MatchContext

public MatchContext(NodeLIRBuilder builder,
                    MatchStatement rule,
                    int index,
                    Node node,

Method Detail

getRoot

public Node getRoot()

captureNamedValue

public org.graalvm.compiler.core.match.MatchPattern.Result captureNamedValue(String name,
                                                                             Class<? extends Node> type,

validate

public org.graalvm.compiler.core.match.MatchPattern.Result validate()

setResult

public void setResult(ComplexMatchResult result)

Mark the interior nodes with INTERIOR_MATCH and set the Value of the root to be the result. During final LIR generation it will be evaluated to produce the actual LIR value.

Parameters:

result -

consume

public org.graalvm.compiler.core.match.MatchPattern.Result consume(Node node,
                                                                   boolean ignoresSideEffects,
                                                                   boolean atRoot,
                                                                   boolean singleUser)

Mark a node as consumed by the match. Consumed nodes will never be evaluated.

Returns:

Result.OK if the node can be safely consumed.

namedNode

public Node namedNode(String name)

Return the named node. It's an error if the

Parameters:

name - the name of a node in the match rule

Returns:

the matched node

Throws:

GraalError - is the named node doesn't exist.

toString

public String toString()

Overrides:

toString in class Object
