Constructor Detail

EnhancerJavaModel

public EnhancerJavaModel(java.lang.ClassLoader classLoader,
                 ResourceLocator locator)

Creates an instance.

Method Detail

getInputStreamForResource

public java.io.InputStream getInputStreamForResource(java.lang.String resourceName)

Finds a resource with a given name. This method returns null if no resource with this name is found. The name of a resource is a "/"-separated path name.

Specified by:

getInputStreamForResource in interface JavaModel

Overrides:

getInputStreamForResource in class ReflectionJavaModel

Parameters:

resourceName - the resource name

Returns:

an input stream for reading the resource, or null if the resource could not be found or if the caller doesn't have adequate privileges to get the resource.

createJavaType

protected JavaType createJavaType(java.lang.Class clazz)

Creates a new JavaType instance for the specified Class object.

This implementation returns a EnhancerJavaType instance.

Specified by:

createJavaType in class ReflectionJavaModel

Parameters:

clazz - the Class instance representing the type

Returns:

a new JavaType instance

getTypeName

public java.lang.String getTypeName(java.lang.String sig)

Returns the fully qualified name of the specified type representation.

affirm

protected static final void affirm(boolean condition,
          java.lang.String msg)
