Method Details

append

void append(float[] 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] = Red component [0-1]
value[1] = Green component [0-1]
value[2] = Blue component [0-1]
value[3] = Alpha component [0-1]

Throws:

ArrayIndexOutOfBoundsException - The provided array was too small

clear

void clear()

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

getValue

void getValue(float[][] col)

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

Parameters:

col - The array to be filled in where
col[i][0] = Red component [0-1]
col[i][1] = Green component [0-1]
col[i][2] = Blue component [0-1]
col[i][3] = Alpha component [0-1]

Throws:

ArrayIndexOutOfBoundsException - The provided array was too small

getValue

void getValue(float[] col)

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:

col - The array to be filled in where the col[i + 0] = Red component [0-1]
col[i + 1] = Green component [0-1]
col[i + 2] = Blue component [0-1]
col[i + 3] = Alpha component [0-1]

Throws:

ArrayIndexOutOfBoundsException - The provided array was too small

get1Value

void get1Value(int index,
 float[] col)

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

Parameters:

index - The position to get the vectory value from.

col - The array to place the value in where. col[0] = Red component [0-1]
col[1] = Green component [0-1]
col[2] = Blue component [0-1]
col[3] = Alpha component [0-1]

Throws:

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

insertValue

void insertValue(int index,
 float[] 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] = Red component [0-1]
value[1] = Green component [0-1]
value[2] = Blue component [0-1]
value[3] = Alpha component [0-1]

Throws:

ArrayIndexOutOfBoundsException - The index was outside the current field size.

ArrayIndexOutOfBoundsException - The provided array was too small

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 numColors,
 float[] value)

Set the value of from the flat array of colours. Input is an array of colour values in RGBA order [n, n+1, n+2, n+3]. All colour values are required to be in the range 0-1. Colour values outside of this range will generate an IllegalArgumentException. If the array does not contain at least numColors * 4 values it will generate an ArrayIndexOutOfBoundsException.

Parameters:

numColors - The number of colour values in this array to copy

value - The array of colour values where
value[i] = Red component [0-1]
value[i+1] = Green component [0-1]
value[i+2] = Blue component [0-1]
value[i+3] = Blue component [0-1]

Throws:

IllegalArgumentException - A colour value(s) was out of range

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the colour component

setValue

void setValue(int numColors,
 float[][] value)

Set the value of the array of colours. Input is an array of colour values in RGBA order. All colour values are required to be in the range 0-1. Colour values outside of this range will generate an IllegalArgumentException. If value[i] that does not contain at least three values will generate an ArrayIndexOutOfBoundsException. If value[i] contains more than three items only the first three values will be used and the rest ignored.

Parameters:

numColors - The number of colour values in this array to copy

value - The array of colour values where
value[i][0] = Red component [0-1]
value[i][1] = Green component [0-1]
value[i][2] = Blue component [0-1]
value[i][3] = Alpha component [0-1]

Throws:

IllegalArgumentException - A colour value(s) was out of range

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the colour component

set1Value

void set1Value(int index,
 float[] value)

Set a particular colour value in the given eventIn array. To the VRML world this will generate a full MFColor event with the nominated index value changed. Colour values are required to be in the range [0-1].

The value array must contain at least three elements. If the array contains more than 4 values only the first three 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. If the colour values are out of range an IllegalArgumentException will be generated.

Parameters:

index - The position to set the colour value

value - The array of colour values where
value[0] = Red component [0-1]
value[1] = Green component [0-1]
value[2] = Blue component [0-1]
value[3] = Alpha component [0-1]

Throws:

IllegalArgumentException - A colour value(s) was out of range

ArrayIndexOutOfBoundsException - A value did not contain at least three values for the colour component
