Class InlineSupport.InlineTarget

com.oracle.truffle.api.dsl.InlineSupport.InlineTarget

Enclosing class:

InlineSupport

public static final class InlineSupport.InlineTarget
extends Object

An inline targert for an inlinable node. This is used as first parameter of an inline method. The inline method is used by generated Truffle DSL code as well as manually written inlinable nodes. Usage example:

 public static InlinedCountingConditionProfile inline(
                 @RequiredField(value = StateField.class, bits = 7) //
                 @RequiredField(value = PrimitiveIntField.class) //
                 @RequiredField(value = ReferenceField.class, type = String.class) InlineTarget target) {
     StateField state = target.getState(0, 7);
     PrimitiveIntField primitive = target.getPrimitive(1, PrimitiveIntField.class);
     ReferenceField reference = target.getReference(2, String.class);

     // pass fields on to inline node
 }

Method Details

getTargetClass

public Class<?> getTargetClass()

Returns static target class this inlining specification was applied.

getPrimitive

public <T extends InlineSupport.InlinableField> T getPrimitive(int index,
 Class<T> fieldClass)

Requests a primitive field for a given field index. Fields that are requested from a target must match the required fields specified using InlineSupport.RequiredField on the target parameter of an inline method otherwise an IncompatibleClassChangeError is thrown.

Since:

23.0

getState

public InlineSupport.StateField getState(int index,
 int minimumBits)

Requests a state field for a given field index. Fields that are requested from a target must match the required fields specified using InlineSupport.RequiredField on the target parameter of an inline method otherwise an IncompatibleClassChangeError is thrown.

Since:

23.0

getReference

public <V> InlineSupport.ReferenceField<V> getReference(int index,
 Class<?> valueClass)

Requests a reference field for a given field index. Fields that are requested from a target must match the required fields specified using InlineSupport.RequiredField on the target parameter of an inline method otherwise an IncompatibleClassChangeError is thrown.

Since:

23.0

create

public static InlineSupport.InlineTarget create(Class<?> targetClass,
 InlineSupport.InlinableField... updaters)

Creates an inline target for an inlined node. Intended for use by generated code only.
