interface ITypeLoader

Parameters:

fullyQualifiedName - the fully qualified name of the type

Returns:

the corresponding IType or null

getInnerType

public IJavaType getInnerType(String fqn)

getJavaClassInfo

public IJavaClassInfo getJavaClassInfo(String fullyQualifiedName)

Specified by:

getJavaClassInfo in interface IDefaultTypeLoader

getJavaClassInfoForClassDirectly

public IJavaClassInfo getJavaClassInfoForClassDirectly(Class clazz,
 IModule module)

Specified by:

getJavaClassInfoForClassDirectly in interface IDefaultTypeLoader

getJavaClassInfo

public IJavaClassInfo getJavaClassInfo(Class aClass,
 IModule gosuModule)

getJavaClassInfo

public IJavaClassInfo getJavaClassInfo(AsmClass aClass,
 IModule gosuModule)

resolveJavaClassInfo

public IJavaClassInfo resolveJavaClassInfo(String fqn)

getSourceFileHandle

public ISourceFileHandle getSourceFileHandle(String qualifiedName)

Specified by:

getSourceFileHandle in interface IDefaultTypeLoader

getIntrinsicTypeFromObject

public IType getIntrinsicTypeFromObject(Object object)

Description copied from interface: IExtendedTypeLoader

Returns the intrinsic type for the given Object.

Specified by:

getIntrinsicTypeFromObject in interface IExtendedTypeLoader

Parameters:

object - the object to get an IType for

Returns:

the IType for the object

computeTypeNames

public Set<String> computeTypeNames()

Specified by:

computeTypeNames in interface ITypeLoader

getResource

public URL getResource(String name)

Description copied from interface: ITypeLoader

Finds the resource with the given name. A resource is some data that can be accessed by class code in a way that may be independent of the location of the code. The exact location of the resource is dependent upon the loader implementation

The name of a resource is a '/'-separated path name that identifies the resource.

Specified by:

getResource in interface ITypeLoader

Overrides:

getResource in class TypeLoaderBase

Parameters:

name - The resource name

Returns:

A URL object for reading the resource, or null if the resource could not be found or the invoker doesn't have adequate privileges to get the resource.

refreshedTypesImpl

Overrides:

refreshedTypesImpl in class TypeLoaderBase

isCaseSensitive

public boolean isCaseSensitive()

Specified by:

isCaseSensitive in interface ITypeLoader

Overrides:

isCaseSensitive in class TypeLoaderBase

Specified by:

handlesNonPrefixLoads in interface ITypeLoader

refreshedImpl

public void refreshedImpl()

Overrides:

refreshedImpl in class TypeLoaderBase

clearMisses

public void clearMisses()

loadClass

public Class loadClass(String className)

Specified by:

Specified by:

getAllNamespaces in interface ITypeLoader

Returns:

the set of package (aka namespace) names in which this loader's types reside.

refreshedNamespace

public void refreshedNamespace(String namespace,
 IDirectory dir,
 RefreshKind kind)

Specified by:

refreshedNamespace in interface ITypeLoader

getTypeNames

public Set<TypeName> getTypeNames(String namespace)

Specified by:

getInterface

public <T> T getInterface(Class<T> apiInterface)

Description copied from interface: IPluginHost

Provides an implementation of a specified interface.

Specified by:

getInterface in interface IPluginHost

Type Parameters:

T -

Parameters:

apiInterface -

Returns:

The implementation of the interface or null if unsupported.
