  • Method Details

    • 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
    • getDropSQL

      public void getDropSQL(SQLScript script, boolean optionExists)
      Description copied from interface: IStatement
      Generates DROP SQL for this statement.
      Specified by:
      getDropSQL in interface IStatement
      Overrides:
      getDropSQL in class AbstractStatement
      Parameters:
      script - the SQL script to append the DROP statement to
      optionExists - whether to include "IF EXISTS" in the DROP statement
    • setDisabled

      public void setDisabled(boolean isDisabled)
    • setNotValid

      public void setNotValid(boolean isNotValid)
    • getColumns

      public Collection<String> getColumns()
      Description copied from interface: IConstraint
      Gets the columns involved in this constraint.
      Specified by:
      getColumns in interface IConstraint
      Returns:
      a collection of column names
    • containsColumn

      public boolean containsColumn(String name)
      Description copied from interface: IConstraint
      Checks if this constraint involves the specified column.
      Specified by:
      containsColumn in interface IConstraint
      Parameters:
      name - the column name to check
      Returns:
      true if the column is part of this constraint
    • getTableName

      public String getTableName()
      Description copied from interface: IConstraint
      Gets the name of the table this constraint belongs to.
      Specified by:
      getTableName in interface IConstraint
      Returns:
      the table name
    • computeHash

      public void computeHash(Hasher hasher)
      Description copied from interface: IHashable
      Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.
      Specified by:
      computeHash in interface IHashable
      Parameters:
      hasher - the hasher instance to use for hash computation
    • compare

      public boolean compare(IStatement obj)
      Description copied from class: AbstractStatement
      This method does not account for nested child PgStatements. Shallow version of AbstractStatement.equals(Object)
      Specified by:
      compare in interface IStatement
      Overrides:
      compare in class AbstractStatement
