Class SLStatementNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.sl.nodes.local.SLScopedNode

com.oracle.truffle.sl.nodes.SLStatementNode

All Implemented Interfaces:

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

Direct Known Subclasses:

SLBlockNode, SLBreakNode, SLContinueNode, SLDebuggerNode, SLExpressionNode, SLIfNode, SLReturnNode, SLWhileNode

public abstract class SLStatementNode
extends SLScopedNode
implements com.oracle.truffle.api.instrumentation.InstrumentableNode

The base class of all Truffle nodes for SL. All nodes (even expressions) can be used as statements, i.e., without returning a value. The VirtualFrame provides access to the local variables.

Method Detail

getSourceSection

public final com.oracle.truffle.api.source.SourceSection getSourceSection()

Overrides:

getSourceSection in class com.oracle.truffle.api.nodes.Node

hasSource

public final boolean hasSource()

isInstrumentable

public final boolean isInstrumentable()

Specified by:

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

getSourceCharIndex

public final int getSourceCharIndex()

getSourceEndIndex

public final int getSourceEndIndex()

getSourceLength

public final int getSourceLength()

                                   int length)

setUnavailableSourceSection

public final void setUnavailableSourceSection()

hasTag

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

Specified by:

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

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

executeVoid

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

Execute this node as as statement, where no return value is necessary.

addStatementTag

public final void addStatementTag()

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

addRootTag

public final void addRootTag()

Marks this node as being a StandardTags.RootTag and StandardTags.RootBodyTag for instrumentation purposes.

toString

public String toString()

Overrides:

toString in class com.oracle.truffle.api.nodes.Node

formatSourceSection

public static String formatSourceSection(com.oracle.truffle.api.nodes.Node node)

Formats a source section of a node in human readable form. If no source section could be found it looks up the parent hierarchy until it finds a source section. Nodes where this was required append a '~' at the end.

Parameters:

node - the node to format.

Returns:

a formatted source section string
