Method Details
-
getStatementType
Description copied from interface:IStatementGets the type of this database object.- Returns:
- the database object type
-
getSchema
Gets the schema where this extension is installed.- Returns:
- schema name or null if using default
-
setSchema
-
setRelocatable
public void setRelocatable(boolean relocatable) -
getDatabase
Description copied from interface:IStatementGets the database that contains this statement.- Returns:
- the containing database
-
getCreationSQL
Description copied from class:PgStatementGenerates 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:
getCreationSQLin classPgStatement- Parameters:
script- the SQL script to append creation statements to
-
appendAlterSQL
Description copied from class:PgStatementFill script with object changes and return change type- Specified by:
appendAlterSQLin classPgStatement- Parameters:
newCondition- new object statescript- script to collect changes- Returns:
- object change type
-
compare
Description copied from class:PgStatementThis method does not account for nested child PgStatements. Shallow version ofPgStatement.equals(Object)- Overrides:
comparein classPgStatement
-
computeHash
Description copied from interface:IHashableComputes the hash of the implementing object using the provided hasher. The implementation should call appropriateputmethods on the hasher for all fields that should contribute to the hash value.- Parameters:
hasher- the hasher instance to use for hash computation
-
shallowCopy
Description copied from class:PgStatementCopies all object properties into a new object and leaves all its children empty.- Specified by:
shallowCopyin classPgStatement- Returns:
- shallow copy of a DB object.
