public class ExpressionBlock
extends AbstractDigitalExpression
implements PropertyChangeListener

This expression evaluates the state of a Block. The supported characteristics are:

• Is [not] Occupied (based on occupancy sensor state)
• Is [not] Unoccupied (based on occupancy sensor state)
• Is [not] Other (UNKNOWN, INCONSISTENT, UNDETECTED)
• Is [not] Allocated (based on the LayoutBlock useAlternateColor)
• Value [not] equals string

Method Details

getDeepCopy

public Base getDeepCopy(Map<String,String> systemNames,
 Map<String,String> userNames)
                 throws ParserException

Description copied from interface: Base

Create a deep copy of myself and my children The item needs to try to lookup itself in both systemNames and userNames to see if the user has given a new system name and/or a new user name.If no new system name is given, an auto system name is used. If no user name is given, a null user name is used.

Specified by:

getDeepCopy in interface Base

Parameters:

systemNames - a map of old and new system name

userNames - a map of old system name and new user name

Returns:

a deep copy

Throws:

ParserException

getSelectNamedBean

public Is_IsNot_Enum get_Is_IsNot()

getCategory

public LogixNG_Category getCategory()

Get the category.

Specified by:

getCategory in interface Base

Overrides:

getCategory in class AbstractBase

Returns:

the category

isBlockAllocated

public boolean isBlockAllocated(Block block)

A block is considered to be allocated if the related layout block has use extra color enabled.

Parameters:

block - The block whose allocation state is requested.

Returns:

true if the layout block is using the extra color.

evaluate

public boolean evaluate()
                 throws JmriException

Evaluate this expression.

Specified by:

evaluate in interface DigitalExpression

Returns:

the result of the evaluation

Throws:

JmriException - when an exception occurs

Description copied from class: AbstractBase

Get a child of this item

Specified by:

getChild in interface Base

Overrides:

getChild in class AbstractBase

Parameters:

index - the index of the child to get

Returns:

the child

Throws:

IllegalArgumentException - if the index is less than 0 or greater or equal with the value returned by getChildCount()

UnsupportedOperationException - when needed

getChildCount

public int getChildCount()

Description copied from class: AbstractBase
