Method Detail

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class ModelAgentBase

Returns:

static information for all exported properties

getDefaultStartTime

public static double getDefaultStartTime()

getDefaultStopTime

public static double getDefaultStopTime()

getDefaultScale

public static double getDefaultScale()

getDefaultUpdateInterval

public static double getDefaultUpdateInterval()

getProperty

public Property getProperty(java.lang.String name)

Description copied from class: ModelComponentBase

Returns a property associated with a specified path name. All properties exported by this object must have a name which is a valid Java identifier. Specifying one of these names causes the corresponding Property to be returned. Handles to sub-properties can also be obtained by delimiting the sub-property name(s) by '.' characters. A sub-property exists if the value of a property is itself an object which exports properties. It is only possible to obtain a sub-property handle if each of its ancestor properties exports their values by reference.

Specified by:

getProperty in interface HasProperties

Overrides:

getProperty in class ModelComponentBase

Parameters:

name - name of the desired property or sub-property

Returns:

handle to the property

getStartTime

public void setStartStopTimes(double startTime,
                              double stopTime)

getScale

setScale

public void setScale(double s)

setScalable

public void setScalable(boolean enable)

isScalable

public boolean isScalable()

getUpdateInterval

public double getUpdateInterval()

setUpdateInterval

public void setUpdateInterval(double t)

setName

public void setName(java.lang.String name)

Sets the name of this component. When the name is set, this method should call notifyParentOfChange with a NameChangeEvent so that it's parent can update the name map entry and other ancestors can adjust for the new name.

Component names can be specified as null. However, if not null, they should have non-zero length and should not begin with a digit or contain the characters '.' or '/'. Implementations can use ModelComponentBase.checkName() to determine if a proposed name is valid.

Specified by:

setName in interface ModelComponent

Overrides:

setName in class ModelComponentBase

Parameters:

name - new component name

hasChildren

public boolean hasChildren()

Specified by:

Overrides:

Overrides:

getChildren in class ModelComponentBase

isEventTime

nextEventTime

public double nextEventTime(double t)

apply

public abstract void apply(double t)

Called when the probe is being applied to a model

scan

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 ModelComponentBase

Parameters:

rtok - Tokenizer from which to scan the element

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

Throws:

java.io.IOException - if an I/O or formatting error occured

isAttachedFileRelative

public boolean isAttachedFileRelative()

getAttachedFileName

public java.lang.String getAttachedFileName()

hasAttachedFile

public boolean hasAttachedFile()

setTrack

public void setTrack(int num)

Sets the Timeline track number associated with this probe. The Timeline should use this method to keep the track information current.

Parameters:

num - new track number

getTrack

public java.lang.Integer getTrack()

Returns the Timeline track number associated with this probe.

Returns:

timeline track number

isInput

public boolean isInput()

Returns true if this probe is an input probe, and false otherwise.

Returns:

true if this is an input probe

isSettable

public boolean isSettable()

setData

public void setData(double sec)

isPrintable

public boolean isPrintable()

print

public void print(double sec)

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 ModelComponentBase

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.

Parameters:

prevState - If non-null, supplies a previous state that was created by this component and which can be used to provide pre-sizing hints.

Returns:

new object for storing this component's state

getState

public void getState(ComponentState state)

Description copied from interface: HasState

Get the current state of this component.

Parameters:

state - receives the state information

setState

public void setState(ComponentState state)

Description copied from interface: HasState

Set the state of this component.

Parameters:

state - state to be copied

getInitialState

public void getInitialState(ComponentState newstate,
                            ComponentState oldstate)

Description copied from interface: HasState

Gets an initial state for this component and returns the value in state. If prevstate is non-null, then it is assumed to contain a previous initial state value returned by this method, and state should be set to be as consistent with this previous state as possible. For example, suppose that this component currently contains subcomponents A, B, and C, while the prevstate contains the state from a previous time when it had components B, C, and D. Then state should contain substate values for B and C that are taken from prevstate. To facilitate this, the information returned in state should contain additional information such as the identities of all the (current) sub-components.

Parameters:

newstate - receives the state information

oldstate - previous state information; may be null.
