Class ReadWriteMap<R,W>

java.lang.Object

org.epics.pvmanager.expression.DesiredRateReadWriteExpressionListImpl<R,W>

org.epics.pvmanager.expression.DesiredRateReadWriteExpressionImpl<Map<String,R>,Map<String,W>>

org.epics.pvmanager.expression.ReadWriteMap<R,W>

Type Parameters:

R - the type for the values in the read map

W - the type for the values in the write map

All Implemented Interfaces:

DesiredRateExpression<Map<String,R>>, DesiredRateExpressionList<Map<String,R>>, DesiredRateReadWriteExpression<Map<String,R>,Map<String,W>>, DesiredRateReadWriteExpressionList<Map<String,R>,Map<String,W>>, WriteExpression<Map<String,W>>, WriteExpressionList<Map<String,W>>

public class ReadWriteMap<R,W>
extends DesiredRateReadWriteExpressionImpl<Map<String,R>,Map<String,W>>

A read/write expression for a key/value map.

This expression is a combination of a ReadMap and a WriteMap. The map is dynamic: the child expressions can be added and removed while the reader is active.

There is currently no way to retrieve the individual errors for each element of the map. If the value is a VType, the connection can be retrieved by looking at the alarm.
