    Methods in adql.db with parameters of type UnresolvedIdentifiersException
    Modifier and Type | Method | Description
    --- | --- | ---
    `protected void` | DBChecker.`checkCoordinateSystem​(STCS.CoordSys coordSys, ADQLOperand operand, UnresolvedIdentifiersException errors)` | Check whether the given coordinate system is allowed by this implementation.
    `protected void` | DBChecker.`checkCoordinateSystem​(StringConstant adqlCoordSys, UnresolvedIdentifiersException errors)` | Parse and then check the coordinate system contained in the given `StringConstant` instance.
    `protected SearchColumnList` | DBChecker.`checkDBItems​(ADQLQuery query, java.util.Stack<SearchColumnList> fathersList, UnresolvedIdentifiersException errors)` | Check DB items (tables and columns) used in the given ADQL query.
    `protected void` | DBChecker.`checkGeometries​(ADQLQuery query, UnresolvedIdentifiersException errors)` | Check all geometries.
    `protected void` | DBChecker.`checkGeometryFunction​(java.lang.String fctName, ADQLFunction fct, DBChecker.BinarySearch<java.lang.String,​java.lang.String> binSearch, UnresolvedIdentifiersException errors)` | Check whether the specified geometrical function is allowed by this implementation.
    `protected void` | DBChecker.`checkRegion​(STCS.Region r, RegionFunction fct, DBChecker.BinarySearch<java.lang.String,​java.lang.String> binSearch, UnresolvedIdentifiersException errors)` | Check the given region.
    `protected void` | DBChecker.`checkSubQueries​(ADQLQuery query, java.util.Stack<SearchColumnList> fathersList, SearchColumnList availableColumns, UnresolvedIdentifiersException errors)` | Search all sub-queries found in the given query but not in the clause FROM.
    `protected void` | DBChecker.`checkTypes​(ADQLQuery query, UnresolvedIdentifiersException errors)` | Search all operands whose the type is not yet known and try to resolve it now and to check whether it matches the type expected by the syntactic parser.
    `protected void` | DBChecker.`checkUDFs​(ADQLQuery query, UnresolvedIdentifiersException errors)` | Search all UDFs (User Defined Functions) inside the given query, and then check their signature against the list of allowed UDFs.
    `protected void` | DBChecker.`resolveColumns​(ADQLQuery query, java.util.Stack<SearchColumnList> fathersList, java.util.Map<DBTable,​ADQLTable> mapTables, SearchColumnList list, UnresolvedIdentifiersException errors)` | Search all column references inside the given query, resolve them thanks to the given tables' metadata, and if there is only one match, attach the matching metadata to them.
    `protected void` | DBChecker.`resolveCoordinateSystems​(ADQLQuery query, UnresolvedIdentifiersException errors)` | Search all explicit coordinate system declarations, check their syntax and whether they are allowed by this implementation.
    `protected void` | DBChecker.`resolveGeometryFunctions​(ADQLQuery query, DBChecker.BinarySearch<java.lang.String,​java.lang.String> binSearch, UnresolvedIdentifiersException errors)` | Search for all geometrical functions and check whether they are allowed.
    `protected void` | DBChecker.`resolveSTCSExpressions​(ADQLQuery query, DBChecker.BinarySearch<java.lang.String,​java.lang.String> binSearch, UnresolvedIdentifiersException errors)` | Search all STC-S expressions inside the given query, parse them (and so check their syntax) and then determine whether the declared coordinate system and the expressed region are allowed in this implementation.
    `protected java.util.Map<DBTable,​ADQLTable>` | DBChecker.`resolveTables​(ADQLQuery query, java.util.Stack<SearchColumnList> fathersList, UnresolvedIdentifiersException errors)` | Search all table references inside the given query, resolve them against the available tables, and if there is only one match, attach the matching metadata to them.
