Method Details

append

void append(double[] value)

Places a new value at the end of the existing value, increasing the field length accordingly.

Parameters:

value - The value to append value[0] = X
value[1] = Y
value[2] = Z

Throws:

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the vector definition.

clear

void clear()

Removes all values in the field and changes the field size to zero.

getValue

void getValue(double[][] vec)

Write the value of the event out to the given array.

Parameters:

vec - The array to be filled in where
vec[i][0] = X
vec[i][1] = Y
vec[i][2] = Z

Throws:

ArrayIndexOutOfBoundsException - The provided array was too small

getValue

void getValue(double[] vec)

Get the values of the event out flattened into a single 1D array. The array must be at least 3 times the size of the array.

Parameters:

vec - The array to be filled in where the vec[i + 0] = X
vec[i + 1] = Y
vec[i + 2] = Z

Throws:

ArrayIndexOutOfBoundsException - The provided array was too small

get1Value

void get1Value(int index,
 double[] vec)

Get the value of a particular vector value in the event out array.

Parameters:

index - The position to get the vector value from.

vec - The array to place the value in where. vec[0] = X
vec[1] = Y
vec[2] = Z

Throws:

ArrayIndexOutOfBoundsException - The provided array was too small or the index was outside the current data array bounds.

insertValue

void insertValue(int index,
 double[] value)
          throws ArrayIndexOutOfBoundsException

Inserts a value into an existing index of the field. Current field values from the index to the end of the field are shifted down and the field length is increased by one to accommodate the new element. If the index is out of the bounds of the current field an ArrayIndexOutofBoundsException will be generated.

Parameters:

index - The position at which to insert

value - The new element to insert value[0] = X
value[1] = Y
value[2] = Z

Throws:

ArrayIndexOutOfBoundsException - The index was outside the current field size.

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the vector definition.

removeValue

void removeValue(int index)
          throws ArrayIndexOutOfBoundsException

Removes one value from the field. Values at indices above the removed element will be shifted down by one and the size of the field will be reduced by one.

Parameters:

index - The position of the value to remove.

Throws:

ArrayIndexOutOfBoundsException - The index was outside the current field size.

setValue

void setValue(int numVec,
 double[] value)

Set the value of the array of 3D vectors. Input is an array of doubles If value[i] does not contain at least three values it will generate an ArrayIndexOutOfBoundsException. If value[i] contains more than three items only the first three values will be used and the rest ignored.

If one or more of the values for value[i] are null then the resulting event that is sent to the VRML scene graph is implementation dependent but no error indicator will be set here.

Parameters:

numVec - The number of items to copy from the array

value - The array of vec3d values where
value[i] = X
value[i+1] = Y
value[i+2] = Z

Throws:

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the vector definition.

setValue

void setValue(int numVec,
 double[][] value)

Set the value of the array of 3D vectors. Input is an array of doubles If value[i] does not contain at least three values it will generate an ArrayIndexOutOfBoundsException. If value[i] contains more than three items only the first three values will be used and the rest ignored.

If one or more of the values for value[i] are null then the resulting event that is sent to the VRML scene graph is implementation dependent but no error indicator will be set here.

Parameters:

numVec - The number of items to copy from the array

value - The array of vec3d values where
value[i][0] = X
value[i][1] = Y
value[i][2] = Z

Throws:

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the vector definition.

set1Value

void set1Value(int index,
 double[] value)

Set a particular vector value in the given eventIn array. To the VRML world this will generate a full MFVec3f event with the nominated index value changed.

The value array must contain at least three elements. If the array contains more than 3 values only the first 3 values will be used and the rest ignored.

If the index is out of the bounds of the current array of data values or the array of values does not contain at least 3 elements an ArrayIndexOutOfBoundsException will be generated.

Parameters:

index - The position to set the vector value

value - The array of vector values where
value[0] = X
value[1] = Y
value[2] = Z

Throws:

ArrayIndexOutOfBoundsException - A value did not contain at least 3 values for the vector
