All known Subclasses: org.apache.derby.impl.tools.ij.utilMain14,
| utilMain | | public class utilMain implements java.security.PrivilegedAction(Code) | | This class is utilities specific to the two ij Main's.
This factoring enables sharing the functionality for
single and dual connection ij runs.

Set up the test to run with 'numConnections' connections/users. | | public | utilMain(int numConnections, LocalizedOutput out, Hashtable ignoreErrors)
Set up the test to run with 'numConnections' connections/users.
Parameters:

| Method Summary | |
| ijResult | absolute(ResultSet rs, int row)
Position on the specified row of the specified ResultSet. | | ijResult | afterLast(ResultSet rs)
Position after the last row of the specified ResultSet
and return NULL to the user. | | ijResult | beforeFirst(ResultSet rs)
Position before the first row of the specified ResultSet
and return NULL to the user. | | Statement | createStatement(Connection conn, int scrollType, int holdType)
Create the right kind of statement (scrolling or not)
off of the specified connection. | | static void | doPrompt(boolean newStatement, LocalizedOutput out, String tag)
REMIND: eventually this might be part of StatementFinder,
used at each carriage return to show that it is still "live"
when it is reading multi-line input. | | ijResult | first(ResultSet rs)

and return that row to the user. | | Properties | getConnAttributeDefaults()

Retrieves the current holdability of ResultSet objects created using this
Connection object. | | public void | go(LocalizedInput[] in, LocalizedOutput out, Properties connAttributeDefaults)
run ij over the specified input, sending output to the
specified output. | | public int | goScript(Connection conn, LocalizedInput in)
Support to run a script. | | public void | initFromEnvironment()
Initialize the connections from the environment. | | ijResult | last(ResultSet rs)

| | ijResult | previous(ResultSet rs)
Position on the previous row of the specified ResultSet
and return that row to the user. | | ijResult | relative(ResultSet rs, int row)
Move the cursor position by the specified amount. | | final public Object | run()

| utilMain | | utilMain(int numConnections, LocalizedOutput out) throws ijFatalException(Code) | | Set up the test to run with 'numConnections' connections/users.
Parameters:
numConnections - The number of connections/users to test. |
| utilMain | | public utilMain(int numConnections, LocalizedOutput out, Hashtable ignoreErrors) throws ijFatalException(Code) | | Set up the test to run with 'numConnections' connections/users.
Parameters:
numConnections - The number of connections/users to test.
Parameters:
ignoreErrors - A list of errors to ignore. If null,all errors are printed out and nothingis fatal. If non-null, if an error ishit and it is in this list, it is silently ignore. Otherwise, an ijFatalException isthrown. ignoreErrors is used for stresstests. |

| afterLast | | ijResult afterLast(ResultSet rs) throws SQLException(Code) | | Position after the last row of the specified ResultSet
and return NULL to the user.
Parameters:

| createStatement | | Statement createStatement(Connection conn, int scrollType, int holdType) throws SQLException(Code) | | Create the right kind of statement (scrolling or not)
off of the specified connection.
Parameters:
conn - The connection.
Parameters:
scrollType - The scroll type of the cursor. The statement. |
| doPrompt | | static void doPrompt(boolean newStatement, LocalizedOutput out, String tag)(Code) | | REMIND: eventually this might be part of StatementFinder,
used at each carriage return to show that it is still "live"
when it is reading multi-line input.
|
| first | | ijResult first(ResultSet rs) throws SQLException(Code) | | Position on the first row of the specified ResultSet
and return that row to the user.
Parameters:
rs - The specified ResultSet. The first row of the ResultSet.
exception:
SQLException - thrown on error.(first() not supported pre-JDBC2.0) |
| getCurrentRowNumber | | int getCurrentRowNumber(ResultSet rs) throws SQLException(Code) | | Get the current row number
Parameters:
rs - The specified ResultSet. The current row number
exception:
SQLException - thrown on error.(getRow() not supported pre-JDBC2.0) |
| getHoldability | | int getHoldability(Connection conn) throws SQLException(Code) | | Retrieves the current holdability of ResultSet objects created using this
Connection object. We implement this using reflection in jdk13 and lower
The holdability, one of ResultSet.HOLD_CURSORS_OVER_COMMITor ResultSet.CLOSE_CURSORS_AT_COMMIT |
| go | | public void go(LocalizedInput[] in, LocalizedOutput out, Properties connAttributeDefaults) throws ijFatalException(Code) | | run ij over the specified input, sending output to the
specified output. Any prior input and output will be lost.
