All Implemented Interfaces:

com.oracle.truffle.api.instrumentation.InstrumentableNode, com.oracle.truffle.api.nodes.NodeInterface, Cloneable

Direct Known Subclasses:

SLBigIntegerLiteralNode, SLBinaryNode, SLBuiltinAstNode, SLFunctionBodyNode, SLFunctionLiteralNode, SLInvokeNode, SLLogicalNotNode, SLLongLiteralNode, SLParenExpressionNode, SLReadArgumentNode, SLReadLocalVariableNode, SLReadPropertyNode, SLShortCircuitNode, SLStringLiteralNode, SLToBooleanNode, SLUnboxNode, SLWriteLocalVariableNode, SLWritePropertyNode

public abstract class SLExpressionNode
extends SLStatementNode

Base class for all SL nodes that produce a value and therefore benefit from type specialization. The annotation TypeSystemReference specifies the SL types. Specifying it here defines the type system for all subclasses.

Constructor Details

SLExpressionNode

public SLExpressionNode()

Method Details

executeGeneric

public abstract Object executeGeneric(com.oracle.truffle.api.frame.VirtualFrame frame)

The execute method when no specialization is possible. This is the most general case, therefore it must be provided by all subclasses.

executeVoid

public void executeVoid(com.oracle.truffle.api.frame.VirtualFrame frame)

When we use an expression at places where a statement is already sufficient, the return value is just discarded.

Specified by:

executeVoid in class SLStatementNode

createWrapper

public com.oracle.truffle.api.instrumentation.InstrumentableNode.WrapperNode createWrapper(com.oracle.truffle.api.instrumentation.ProbeNode probe)

Specified by:

createWrapper in interface com.oracle.truffle.api.instrumentation.InstrumentableNode

Overrides:

createWrapper in class SLStatementNode

hasTag

public boolean hasTag(Class<? extends com.oracle.truffle.api.instrumentation.Tag> tag)

Specified by:

hasTag in interface com.oracle.truffle.api.instrumentation.InstrumentableNode

Overrides:

hasTag in class SLStatementNode

addExpressionTag

public final void addExpressionTag()

Marks this node as being a StandardTags.ExpressionTag for instrumentation purposes.

executeLong

public long executeLong(com.oracle.truffle.api.frame.VirtualFrame frame)
                 throws com.oracle.truffle.api.nodes.UnexpectedResultException

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException

executeBoolean

public boolean executeBoolean(com.oracle.truffle.api.frame.VirtualFrame frame)
                       throws com.oracle.truffle.api.nodes.UnexpectedResultException

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException
