Constructor Detail

ConstructorInvokeNode

public ConstructorInvokeNode(ClassNode classNode,
                             List<Node> paramNodes)

Constructor.

Parameters:

classNode - class containing constructor

paramNodes - constructor parameters

Method Detail

evaluate

public Value evaluate(ParseSession session)

Description copied from interface: Node

Evaluate this node. There will be a transaction open.

Parameters:

session - parse session

Returns:

result of node evaluation

getType

public Class<?> getType(ParseSession session)

Description copied from interface: Node

Get the type of this node's value.

If the type is unknown, Object.class should be returned.

Parameters:

session - parse session

Returns:

the expected type of the node

evaluateParams

protected io.permazen.parse.expr.AbstractInvokeNode.ParamInfo evaluateParams(ParseSession session)

Evaluate parameters and parameter types.

TypeInferringNodes are not evaluated, instead they are left as null and the corresponding parameter type is set to the special value MethodUtil.FunctionalType. Null parameters have their parameter type set to MethodUtil.NullType.

Parameters:

session - parse session

Returns:

evaluated parameter info

fixupVarArgs

protected void fixupVarArgs(io.permazen.parse.expr.AbstractInvokeNode.ParamInfo paramInfo,
                            T executable)

fixupTypeInferringNodes

protected void fixupTypeInferringNodes(ParseSession session,
                                       io.permazen.parse.expr.AbstractInvokeNode.ParamInfo paramInfo,
                                       T executable)
