  • Method Details

    • getCreationSQL

      public void getCreationSQL(SQLScript script)
      Description copied from class: PgStatement
      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 class PgStatement
      Parameters:
      script - the SQL script to append creation statements to
    • appendAlterSQL

      public ObjectState appendAlterSQL(PgStatement newCondition, SQLScript script)
      Description copied from class: PgStatement
      Fill script with object changes and return change type
      Specified by:
      appendAlterSQL in class PgStatement
      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 class: PgStatement
      Generates DROP SQL for this statement.
      Overrides:
      getDropSQL in class PgStatement
      Parameters:
      script - the SQL script to append the DROP statement to
      optionExists - whether to include "IF EXISTS" in the DROP statement
    • compare

      public boolean compare(PgStatement obj)
      Description copied from class: PgStatement
      This method does not account for nested child PgStatements. Shallow version of PgStatement.equals(Object)
      Overrides:
      compare in class AbstractConstraint
    • setDisabled

      public void setDisabled(boolean isDisabled)
    • 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
      Overrides:
      computeHash in class AbstractConstraint
      Parameters:
      hasher - the hasher instance to use for hash computation
    • shallowCopy

      public AbstractConstraint shallowCopy()
      Description copied from class: PgStatement
      Copies all object properties into a new object and leaves all its children empty.
      Overrides:
      shallowCopy in class AbstractConstraint
      Returns:
      shallow copy of a DB object.
    • getDbType

      public DatabaseType getDbType()
      Overrides:
      getDbType in class PgStatement
