All Implemented Interfaces:

Serializable, Comparable<MemberSubstitution.Substitution.Stubbing>, MemberSubstitution.Substitution<MemberSubstitution.Target>, MemberSubstitution.Substitution.Factory<MemberSubstitution.Target>

Enclosing interface:

MemberSubstitution.Substitution<T extends MemberSubstitution.Target>

public static enum MemberSubstitution.Substitution.Stubbing
extends Enum<MemberSubstitution.Substitution.Stubbing>
implements MemberSubstitution.Substitution<MemberSubstitution.Target>, MemberSubstitution.Substitution.Factory<MemberSubstitution.Target>

A substitution that drops any field or method access and returns the expected return type's default value, i.e null or zero for primitive types.

Enum Constant Detail

INSTANCE

public static final MemberSubstitution.Substitution.Stubbing INSTANCE

The singleton instance.

Method Detail

values

public static MemberSubstitution.Substitution.Stubbing[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MemberSubstitution.Substitution.Stubbing c : MemberSubstitution.Substitution.Stubbing.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MemberSubstitution.Substitution.Stubbing valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

make

public MemberSubstitution.Substitution<MemberSubstitution.Target> make(TypeDescription instrumentedType,
                                                                       MethodDescription instrumentedMethod,
                                                                       TypePool typePool)

Creates a substitution for an instrumented method.

Specified by:

make in interface MemberSubstitution.Substitution.Factory<MemberSubstitution.Target>

Parameters:

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

typePool - The type pool being used.

Returns:

The substitution to apply within the instrumented method.

resolve

public StackManipulation resolve(MemberSubstitution.Target target,
                                 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<MemberSubstitution.Target>

Parameters:

target - The targeted member 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.

methodHandle - A method handle describing the substituted expression.

stackManipulation - The original byte code expression that is being executed.

freeOffset - The first free offset of the local variable array that can be used for storing values.

Returns:

A stack manipulation that represents the access.
