Version:

16.07.12, 2.10 revised (fk) Memory efficiency: Moved names/bits to attribute class to save 1 pointer when names/bits are unused (such as tex coords, vector field, other big arrays...).
05.10.05, 2.00 revised (kp) Handling of bits changed from arbitrary length array to single int.
03.07.04, 1.20 revised (kp) New methods to handle detail text.
18.04.03, 1.15 revised (kp) Unused instance variable m_constraint removed.
21.06.00, 1.10 revised (kp) Optional array with constraint indices added.
00.00.97, 1.00 created (kp)

Constructor Detail

P_Vector

public P_Vector()

Method Detail

clone

public java.lang.Object clone()

Clone object and all instance variables.

Overrides:

clone in class java.lang.Object

toString

public java.lang.String toString()

Create a multi-line string representation with detailed information about all instance variables.

Overrides:

toString in class java.lang.Object

getDetail

public java.lang.String getDetail()

Get longer detail text of vector.

Returns:

Detail text of vector

Since:

JavaView 3.29.004

Version:

03.07.04, 1.00 created (kp)

setDetail

public void setDetail(java.lang.String detail)

Set longer detail text of vector, e.g. to be shown as overlay text. Assigning null will remove the corresponding text label.

Parameters:

detail - New detail text of vector

Since:

JavaView 3.29.004

Version:

03.07.04, 1.00 created (kp)

getName

public java.lang.String getName()

Get name of vector.

Returns:

Name of vector

setName

public void setName(java.lang.String name)

Set name of vector, e.g. to be shown in display. Assigning null will remove the corresponding text label.

Parameters:

name - New name of vector

getURL

public java.lang.String getURL()

Get URL of vector.

Returns:

URL of vector

setURL

public void setURL(java.lang.String url)

Set name of vector, e.g. to be shown in display. Assigning null will remove the corresponding text label.

Parameters:

url - New URL of vector

getBits

public long getBits()

Get integer array with bits.

setTag

public void setTag(int aBit)

Sets a single bit. If the bit array does not exist then it is created. If the array too small then it is enlarged.

Parameters:

aBit - the index of the bit to be set

clearTag

public void clearTag(int aBit)

Clears a single bit.

Parameters:

aBit - the index of the bit to be cleared

hasTag

public boolean hasTag(int aBit)

Gets the value of a single bit.

Parameters:

aBit - the index of the bit to be gotten

clone

public static P_Vector[][] clone(P_Vector[][] src)

Duplicate array and all entries by recursively cloning all instance variables except inspector panels and lists of registered listeners. The parent relationship is maintained only within this class but not to external classes. In general, all links of the clone to external objects are set to null.

See Also:

copy(P_Vector)

Version:

12.12.00, 1.10 revised (kp) Check for missing entries.
05.07.00, 1.00 created (kp)

clone

public static P_Vector[] clone(P_Vector[] src)

Duplicate array and all entries by recursively cloning all instance variables except inspector panels and lists of registered listeners. The parent relationship is maintained only within this class but not to external classes. In general, all links of the clone to external objects are set to null.

See Also:

copy(P_Vector)

Version:

12.12.00, 1.10 revised (kp) Check for missing entries.
05.07.00, 1.00 created (kp)

copy

public void copy(P_Vector vec)

Copies the attribute set of another vector.

Parameters:

vec - the vector to be copied

invert

public static void invert(java.lang.Object[] arr,
                          int usedSize)

Invert the order of the first 'usedSize' entries inside the arr, i.e. the first entry becomes the 'usedSize-1' entry.

Parameters:

arr - array of objects.

usedSize - number of used entries
