Method Details

executeVoid

void executeVoid(VirtualFrame frame,
 T node,
 int index,
 int argument)

Executes the block node element without expecting any return value.

Since:

19.3

executeGeneric

default Object executeGeneric(VirtualFrame frame,
 T node,
 int index,
 int argument)

Executes the block node element and expects a generic value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeVoid(VirtualFrame, Node, int, int) by default.

Since:

19.3

executeBoolean

default boolean executeBoolean(VirtualFrame frame,
 T node,
 int index,
 int argument)
                        throws UnexpectedResultException

Executes the block node element and expects a boolean value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not a boolean.

Throws:

UnexpectedResultException

Since:

19.3

executeByte

default byte executeByte(VirtualFrame frame,
 T node,
 int index,
 int argument)
                  throws UnexpectedResultException

Executes the block node element and expects a byte value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not a byte.

Throws:

UnexpectedResultException

Since:

19.3

executeShort

default short executeShort(VirtualFrame frame,
 T node,
 int index,
 int argument)
                    throws UnexpectedResultException

Executes the block node element and expects a short value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not a short.

Throws:

UnexpectedResultException

Since:

19.3

executeChar

default char executeChar(VirtualFrame frame,
 T node,
 int index,
 int argument)
                  throws UnexpectedResultException

Executes the block node element and expects a char value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not a char.

Throws:

UnexpectedResultException

Since:

19.3

executeInt

default int executeInt(VirtualFrame frame,
 T node,
 int index,
 int argument)
                throws UnexpectedResultException

Executes the block node element and expects an int value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not an int.

Throws:

UnexpectedResultException

Since:

19.3

executeLong

default long executeLong(VirtualFrame frame,
 T node,
 int index,
 int argument)
                  throws UnexpectedResultException

Executes the block node element and expects a long value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not a long.

Throws:

UnexpectedResultException

Since:

19.3

executeFloat

default float executeFloat(VirtualFrame frame,
 T node,
 int index,
 int argument)
                    throws UnexpectedResultException

Executes the block node element and expects a float value. This method is used for the last element of the block, to provide a value to the block execute method. Forwards to executeGeneric(VirtualFrame, Node, int, int) by default and throws an UnexpectedResultException if the value is not a float.

Throws:

UnexpectedResultException

Since:
