Enclosing class:

RecomputeFieldValue

public static interface RecomputeFieldValue.CustomFieldValueComputer

Custom recomputation of field values. A class implementing this interface must have a no-argument constructor, which is used to instantiate it before invoking RecomputeFieldValue.CustomFieldValueComputer.compute(jdk.vm.ci.meta.MetaAccessProvider, jdk.vm.ci.meta.ResolvedJavaField, jdk.vm.ci.meta.ResolvedJavaField, java.lang.Object).

Method Summary

Modifier and Type	Method and Description
Object	compute(jdk.vm.ci.meta.MetaAccessProvider metaAccess, jdk.vm.ci.meta.ResolvedJavaField original, jdk.vm.ci.meta.ResolvedJavaField annotated, Object receiver) Computes the new field value.

Method Detail

compute

Object compute(jdk.vm.ci.meta.MetaAccessProvider metaAccess,
               jdk.vm.ci.meta.ResolvedJavaField original,
               jdk.vm.ci.meta.ResolvedJavaField annotated,
               Object receiver)

Computes the new field value. This method can already be invoked during the analysis, especially when it computes the value of an object field that needs to be visited.

Parameters:

metaAccess - The AnalysisMetaAccess instance during the analysis or HostedMetaAccess instance after the analysis.

original - The original field (if RecomputeFieldValue is used for an Alias field).

annotated - The field annotated with RecomputeFieldValue.

receiver - The original object for instance fields, or null for static fields.

Returns:

The new field value.
