All Implemented Interfaces:

java.lang.Cloneable, SGTData

public class SGTVector

extends java.lang.Object

implements SGTData, java.lang.Cloneable

Defines a data object to be a Vector. Interpretation of U and V is determined by the CoordinateSystem. For Cartesian, U and V are the Cartesian vector components. For Polar , U and V are R (radius) and Theta (angle) vector components, respectively.

Constructor Detail

SGTVector

public SGTVector()

Default constructor.

SGTVector

public SGTVector(SGTGrid uComp,
                 SGTGrid vComp)

Construct a SGTVector from two components. The two components must match in both SGTData and CoordinateSystem Interfaces. Both components must be the same shape.

Parameters:

uComp - U component of the vector

vComp - V component of the vector

Method Detail

copy

public SGTData copy()

Create a copy. Creates a shallow copy.

Specified by:

copy in interface SGTData

SGTData

getU

public SGTGrid getU()

Get the U component.

Returns:

U component

getV

public SGTGrid getV()

Get the V component.

Returns:

V component

setU

public void setU(SGTGrid uComp)

Set the U component.

Parameters:

uComp - U component

setV

public void setV(SGTGrid vComp)

Set the V component.

Parameters:

vComp - V component

setComponents

public void setComponents(SGTGrid uComp,
                          SGTGrid vComp)

Set the vector components.

Parameters:

uComp - U component

vComp - V component

setTitle

public void setTitle(java.lang.String title)

Set the vector's title.

Parameters:

title -

getKeyTitle

public SGLabel getKeyTitle()

Description copied from interface: SGTData

Get a title formatted for a Key. JPlotLayout will use this if an explicit Key title is not given in the addData method.

Specified by:

getKeyTitle in interface SGTData

Following copied from interface: gov.noaa.pmel.sgt.dm.SGTData

SGLabel, ColorKey, LineKey, PointCollectionKey, VectorKey

setKeyTitle

public void setKeyTitle(SGLabel title)

Set the title formatted for the VectorKey.

getId

public java.lang.String getId()

Get the unique identifier. The presence of the identifier is optional, but if it is present it should be unique. This field is used to search for the layer that contains the data.

Specified by:

getId in interface SGTData

Returns:

unique identifier

See Also:

Pane, Layer

setId

public void setId(java.lang.String ident)

Set the unique identifier.

getTitle

public java.lang.String getTitle()

Get the vector's title.

Specified by:

getTitle in interface SGTData

Returns:

the title

isXTime

public boolean isXTime()

Description copied from interface: SGTData

Returns true if the X coordinate is Time.

Specified by:

isXTime in interface SGTData

isYTime

public boolean isYTime()

Description copied from interface: SGTData

Returns true if the Y coordinate is Time.

Specified by:
