public class BaseColumn

extends Object

implements ColumnModel, Serializable

An implementation of ColumnModel. Extend it and set each of its properties.

Calls to MetaDataModel.getJavaColumnType call getMetaColumnType() below.

ResultSetMetaData methods are mirrored here, see their documentation for descriptions. Some drivers do not support all ResultSetMetaData methods. If they do not the following defaults are used:

NAME	VALUE
catalog	null
displayWidth	25
name	null
label	null
type	java.sql.Types.OTHER
typeName	"OTHER"
precision	5
scale	5
schema	null
table	null
isAutoIncrement	false
isCaseSensitive	false
isCurrency	false
isDefinitelyWritable	true
isNullable	ResultSetMetaData.columnNullable
isReadOnly	false
isSearchable	true
isSigned	false
isWritable	true

Method Detail

getMetaColumnType

public int getMetaColumnType()

Return one of MetaDataModel types. Java object types and java.sql.Types types are mapped to MetaDataModel types.

Specified by:

getMetaColumnType in interface ColumnModel

Returns:

this column's type as one of the MetaDataModel type constants.
