Examples with BLangXMLNS org.wso2.ballerinalang.compiler.tree.BLangXMLNS used on opensource projects

Example 1 with BLangXMLNS

use of org.wso2.ballerinalang.compiler.tree.BLangXMLNS in project ballerina by ballerina-lang.

the class SymbolEnter method createNamespaceDeclrStatement.

private BLangXMLNSStatement createNamespaceDeclrStatement(BLangXMLNS xmlns) {
    BLangXMLNSStatement xmlnsStmt = (BLangXMLNSStatement) TreeBuilder.createXMLNSDeclrStatementNode();
    xmlnsStmt.xmlnsDecl = xmlns;
    xmlnsStmt.pos = xmlns.pos;
    return xmlnsStmt;
}

Example 2 with BLangXMLNS

use of org.wso2.ballerinalang.compiler.tree.BLangXMLNS in project ballerina by ballerina-lang.

the class SymbolEnter method visit.

@Override
public void visit(BLangXMLNS xmlnsNode) {
    String nsURI = (String) ((BLangLiteral) xmlnsNode.namespaceURI).value;
    if (xmlnsNode.prefix.value != null && nsURI.isEmpty()) {
        dlog.error(xmlnsNode.pos, DiagnosticCode.INVALID_NAMESPACE_DECLARATION, xmlnsNode.prefix);
    }
    // set the prefix of the default namespace
    if (xmlnsNode.prefix.value == null) {
        xmlnsNode.prefix.value = XMLConstants.DEFAULT_NS_PREFIX;
    }
    BXMLNSSymbol xmlnsSymbol = Symbols.createXMLNSSymbol(names.fromIdNode(xmlnsNode.prefix), nsURI, env.enclPkg.symbol.pkgID, env.scope.owner);
    xmlnsNode.symbol = xmlnsSymbol;
    // First check for package-imports with the same alias.
    // Here we do not check for owner equality, since package import is always at the package
    // level, but the namespace declaration can be at any level.
    BSymbol foundSym = symResolver.lookupSymbol(env, xmlnsSymbol.name, SymTag.PACKAGE);
    if (foundSym != symTable.notFoundSymbol) {
        dlog.error(xmlnsNode.pos, DiagnosticCode.REDECLARED_SYMBOL, xmlnsSymbol.name);
        return;
    }
    // Define it in the enclosing scope. Here we check for the owner equality,
    // to support overriding of namespace declarations defined at package level.
    defineSymbol(xmlnsNode.pos, xmlnsSymbol);
}
