isCompatibleWith
public boolean isCompatibleWith(RDBMSColumnInfo colInfo)
Description copied from class:SQLTypeInfo
Convenience method for returning if this type is compatible with the provided column. Compares the data type of each record, and returns true if the types are equivalent. For example one could be VARCHAR, and the other LONGVARCHAR so they both store string data, and hence they are compatible.- Overrides:
isCompatibleWith
in classSQLTypeInfo
- Parameters:
colInfo
- The column- Returns:
- Whether they are considered compatible
