isStatic

public boolean isStatic()

Description copied from interface: IAttributedFeatureInfo

True if this feature is static, meaning the feature is not specific to a particular instance of the feature's containing type.

Specified by:

isPrivate

public boolean isPrivate()

Description copied from interface: IAttributedFeatureInfo

True if this feature is private. Private features are only accessible from within the type that owns them.

Specified by:

public boolean isProtected()

Description copied from interface: IAttributedFeatureInfo

True if this feature is protected. Protected features are accessible from within the type that owns them and from derived containers.

Specified by:

isProtected in interface IAttributedFeatureInfo

Overrides:

isProtected in class BaseFeatureInfo

isPublic

public boolean isPublic()

Description copied from interface: IAttributedFeatureInfo

True if this feature is public. Public features are not restricted.

Specified by:

Overrides:

isPublic in class BaseFeatureInfo

isAbstract

public boolean isAbstract()

Specified by:

getGosuAnnotations

protected java.util.List<IGosuAnnotation> getGosuAnnotations()

Specified by:

getGosuAnnotations in class GosuBaseAttributedFeatureInfo

isReadable

public boolean isReadable()

Specified by:

isReadable in interface IPropertyInfo

Returns:

true if the property is readable given the visibility constraint passed in, false otherwise.

isReadable

public boolean isReadable(IType whosAskin)

Specified by:

isReadable in interface IPropertyInfo

isWritable

public boolean isWritable()

Specified by:

isWritable in interface IPropertyInfo

Returns:

True if the property is writable given the visibility constraint passed in, false otherwise.

isWritable

public boolean isWritable(IType whosAskin)

Specified by:

isWritable in interface IPropertyInfo

Parameters:

whosAskin - The type querying the property writability. For example, passing in the type the property is on will allow properties that have private access in the setter to be written to. Passing in an unrelated type will only allow properties that are to be written to.

Returns:

True if the property is writable given the visibility constraint passed in, false otherwise.

isAccessible

public boolean isAccessible(IType whosAskin,
                            ReducedDynamicFunctionSymbol accessor)

getAccessor

public IPropertyAccessor getAccessor()

Specified by:

getAccessor in interface IPropertyInfo

Returns:

the PropertyAccessor (for getting and setting) this property.

getPresentationInfo

public IPresentationInfo getPresentationInfo()

Specified by:

getPresentationInfo in interface IPropertyInfo

getGosuClass

IGosuClassInternal getGosuClass()

getFeatureType

public IType getFeatureType()

Description copied from interface: IIntrinsicTypeReference

The type of this feature e.g., for a property this is the property's type.

Specified by:

getFeatureType in interface IIntrinsicTypeReference

getAssignableFeatureType

public IType getAssignableFeatureType()

Description copied from interface: IIntrinsicTypeReference

The type this feature can be assigned from. Most of the time this is the same type as getFeatureType(), however it can be different and when it is it should almost always be contravariant with getFeatureType().

A property setter method is the primary use-case. For instance:

   interface Foo {
     property Name: CharSequence
   }

   class FooImpl implements Foo {
     var _name: String
     override property get Name(): String {
       return _name
     }
     override property set Name( cs: CharSequence ) {
       _name = cs.toString()
     }
   }
 

Here FooImpl overrides Foo's Name property with covariance on the getter's return type. This establishes that Name wrt FooImpl is of type String. Yet Foo's setter method must be overridden as-is, a method cannot override another method with covariant parameters. So, in terms of FooImpl's Name property, the setter method is contravariant with String, which again is Name's type wrt of FooImpl. Therefore, FooImpl's Name property should implement getAssignableFeatureType() and return CharSequence.

getAssignableFeatureType in interface IIntrinsicTypeReference

public ReducedDynamicPropertySymbol getDps()

Specified by:

getDps in interface IGosuPropertyInfo

getContainingType

An array of generic type variables if this feature corresponds with a generic type.

getParameterizedReturnType

inferTypeParametersFromArgumentTypes

public TypeVarToTypeMap inferTypeParametersFromArgumentTypes(IType... argTypes)

Specified by:

inferTypeParametersFromArgumentTypes in interface IGenericMethodInfo

Parameters:

argTypes - The argument types from a generic method call.

Returns:

A map of inferred type parameters based on the argTypes. The map contains only the types that could be inferred -- the map may be empty.

E.g., given generic method: T[] toArray( T[] ) and call: list.toArray( new String[list.size()] ); => the toArray() method call should be automatically parameterized with based on the new String[0].
