org.apache.derby.impl.sql.compile.NodeFactoryImpl
| NodeFactoryImpl | | public class NodeFactoryImpl extends NodeFactory implements ModuleControl,ModuleSupportable(Code) | | This class is a factory for QueryTreeNode nodes. It exists to provide
methods to generate new nodes without having to call new directly.
In the future, it may implement caching of nodes, as well, to avoid
memory management and garbage collection.

| public | NodeFactoryImpl()
Every Module needs a public niladic constructor. |
| Method Summary | |
| public void | boot(boolean create, Properties startParams)
| | public boolean | canSupport(Properties startParams)
| | public Boolean | doJoinOrderOptimization()
| | public QueryTreeNode | getCreateAliasNode(Object aliasName, Object targetName, Object aliasSpecificInfo, char aliasType, Boolean delimitedIdentifier, ContextManager cm)
Get one of the several types of create alias nodes. | | public QueryTreeNode | getNode(int nodeType, ContextManager cm)
| | public ResultSetNode | mapTableAsVTI(TableDescriptor td, String vtiClass, String correlationName, ResultColumnList resultColumns, Properties tableProperties, ContextManager cm)
Return a node that represents invocation of the virtual table
for the given table descriptor using the passed in vti class name.
Currently only handles no argument vtis corresponding to a subset
of the diagnostic tables. | | protected String | nodeName(int nodeType)

| getCreateAliasNode | | public QueryTreeNode getCreateAliasNode(Object aliasName, Object targetName, Object aliasSpecificInfo, char aliasType, Boolean delimitedIdentifier, ContextManager cm) throws StandardException(Code) | | Get one of the several types of create alias nodes. Carved out of parser
so this could be used by ALTER PUBLICATION.
Parameters:
aliasName - The name of the alias
Parameters:
targetName - The full path/method name
Parameters:
aliasSpecificInfo - The full path of the target method name,if any
Parameters:
aliasType - The type of alias to create
Parameters:
delimitedIdentifier - Whether or not to treat the class nameas a delimited identifier if trying toresolve it as a class alias.
Parameters:
cm - A ContextManager A CreateAliasNode matching the given parameters
exception:
StandardException - Thrown on error |
| mapTableAsVTI | | public ResultSetNode mapTableAsVTI(TableDescriptor td, String vtiClass, String correlationName, ResultColumnList resultColumns, Properties tableProperties, ContextManager cm) throws StandardException(Code) | | Return a node that represents invocation of the virtual table
for the given table descriptor using the passed in vti class name.
Currently only handles no argument vtis corresponding to a subset
of the diagnostic tables. (e.g. lock_table).
The node returned is a FROM_VTI node with a passed in NEW_INVOCATION_NODE
representing the class, with no arguments.
Other attributes of the original FROM_TABLE node (such as resultColumns)
are passed into the FROM_VTI node.

Parameters:
nodeType - A node type identifier from C_NodeTypes
exception:
