Method Detail

add

protected void add(DeviceFilter filter)

addConfiguredRequirement

public void addConfiguredRequirement(Variable req)

addRequirement

public void addRequirement(Requirement requirement)

addConfiguredAnd

public void addConfiguredAnd(AndRelation andRelation)

addConfiguredOr

public void addConfiguredOr(OrRelation orRelation)

addConfiguredNot

public void addConfiguredNot(NotRelation notRelation)

addConfiguredNand

getFilters

public DeviceFilter[] getFilters()

getRequiredIdentifiers

public List<String> getRequiredIdentifiers()

Retrieves a list of the required device identifiers. This is a special case that allows a faster time for reading the device database, since only those devices need to be read that have the wanted identifier.

Returns:

a list of the required identifiers when only <identifier> requirements are used, otherwise null.
