Method Detail

values

public static MethodVariableAccess[] 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 (MethodVariableAccess c : MethodVariableAccess.values())
    System.out.println(c);

Returns:

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

valueOf

public static MethodVariableAccess 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

forType

public static MethodVariableAccess forType(TypeDescription typeDescription)

Locates the correct accessor for a variable of a given type.

Parameters:

typeDescription - The type of the variable to be loaded.

Returns:

An accessor for the given type.

loadThisAndArguments

public static StackManipulation loadThisAndArguments(MethodDescription methodDescription)

Loads all method parameters for a given method, including a reference to the object instance if the method is not static.

Parameters:

methodDescription - The method for which all parameters and an instance reference, if any, is to be loaded.

Returns:

A stack manipulation representing the loading of all parameters including a reference to the instance if any.

loadArguments

public static StackManipulation loadArguments(MethodDescription methodDescription)

loadFromIndex

public StackManipulation loadFromIndex(int variableOffset)

Creates a stack assignment for a given index of the local variable array.

The index has to be relative to the method's local variable array size.

Parameters:

variableOffset - The offset of the variable where double and long types count two slots.

Returns:

A stack manipulation representing the method retrieval.
