Method Detail

initWriteSlotNode

public TypeNode initWriteSlotNode(int slot)

Description copied from class: TypeNode

Initializes this node's frame slot. Called if this node is a function/method parameter type. Kept separate from constructor so that TypeNode.TypeAliasTypeNode can initialize frame slot of its cloned child node.

Specified by:

initWriteSlotNode in class TypeNode

execute

public void execute(com.oracle.truffle.api.frame.VirtualFrame frame,
                    java.lang.Object value)

Description copied from class: TypeNode

Checks if `value` conforms to this type. If so, returns normally. Otherwise, throws a `VmTypeMismatchException`.

Specified by:

execute in class TypeNode

executeAndSet

public void executeAndSet(com.oracle.truffle.api.frame.VirtualFrame frame,
                          java.lang.Object value)

Description copied from class: TypeNode

Checks if `value` conforms to this type. If so, sets `slot` to `value`. Otherwise, throws a `VmTypeMismatchException`.

Specified by:

executeAndSet in class TypeNode

getFrameSlotKind

public com.oracle.truffle.api.frame.FrameSlotKind getFrameSlotKind()

Specified by:

getFrameSlotKind in class TypeNode

getMirror

public VmTyped getMirror()

Overrides:

getMirror in class TypeNode

doExport

protected PType doExport()

Overrides:

doExport in class TypeNode
