static class	SelectableConsumer.MutableSelectableMapping

Method Summary

Modifier and Type	Method	Description
void	accept(int selectionIndex, SelectableMapping selectableMapping)	Accept the selectable mapping.
default void	accept(String tableName, String[] columnNames, IntFunction<JdbcMapping> jdbcMappings)	Simple form allowing visitation over a number of column names within a table.
default void	accept(String tableName, JdbcMappingContainer base, String[] columnNames)	Simple form of visitation over a number of columns by name, using a separate SelectableMappings as a base for additional details.

Method Details

accept

void accept(int selectionIndex,
 SelectableMapping selectableMapping)

Accept the selectable mapping. `selectIndex` is its position, the meaning of which depends on the impl and whether SelectableMappings.forEachSelectable(SelectableConsumer) or SelectableMappings.forEachSelectable(int, SelectableConsumer) was used

accept

default void accept(String tableName,
 JdbcMappingContainer base,
 String[] columnNames)

Simple form of visitation over a number of columns by name, using a separate SelectableMappings as a base for additional details.

Intended for use in visiting table keys, where we know JdbcMappings, etc. from the identifier.

The expectation here is for the following details to be available:

• SelectableMapping.getContainingTableExpression()
• SelectableMapping.getSelectionExpression() (the column name)
• SelectableMapping.getWriteExpression()
• SqlTypedMapping.getJdbcMapping()

accept

default void accept(String tableName,
 String[] columnNames,
 IntFunction<JdbcMapping> jdbcMappings)

Simple form allowing visitation over a number of column names within a table. Very limited functionality in terms of the visited SelectableMappings will not have any defined JdbcMapping, etc
