Constructor Detail

DesiredRateReadWriteExpressionImpl

public DesiredRateReadWriteExpressionImpl(DesiredRateExpression<R> desiredRateExpression,
                                  WriteExpression<W> writeExpression)

Creates an expression that can be both read at the desired rate and written.

Parameters:

desiredRateExpression - the read part of the expression

writeExpression - the write part of the expression

Method Detail

as

public final DesiredRateReadWriteExpressionImpl<R,W> as(String name)

Description copied from interface: DesiredRateExpression

Changes the name for this expression

Specified by:

as in interface DesiredRateExpression<R>

Specified by:

as in interface DesiredRateReadWriteExpression<R,W>

Parameters:

name - new name

Returns:

this

getName

public final String getName()

Description copied from interface: DesiredRateExpression

Name of this expression.

Specified by:

getName in interface DesiredRateExpression<R>

Specified by:

getName in interface WriteExpression<W>

Returns:

the expression name

getFunction

public final ReadFunction<R> getFunction()

Description copied from interface: DesiredRateExpression

The function that calculates this expression.

Specified by:

getFunction in interface DesiredRateExpression<R>

Returns:

the expression function

getDesiredRateExpressionImpl

the expression function

fillWriteRecipe

public void fillWriteRecipe(PVWriterDirector director,
                   WriteRecipeBuilder builder)

Description copied from interface: WriteExpression

Prepares the recipe to connect the channels needed by this expression.

A dynamic expression, one for which the child expressions can change, can keep a reference to the director to connect/disconnect new child expressions.

Specified by:

fillWriteRecipe in interface WriteExpression<W>

Parameters:

director - the director for the reader

builder - the recipe to fill
