public class PgOperator extends PgAbstractStatement implements IOperator, ISearchPath
PostgreSQL operator implementation. Operators are symbols that represent specific operations (like +, -, *, etc.) and can be customized for user-defined types with associated functions.

  • Constructor Details

      public PgOperator(String name)
      Creates a new PostgreSQL operator.
      Parameters:
      name - operator symbol

    • getCreationSQL

      public void getCreationSQL(SQLScript script)
      Description copied from interface: IStatement
      Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.
      Specified by:
      getCreationSQL in interface IStatement
      Parameters:
      script - the SQL script to append creation statements to

    • appendAlterSQL

      public ObjectState appendAlterSQL(IStatement newCondition, SQLScript script)
      Description copied from interface: IStatement
      Fill script with object changes and return change type
      Specified by:
      appendAlterSQL in interface IStatement
      Parameters:
      newCondition - new object state
      script - script to collect changes
      Returns:
      object change type

    • setReturns

      public void setReturns(String returns)
      Description copied from interface: IOperator
      Sets the return type of this operator.
      Specified by:
      setReturns in interface IOperator
      Parameters:
      returns - the return type to set

    • getReturns

      public String getReturns()
      Description copied from interface: IOperator
      Gets the return type of this operator.
      Specified by:
      getReturns in interface IOperator
      Returns:
      the return type

    • getSignature

      public String getSignature()
      Returns the operator signature including its arguments.
      Returns:
      operator signature in format "op(leftarg, rightarg)"

    • getArguments

      public String getArguments()
      Returns the operator arguments in parentheses format.
      Returns:
      arguments string in format "(leftarg, rightarg)" or "(rightarg)" for unary

    • getName

      public String getName()
      Alias for getSignature() which provides a unique operator ID.

      Use AbstractStatement.getBareName() to get just the operator name.

      Specified by:
      getName in interface IStatement
      Overrides:
      getName in class AbstractStatement
      Returns:
      the statement name

      Specified by:
      getQualifiedName in interface IStatement
      Overrides:
      getQualifiedName in class AbstractStatement
      Returns:
      fully qualified (up to schema) dot-delimited object name. Identifiers are quoted.

    • getLeftArg

      public String getLeftArg()
      Description copied from interface: IOperator
      Gets the left argument type of this operator.
