Package com.oracle.truffle.sl.nodes

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.

    • 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
