Method Summary

Modifier and Type	Method	Description
AbstractPaging	extractDialect(K dialectKey, org.apache.ibatis.mapping.MappedStatement ms, DataSource dataSource, Properties properties)	Extracts and returns the appropriate AbstractPaging dialect.
K	extractDialectKey(org.apache.ibatis.mapping.MappedStatement ms, DataSource dataSource, Properties properties)	Retrieves the key used for caching the return value of the extractDialect(K, org.apache.ibatis.mapping.MappedStatement, javax.sql.DataSource, java.util.Properties) method.

Method Details

extractDialectKey

K extractDialectKey(org.apache.ibatis.mapping.MappedStatement ms,
 DataSource dataSource,
 Properties properties)

Retrieves the key used for caching the return value of the extractDialect(K, org.apache.ibatis.mapping.MappedStatement, javax.sql.DataSource, java.util.Properties) method. If this method returns null, the dialect will not be cached. If a key is returned, the system first checks if it already exists. If not, extractDialect(K, org.apache.ibatis.mapping.MappedStatement, javax.sql.DataSource, java.util.Properties) is called, and the result is then cached.

Parameters:

ms - the MappedStatement being executed

dataSource - the DataSource associated with the MappedStatement

properties - the configuration properties

Returns:

the cache key for the dialect, or null if caching is not desired

extractDialect

AbstractPaging extractDialect(K dialectKey,
 org.apache.ibatis.mapping.MappedStatement ms,
 DataSource dataSource,
 Properties properties)

Extracts and returns the appropriate AbstractPaging dialect. This method is responsible for creating or retrieving the dialect instance based on the provided information.

Parameters:

dialectKey - the cache key for the dialect, as returned by extractDialectKey(org.apache.ibatis.mapping.MappedStatement, javax.sql.DataSource, java.util.Properties)

ms - the MappedStatement being executed

dataSource - the DataSource associated with the MappedStatement

properties - the configuration properties

Returns:

an instance of AbstractPaging representing the determined dialect
