Scope (jOOQ 3.9.6 API)

All Known Subinterfaces:

BindContext, BindingGetResultSetContext, BindingGetSQLInputContext, BindingGetStatementContext, BindingRegisterContext, BindingSetSQLOutputContext, BindingSetStatementContext, BindingSQLContext, Context<C>, DSLContext, ExecuteContext, RecordContext, RenderContext, TransactionContext, VisitContext

All Known Implementing Classes:

DefaultDSLContext
```
public interface Scope
```
Scope implementations provide access to a variety of objects that are available from a given scope.
The scope of the various objects contained in this type (e.g. configuration(), settings(), etc.) are implementation dependent and will be specified by the concrete subtype of Scope. Examples of such scope types are:
- ExecuteContext: A scope that covers a single execution of a Query
- Context: A scope that covers a single traversal of a QueryPart expression tree to produce a SQL string and / or a list of bind variables.
- VisitContext: A scope that that covers a single traversal of a QueryPart expression tree (just like Context), in the presence of at least one VisitListener.
- RecordContext: A scope that covers a single record operation, such as UpdatableRecord.store().
- TransactionContext: A scope that covers the execution (or nesting) of a single transaction.
One of Scope's most interesting features for client code implementing any SPI is the data() map, which provides access to a Map where client code can register user-defined values for the entire lifetime of a scope. For instance, in an ExecuteListener implementation that measures time for fetching data, it is perfectly possible to store timestamps in that map:
```
 class FetchTimeMeasuringListener extends DefaultExecuteListener {
 @Override
 public void fetchStart(ExecuteContext ctx) {

 // Put any arbitrary object in this map:
 ctx.data("org.jooq.example.fetch-start-time", System.nanoTime());
 }

 @Override
 public void fetchEnd(ExecuteContext ctx) {

 // Retrieve that object again in a later step:
 Long startTime = (Long) ctx.data("org.jooq.example.fetch-start-time");
 System.out.println("Time taken: " + (System.nanoTime() - startTime) / 1000 / 1000.0 + " ms");
 }
 }
 
```

- Method Detail
 - configuration
```
Configuration configuration()
```
 The configuration of the current scope.
 - settings
```
Settings settings()
```
 The settings wrapped by this context.
 This method is a convenient way of accessing configuration().settings().
 - dialect
```
SQLDialect dialect()
```
 The SQLDialect wrapped by this context.
 This method is a convenient way of accessing configuration().dialect().
 - family
```
SQLDialect family()
```
 The SQLDialect.family() wrapped by this context.
 This method is a convenient way of accessing configuration().dialect().family().
 - data
```
Map<Object,Object> data()
```
 Get all custom data from this Scope.
 This is custom data that was previously set to the context using data(Object, Object). Use custom data if you want to pass data to QueryPart objects for a given Scope.
 
 Returns:
 
 The custom data. This is never null
 - data
```
Object data(Object key)
```
 Get some custom data from this Scope.
 This is custom data that was previously set to the context using data(Object, Object). Use custom data if you want to pass data to QueryPart objects for a given Scope
 
 Parameters:
 
 key - A key to identify the custom data
 
 Returns:
 
 The custom data or null if no such data is contained in this Scope
 - data
```
Object data(Object key,
 Object value)
```
 Set some custom data to this Scope.
 This is custom data that was previously set to the context using data(Object, Object). Use custom data if you want to pass data to QueryPart objects for a given Scope.
 
 Parameters:
 
 key - A key to identify the custom data
 
 value - The custom data
 
 Returns:
 
 The previously set custom data or null if no data was previously set for the given key
