Examples with DataIdentifierContext org.apache.sysml.parser.pydml.PydmlParser.DataIdentifierContext used on opensource projects

Example 1 with DataIdentifierContext

use of org.apache.sysml.parser.pydml.PydmlParser.DataIdentifierContext in project incubator-systemml by apache.

the class PydmlSyntacticValidator method exitFunctionCallMultiAssignmentStatement.

@Override
public void exitFunctionCallMultiAssignmentStatement(FunctionCallMultiAssignmentStatementContext ctx) {
    String[] names = getQualifiedNames(ctx.name.getText());
    if (names == null) {
        notifyErrorListeners("incorrect function name (only namespace.functionName allowed. Hint: If you are trying to use builtin functions, you can skip the namespace)", ctx.name);
        return;
    }
    String namespace = names[0];
    String functionName = names[1];
    ArrayList<ParameterExpression> paramExpression = getParameterExpressionList(ctx.paramExprs);
