Class
Description
AbstractChainableUberspector
Default implementation of a `chainable uberspector` that forwards all calls to the wrapped uberspector (when that is possible).
ChainableUberspector
Interface that marks uberspectors as chainable, meaning that multiple uberspectors can be combined in a chain (using the Decorator pattern).
ClassFieldMap
A cache of introspection information for a specific class instance.
ClassMap
A cache of introspection information for a specific class instance.
ConversionHandler
Deprecated.
use `TypeConversionHandler`
Converter<T>
Converts a value to type T
DeprecatedCheckUberspector
Chainable Uberspector that checks for deprecated method calls.
Info
Little class to carry in info such as template name, line and column for information error reporting from the uberspector implementations
IntrospectionCacheData
Holds information for node-local context data introspection information.
IntrospectionUtils
Introspector
This basic function of this class is to return a Method object for a particular class given the name of a method and the parameters to the method in the form of an Object[] The first time the Introspector sees a class it creates a class method map for the class in question.
IntrospectorBase
Lookup a a Method object for a particular class given the name of a method and its parameters.
IntrospectorCache
This is the internal introspector cache implementation.
LinkingUberspector
When the introspector.uberspect.class configuration property contains several uberspector class names, it means those uberspectors will be chained.
MethodMap
MethodMap.AmbiguousException
Simple distinguishable exception, used when we run across ambiguous overloading.
SecureIntrospectorControl
Interface used to determine which methods are allowed to be executed.
SecureIntrospectorImpl
Prevent "dangerous" classloader/reflection related calls.
SecureUberspector
Use a custom introspector that prevents classloader related method calls.
TypeConversionHandler
A conversion handler adds admissible conversions between Java types whenever Velocity introspection has to map VTL methods and property accessors to Java methods.
TypeConversionHandlerImpl
A conversion handler adds admissible conversions between Java types whenever Velocity introspection has to map VTL methods and property accessors to Java methods.
Uberspect
'Federated' introspection/reflection interface to allow the introspection behavior in Velocity to be customized.
UberspectImpl
Implementation of Uberspect to provide the default introspective functionality of Velocity
UberspectImpl.VelGetterImpl
UberspectImpl.VelMethodImpl
Implementation of VelMethod
UberspectImpl.VelSetterImpl
UberspectPublicFields
Implementation of Uberspect to additionally provide access to public fields.
VelMethod
Method used for regular method invocation $foo.bar()
VelPropertyGet
Interface defining a 'getter'.
VelPropertySet
Interface used for setting values that appear to be properties in Velocity.
