AbstractCursor.NumberAccessor (Apache Calcite Avatica 1.15.0 API)

java.lang.Object
- org.apache.calcite.avatica.util.AbstractCursor.AccessorImpl
- - org.apache.calcite.avatica.util.AbstractCursor.BigNumberAccessor
  - - org.apache.calcite.avatica.util.AbstractCursor.NumberAccessor

All Implemented Interfaces:

Cursor.Accessor

Direct Known Subclasses:

AbstractCursor.DateFromNumberAccessor, AbstractCursor.TimeFromNumberAccessor, AbstractCursor.TimestampFromNumberAccessor

Enclosing class:

AbstractCursor
```
static class AbstractCursor.NumberAccessor
extends AbstractCursor.BigNumberAccessor
```
Accessor that assumes that the underlying value is a Number; corresponds to Types.NUMERIC.
This is useful when numbers have been translated over JSON. JSON converts a 0L (0 long) value to the string "0" and back to 0 (0 int). So you cannot be sure that the source and target type are the same.
