Constructor Detail

ForStackManipulation

public ForStackManipulation(StackManipulation stackManipulation,
                            java.lang.reflect.Type type)

Creates an argument loader that loads a stack manipulation as an argument.

Parameters:

stackManipulation - The stack manipulation to load.

type - The type of the resulting value.

ForStackManipulation

public ForStackManipulation(StackManipulation stackManipulation,
                            TypeDefinition typeDefinition)

Creates an argument loader that loads a stack manipulation as an argument.

Parameters:

stackManipulation - The stack manipulation to load.

typeDefinition - The type of the resulting value.

Method Detail

of

public static MethodCall.ArgumentLoader.Factory of(java.lang.Object value)

Creates an argument loader that loads the supplied value as a constant. If the value cannot be represented in the constant pool, a field is created to store the value.

Parameters:

value - The value to load as an argument or null.

Returns:

An appropriate argument loader.

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Prepares a given instrumented type.

Specified by:

prepare in interface InstrumentedType.Prepareable

Parameters:

instrumentedType - The instrumented type in its current form.

Returns:

The prepared instrumented type.

make

public MethodCall.ArgumentLoader.ArgumentProvider make(Implementation.Target implementationTarget)

Creates an argument provider for the supplied implementation target.

Specified by:

make in interface MethodCall.ArgumentLoader.Factory

Parameters:

implementationTarget - The implementation target to use.

Returns:

An appropriate argument provider.

resolve

public java.util.List<MethodCall.ArgumentLoader> resolve(MethodDescription instrumentedMethod,
                                                         MethodDescription invokedMethod)

Resolves this provider to an argument loader for each provided argument.

Specified by:

resolve in interface MethodCall.ArgumentLoader.ArgumentProvider

Parameters:

instrumentedMethod - The instrumented method.

invokedMethod - The invoked method.

Returns:

A list of provided argument loaders.

toStackManipulation

public StackManipulation toStackManipulation(ParameterDescription target,
                                             Assigner assigner,
                                             Assigner.Typing typing)

Loads the argument that is represented by this instance onto the operand stack.

Specified by:

toStackManipulation in interface MethodCall.ArgumentLoader

Parameters:

target - The target parameter.

assigner - The assigner to be used.

typing - Indicates if dynamic type castings should be attempted for incompatible assignments.

Returns:

The stack manipulation that loads the represented argument onto the stack.
