Enum Constant Details

POP_TOP

public static final StackOpDescriptor POP_TOP

Removes the top-of-stack (TOS) item.

ROT_TWO

public static final StackOpDescriptor ROT_TWO

Swaps the two top-most stack items.

ROT_THREE

public static final StackOpDescriptor ROT_THREE

Lifts second and third stack item one position up, moves top down to position three.

ROT_FOUR

public static final StackOpDescriptor ROT_FOUR

Lifts second, third and fourth stack items one position up, moves top down to position four.

COPY

public static final StackOpDescriptor COPY

Push the i-th item to the top of the stack. The item is not removed from its original location. Uses 1-based indexing (TOS is 1, TOS1 is 2, ...) instead of 0-based indexing.

SWAP

public static final StackOpDescriptor SWAP

Swap TOS with the item at position i. Uses 1-based indexing (TOS is 1, TOS1 is 2, ...) instead of 0-based indexing.

DUP_TOP

public static final StackOpDescriptor DUP_TOP

Duplicates the reference on top of the stack.

DUP_TOP_TWO

public static final StackOpDescriptor DUP_TOP_TWO

Duplicates the two references on top of the stack, leaving them in the same order.

Method Details

values

public static StackOpDescriptor[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static StackOpDescriptor valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getVersionMapping

public VersionMapping getVersionMapping()

Specified by:
