setData

public void setData(double[] data,
                    double timeStep)

Sets the data points in this probe's numeric data.

The times for the data points can be evenly distributed, starting at 0 with a time step specified by timeStep, or their times can be explicitly set; for the latter case, timeStep must be set to NumericProbeBase.EXPLICIT_TIME.

Each data point is specified by a contiguous set of M values in data, where M is the probe data vector size as returned by NumericProbeBase.getVsize(). If the point times are explicitly specified, then these values must be preceeded by the point's time. The number of data points N is inferred from the length of data, which will be N*(1+M) if point times are explicity specified, and N*M otherwise.

Parameters:

data - contains the data values for all the points.

timeStep - time step in seconds, or NumericProbeBase.EXPLICIT_TIME if data contains the point times

addData

public void addData(double[] data,
                    double timeStep)

Adds one or more data points to this probe's numeric data.

The times for the data points can be evenly distributed, starting at 0 with a time step specified by timeStep, or their times can be explicitly set; for the latter case, timeStep must be set to NumericProbeBase.EXPLICIT_TIME.

Each data point is specified by a contiguous set of M values in data, where M is the probe data vector size as returned by NumericProbeBase.getVsize(). If the point times are explicitly specified, then these values must be preceeded by the point's time. The number of data points N is inferred from the length of data, which will be N*(1+M) if point times are explicity specified, and N*M otherwise.

Parameters:

data - contains the data values for all the points.

timeStep - time step in seconds, or NumericProbeBase.EXPLICIT_TIME if data contains the point times

hasState

public boolean hasState()

Description copied from interface: ModelComponent

Queries if this component has state. Structure change events involving components that have state will cause the current state history of of the system to be cleared.

Specified by:

hasState in interface ModelComponent

Overrides:

hasState in class Probe

Returns:

true if this component has state

createState

public ComponentState createState(ComponentState prevState)

Description copied from interface: HasState

Factory routine to create a state object for this component, which can then be used as an argument for HasState.setState(artisynth.core.modelbase.ComponentState) and HasState.getState(artisynth.core.modelbase.ComponentState). The state object does not have to be set to the component's current state. If the component does not have any state information, this method should return an instance of EmptyState.

Specified by:

createState in interface HasState

Overrides:

createState in class Probe

Parameters:

Get the current state of this component.

Specified by:

public void scan(ReaderTokenizer rtok,
                 java.lang.Object ref)
          throws java.io.IOException

Description copied from class: ModelComponentBase

Scans this element from a ReaderTokenizer. The expected text format is assumed to be compatible with that produced by write.

Specified by:

scan in interface ModelComponent

Specified by:

scan in interface Scannable

Overrides:

scan in class Probe

Parameters:

rtok - Tokenizer from which to scan the element

ref - optional reference object which can be used for resolving references to other objects

postscan

public void postscan(java.util.Deque<ScanToken> tokens,
                     CompositeComponent ancestor)
              throws java.io.IOException

Description copied from interface: PostScannable

Performs any required post-scanning for this component. This involves handling any information whose processing was deferred during the scan() method and stored in the token queue. The most common use of this method is to resolve the paths of component references, which may not have been created at the time of the initial scan() call.

Specified by:

postscan in interface PostScannable

Overrides:

postscan in class ModelComponentBase

Parameters:

tokens - token information that was stored during scan().

ancestor - ancestor component with respect to which reference component paths are defined.

Throws:

java.io.IOException - if an error is encountered (such as a reference to a non-existent component)

writeItems

public void writeItems(java.io.PrintWriter pw,
                       NumberFormat fmt,
                       CompositeComponent ancestor)
                throws java.io.IOException

Description copied from class: Probe

ancestor - ancestor component which respect to which references are expressed

Throws:

java.io.IOException - if an I/O error occurred

Overrides:

isInput in class Probe

Returns:

true if this is an input probe

set

public void set(Property[] props,
                java.lang.String[] driverExpressions,
                java.lang.String[] variableNames,
                int[] variableDimensions)

                java.lang.String[] variableNames,
                int[] variableDimensions,
                PlotTraceInfo[] traceInfos)

createNumericList

public void createNumericList(int vsize)

Overrides:

createNumericList in class NumericProbeBase

isDuplicatable

public boolean isDuplicatable()

Returns true if this component can be duplicated. Duplication means that we can expect to be able to make a complete copy of the component along with all it's external references. This method should return true if and only if CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) returns true.

This method is not currently used. It is intended to provide a faster way of determining if a component can be duplicated, without having to use CopyableComponent.getCopyReferences(java.util.List<artisynth.core.modelbase.ModelComponent>, artisynth.core.modelbase.ModelComponent) to build the list of copy references.

Specified by:

isDuplicatable in interface CopyableComponent

Returns:

true if this component can be duplicated.

getCopyReferences

public boolean getCopyReferences(java.util.List<ModelComponent> refs,
                                 ModelComponent ancestor)

Collects external references which must also be copied in order to duplicate this component. These references should exclude those which are contained within a specified component hierarchy. This method should return true if and only if CopyableComponent.isDuplicatable() returns true.

Specified by:

getCopyReferences in interface CopyableComponent

Parameters:

refs - list to which references are appended

ancestor - root node of the hierarchy from which references are to be excluded

Returns:

false if it is discovered that the component cannot be duplicated

copy

public ModelComponent copy(int flags,
                           java.util.Map<ModelComponent,ModelComponent> copyMap)

Description copied from interface: CopyableComponent

Create a copy of this component. If COPY_REFERENCES is set in flags, then any component referenced by this component should itself be set to a copy. This should be done first checking copyMap for an existing copy of the referenced component. If there is no existing copy, then a copy should be created by calling copy recursively and adding the new copy to copyMap.

Specified by:

copy in interface CopyableComponent

Overrides:

copy in class ModelComponentBase

Parameters:

flags - flags to control the copying

copyMap - map to possible existing instances of referenced components

Returns:

copy of this component
