Method Detail

extendsType

boolean extendsType(org.springframework.roo.model.JavaType type)

Indicates whether this type extends the given type. Equivalent to calling getExtendsTypes() and checking whether the given type is in the returned list.

Parameters:

type - the supertype being checked for (required)

Returns:

see above

getDeclaredConstructor

ConstructorMetadata getDeclaredConstructor(List<org.springframework.roo.model.JavaType> parameters)

Locates the constructor with the specified parameter types.

Parameters:

parameters - to locate (can be null if there are no parameters)

Returns:

the constructor, or null if not found

Since:

1.2.0

getDeclaredConstructors

List<? extends ConstructorMetadata> getDeclaredConstructors()

getDeclaredField

FieldMetadata getDeclaredField(org.springframework.roo.model.JavaSymbolName fieldName)

Locates the specified field.

Parameters:

fieldName - to locate (can be null)

Returns:

the field, or null if not found

Since:

1.2.0

getDeclaredFields

List<? extends FieldMetadata> getDeclaredFields()

getDeclaredInitializers

List<? extends InitializerMetadata> getDeclaredInitializers()

getDeclaredInnerType

ClassOrInterfaceTypeDetails getDeclaredInnerType(org.springframework.roo.model.JavaType typeName)

Locates an inner type with the specified name.

Parameters:

typeName - to locate (required)

Since:

1.2.0

getDeclaredInnerTypes

List<ClassOrInterfaceTypeDetails> getDeclaredInnerTypes()

getDeclaredMethods

List<? extends MethodMetadata> getDeclaredMethods()

getDynamicFinderNames

List<String> getDynamicFinderNames()

Returns the names of any dynamic finders

Returns:

a non-null list

Since:

1.2.0

getExtendsTypes

List<org.springframework.roo.model.JavaType> getExtendsTypes()

Lists the classes this type extends. This may be empty. Always empty in the case of an enum.

While a List is used, normally in Java a class will only extend a single other class. A List is used to support interfaces, as well as support the special "declare parents: DestinationType extends SuperclassType" feature of ITDs which permits effectively multiple inheritance.

Returns:

an unmodifiable representation of classes this type extends (may be empty, but never null)

getField

FieldMetadata getField(org.springframework.roo.model.JavaSymbolName fieldName)

Searches up the inheritance hierarchy until the first field with the specified name is located.

Parameters:

fieldName - to locate (required)

Returns:

the field, or null if not found

Since:

1.2.0

getFieldsWithAnnotation

List<FieldMetadata> getFieldsWithAnnotation(org.springframework.roo.model.JavaType annotation)

Searches up the inheritance hierarchy and locates all declared fields which are annotated with the specified annotation.

Parameters:

annotation - to locate (required)

Returns:

all the located fields (never null, but may be empty)

Since:

1.2.0

getImplementsTypes

List<org.springframework.roo.model.JavaType> getImplementsTypes()

Lists the classes this type implements. Always empty in the case of an interface.

A List is used to support interfaces, as well as support the special "declare parents: DestinationType implements SomeInterfaceType" feature of ITDs.

Returns:

an unmodifiable representation of classes this type implements (may be empty, but never null)

getLayerEntities

List<org.springframework.roo.model.JavaType> getLayerEntities()

If this is a layering component, for example a service or repository, returns the domain entities managed by this component, otherwise returns an empty list.

Returns:

a non-null list (may be empty)

Since:

1.2.0

getMethod

MethodMetadata getMethod(org.springframework.roo.model.JavaSymbolName methodName)

Searches up the inheritance hierarchy until the first method with the specified name is located; method parameters are not taken into account.

Parameters:

methodName - to locate (required)

Returns:

the method, or null if not found

Since:

1.2.0

getMethod

MethodMetadata getMethod(org.springframework.roo.model.JavaSymbolName methodName,
                         List<org.springframework.roo.model.JavaType> parameters)

Searches up the inheritance hierarchy until the first method with the specified name and parameters is located.

Parameters:

methodName - to locate (required)

parameters - to locate (can be null if there are no parameters)

Returns:

the method, or null if not found

Since:

1.2.0

getMethods

List<MethodMetadata> getMethods()

Locates all methods on this class and its superclasses.

Returns:

zero or more methods (never null)

getUniqueFieldName

org.springframework.roo.model.JavaSymbolName getUniqueFieldName(String proposedName)

Generates a unique name for a field, starting from the given proposed name and adding underscores until it's unique.

Parameters:

proposedName - the proposed field name (required)

Returns:

a non-null name that's unique within the governor

Since:

1.2.0

implementsAny

boolean implementsAny(org.springframework.roo.model.JavaType... type)

Indicates whether this type implements the given types. Equivalent to calling getImplementsTypes() and checking whether the given types are in the returned list.

Parameters:

type - the interfaces being checked for (required)

Returns:

see above

implementsType

boolean implementsType(org.springframework.roo.model.JavaType interfaceType)

Indicates whether this type implements the given interface. Equivalent to calling getImplementsTypes() and checking whether the given type is in the returned list.

Parameters:

type - the interface being checked for (required)

Returns:

see above
