Method Detail

getSharedPool

public static TParserPool getSharedPool()

Gets the shared global parser pool instance. Creates it lazily with double-checked locking.

Returns:

Shared parser pool instance

getNamedPool

public static TParserPool getNamedPool(String name,
                                       int poolSize)

Creates or gets a named parser pool. Useful for isolating pools for different components or use cases.

Parameters:

name - Pool name

poolSize - Size of the pool

Returns:

Named parser pool instance

getNamedPool

public static TParserPool getNamedPool(String name)

Gets a named parser pool with default size.

Parameters:

name - Pool name

Returns:

Named parser pool instance

setDefaultPoolSize

public static void setDefaultPoolSize(int size)

Sets the default pool size for new pools.

Parameters:

size - Default pool size

resetSharedPool

public static void resetSharedPool()

Resets the shared pool instance. The old pool is shut down and a new one will be created on next access.

removeNamedPool

public static void removeNamedPool(String name)

Removes and shuts down a named pool.

Parameters:

name - Pool name

shutdownAll

public static void shutdownAll()

Shuts down all pools.

parseSQL

public static int parseSQL(EDbVendor vendor,
                           String sqlText)

Convenience method to parse SQL using the shared pool. This is a drop-in replacement for direct TGSqlParser usage.

Parameters:

vendor - Database vendor

sqlText - SQL text to parse

Returns:

Parse result (0 for success, non-zero for errors)

tokenizeSQL

public static int tokenizeSQL(EDbVendor vendor,
                              String sqlText)

Convenience method to tokenize SQL using the shared pool.

Parameters:

vendor - Database vendor

sqlText - SQL text to tokenize

Returns:

0 for success, -1 for error

getAllStatistics

public static String getAllStatistics()

Gets statistics for all pools.

Returns:

String representation of all pool statistics
