public ForFieldAccess(TypeDescription instrumentedType,
 MemberSubstitution.Substitution.ForFieldAccess.FieldResolver fieldResolver)

Creates a new substitution with a field access.

Parameters:

instrumentedType - The instrumented type.

fieldResolver - A resolver to locate the field to access.

Method Details

resolve

public StackManipulation resolve(TypeDescription receiver,
 ByteCodeElement.Member original,
 TypeList.Generic parameters,
 TypeDescription.Generic result,
 JavaConstant.MethodHandle methodHandle,
 StackManipulation stackManipulation,
 int freeOffset)

Resolves this substitution into a stack manipulation.

Specified by:

resolve in interface MemberSubstitution.Substitution

Parameters:

receiver - The target type on which a member is accessed.

original - The field, method or constructor that is substituted.

parameters - All parameters that serve as input to this access.

result - The result that is expected from the interaction or void if no result is expected.
