public abstract class PgParserAbstract extends ParserAbstract<PgDatabase>
Abstract base class for PostgreSQL statement parsers that provides common operations and utilities for parsing PostgreSQL database objects.

This class extends ParserAbstract to handle PostgreSQL-specific parsing operations such as column definitions, data types, operators, and other database constructs specific to PostgreSQL syntax.

  • Method Details

    • unquoteQuotedString

      public static Pair<String,org.antlr.v4.runtime.Token> unquoteQuotedString(SQLParser.SconstContext ctx)
      Unquotes a string constant from a parser context and returns both the unquoted string and the corresponding token.
      Parameters:
      ctx - the string constant context to unquote
      Returns:
      a pair containing the unquoted string and its token

    • getIdentifiers

      public static List<org.antlr.v4.runtime.ParserRuleContext> getIdentifiers(SQLParser.Schema_qualified_nameContext qNameCtx)
      Extracts identifier contexts from a schema-qualified name context.
      Parameters:
      qNameCtx - the schema-qualified name context
      Returns:
      a list of parser rule contexts representing the identifiers

    • getIdentifiers

      public static List<org.antlr.v4.runtime.ParserRuleContext> getIdentifiers(SQLParser.Schema_qualified_name_nontypeContext qNameNonTypeCtx)
      Extracts identifier contexts from a schema-qualified non-type name context.
      Parameters:
      qNameNonTypeCtx - the schema-qualified non-type name context
      Returns:
      a list of parser rule contexts representing the identifiers

    • getIdentifiers

      public static List<org.antlr.v4.runtime.ParserRuleContext> getIdentifiers(SQLParser.Operator_nameContext operQNameCtx)
      Extracts identifier contexts from an operator name context.
      Parameters:
      operQNameCtx - the operator name context
      Returns:
      a list of parser rule contexts representing the operator identifiers

    • getTypeName

      public static String getTypeName(SQLParser.Data_typeContext datatype)
      Extracts the normalized type name from a data type context, converting PostgreSQL type aliases to their canonical forms.
      Parameters:
      datatype - the data type context
      Returns:
      the normalized type name string

    • parseOperatorSignature

      public static String parseOperatorSignature(String name, SQLParser.Operator_argsContext operatorArgsCtx)
      Parses an operator signature from the operator name and arguments context.
      Parameters:
      name - the operator name
      operatorArgsCtx - the operator arguments context
      Returns:
      the formatted operator signature string

    • parseArguments

      public String parseArguments(SQLParser.Function_argsContext argsContext)
      Parses function arguments from the function arguments context.
      Parameters:
      argsContext - the function arguments context
      Returns:
      the formatted arguments string

    • parseSignature

      public static String parseSignature(String name, SQLParser.Function_argsContext argsContext)
      Parses a function signature from the function name and arguments context.
      Parameters:
      name - the function name (can be null for unnamed functions)
      argsContext - the function arguments context
      Returns:
      the formatted function signature string
