Method Details

build

public RSColumn[] build(ExtendedTypeMap typeMap)
                 throws SQLException,
IllegalStateException

Returns the array of RSColumns describing the result row, with an ExtendedType resolved for each column.

Throws:

SQLException

IllegalStateException

mergeResultSetAndPresetColumns

protected RSColumn[] mergeResultSetAndPresetColumns(ExtendedTypeMap typeMap)
                                             throws SQLException

Returns:

array of columns for ResultSet with overriding ColumnDescriptors from 'columns' Note: column will be overlooked, if column name is empty

Throws:

SQLException

columns

public RSColumn.RowBuilder columns(RSColumn... columns)

Sets an explicit set of columns. The builder may replace these with new instances to enforce the column capitalization policy and column Java type overrides.

resultSet

public RSColumn.RowBuilder resultSet(ResultSet resultSet)
                              throws SQLException

Throws:

SQLException

useLowercaseColumnNames

public RSColumn.RowBuilder useLowercaseColumnNames()

useUppercaseColumnNames

public RSColumn.RowBuilder useUppercaseColumnNames()

overrideColumnType

public RSColumn.RowBuilder overrideColumnType(String columnName,
 String type)

Registers a Java type override for the named column. The first override registered for a given column wins: subsequent calls for the same column are ignored, so callers can register higher-priority overrides first and follow with fallback defaults without having to check what is already registered.

validateDuplicateColumnNames

public RSColumn.RowBuilder validateDuplicateColumnNames()

mergeColumnsWithRsMetadata

public RSColumn.RowBuilder mergeColumnsWithRsMetadata()

dbEntity

public RSColumn.RowBuilder dbEntity(DbEntity dbEntity)

Sets the root DbEntity used to resolve each column's DbAttribute by name. Optional - when not set, column attributes are left as provided.
