Class ColumnMetadata

java.lang.Object

org.modeshape.connector.meta.jdbc.ColumnMetadata

@Immutable
public class ColumnMetadata
extends Object

Container for column-level metadata. The fields in this class roughly parallel the information returned from the DatabaseMetaData.getColumns(String, String, String, String) method.

Method Detail

getName

public String getName()

Returns:

the column name (COLUMN_NAME in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getJdbcDataType

public int getJdbcDataType()

Returns:

the JDBC data type (from Types) (DATA_TYPE in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getTypeName

public String getTypeName()

Returns:

the database-dependent type name (TYPENAME in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getColumnSize

public int getColumnSize()

Returns:

the column size (length for character data types, precision for numeric data types) (COLUMN_SIZE in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getDecimalDigits

public int getDecimalDigits()

Returns:

the number of fractional digits in the column (DECIMAL_DIGITS in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getRadix

public int getRadix()

Returns:

the radix for the column (NUM_PREC_RADIX in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getNullable

public Boolean getNullable()

Returns:

whether the column allows NULLs or not (NULLABLE in the DatabaseMetaData.getColumns(String, String, String, String) result set); null indicates that it cannot be determined if the column allows NULLs.

getDescription

public String getDescription()

Returns:

the column description (REMARKS in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getDefaultValue

public String getDefaultValue()

Returns:

the default value for the column, if any (COLUMN_DEF in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getLength

public int getLength()

Returns:

the number of bytes in the column (for char types) (CHAR_OCTECT_LENGTH in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getOrdinalPosition

public int getOrdinalPosition()

Returns:

the 1-based index of the column within its table (ORDINAL_POSITION in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getScopeCatalogName

public String getScopeCatalogName()

Returns:

for columns of type REF, the catalog name of the target table (SCOPE_CATALOG in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getScopeSchemaName

public String getScopeSchemaName()

Returns:

for columns of type REF, the schema name of the target table (SCOPE_SCHEMA in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getScopeTableName

public String getScopeTableName()

Returns:

for columns of type REF, the name of the target table (SCOPE_TABLE in the DatabaseMetaData.getColumns(String, String, String, String) result set).

getSourceJdbcDataType

public Integer getSourceJdbcDataType()

Returns:

the source type of the referred type (from Types) for REF columns (SOURCE_DATA_TYPE in the DatabaseMetaData.getColumns(String, String, String, String) result set).
