Method Detail

forObject

public JavaConstant forObject(Object object)

Description copied from interface: SnippetReflectionProvider

Creates a boxed object constant.

Specified by:

forObject in interface SnippetReflectionProvider

Parameters:

object - the object value to box

Returns:

a constant containing object

asObject

public Object asObject(ResolvedJavaType type,
                       JavaConstant constant)

Description copied from interface: SnippetReflectionProvider

Gets the object reference a given constant represents if it is of a given type. The constant must have kind Kind.Object.

Specified by:

asObject in interface SnippetReflectionProvider

Parameters:

type - the expected type of the object represented by constant. If the object is required to be of this type, then wrap the call to this method in Objects.requireNonNull(Object).

constant - an object constant

Returns:

the object value represented by constant if it is an instance of type otherwise null

asObject

public <T> T asObject(Class<T> type,
                      JavaConstant constant)

Description copied from interface: SnippetReflectionProvider

Gets the object reference a given constant represents if it is of a given type. The constant must have kind Kind.Object.

Specified by:

asObject in interface SnippetReflectionProvider

Parameters:

type - the expected type of the object represented by constant. If the object is required to be of this type, then wrap the call to this method in Objects.requireNonNull(Object).

constant - an object constant

Returns:

the object value represented by constant cast to type if it is an instance of type otherwise null

forBoxed

public JavaConstant forBoxed(Kind kind,
                             Object value)

Description copied from interface: SnippetReflectionProvider

Creates a boxed constant for the given kind from an Object. The object needs to be of the Java boxed type corresponding to the kind.

Specified by:

forBoxed in interface SnippetReflectionProvider

Parameters:

kind - the kind of the constant to create

value - the Java boxed value: a Byte instance for Kind.Byte, etc.

Returns:

the boxed copy of value

getSubstitutionGuardParameter

public Object getSubstitutionGuardParameter(Class<?> type)

Description copied from interface: SnippetReflectionProvider

Gets the value to bind to a parameter in a SubstitutionGuard constructor.

Specified by:

getSubstitutionGuardParameter in interface SnippetReflectionProvider

Parameters:

type - the type of a parameter in a SubstitutionGuard constructor

Returns:

the value that should be bound to the parameter when invoking the constructor or null if this provider cannot provide a value of the requested type

getInjectedNodeIntrinsicParameter

public Object getInjectedNodeIntrinsicParameter(ResolvedJavaType type)

Description copied from interface: SnippetReflectionProvider

Gets the value to bind to an injected parameter in a node intrinsic.

Specified by:

getInjectedNodeIntrinsicParameter in interface SnippetReflectionProvider

Parameters:

type - the type of a parameter in a node intrinsic constructor

Returns:

the value that should be bound to the parameter when invoking the constructor or null if this provider cannot provide a value of the requested type
