readConstantField

public <T> T readConstantField(ResolvedJavaField field,
                               ConstantFieldProvider.ConstantFieldTool<T> tool)

Description copied from interface: ConstantFieldProvider

Decide whether a read from the field should be constant folded. This should return ConstantFieldProvider.ConstantFieldTool.foldConstant(JavaConstant) or ConstantFieldProvider.ConstantFieldTool.foldStableArray(JavaConstant, int, boolean) if the read should be constant folded, or null otherwise.
