Method Details

indexOf

public int indexOf(int offset,
 CircularArray_F32.Match condition)

Searches for the next element starting at index "offset" that the passed in condition is true for. Returns -1 if no match was found

popHead

public float popHead()

Returns and removes the first element from the queue.

Returns:

first element in the queue

popTail

public float popTail()

Returns and removes the last element from the queue.

Returns:

last element in the queue

head

public float head()

Value of the first element in the queue

tail

public float tail()

Value of the last element in the queue

get

public float get(int index)

Returns the element in the queue at index. No bounds check is performed and a garbage value might be returned.

Parameters:

index - Which element in the queue you wish to access

Returns:

the element's value

set

public void set(int index,
 float value)

add

public void add(float value)

Adds a new element to the queue, but if the queue is full write over the oldest element.

Parameters:

value - Value which is to be added

setTo

public CircularArray_F32 setTo(CircularArray_F32 original)

copy

public CircularArray_F32 copy()

resizeQueue

public void resizeQueue(int maxSize)

Changes the size of the inner array. Does not save old values.

shiftElements

protected void shiftElements(int src0,
 int dst0,
 int length)

Description copied from class: CircularArrayBase

Copies the value in the src into dst inside the inner array. Needs to handle wrap around

Specified by:

shiftElements in class CircularArrayBase

getMaxSize

public int getMaxSize()

Description copied from class: CircularArrayBase

Number of elements in the inner array

Specified by:

getMaxSize in class CircularArrayBase

innerArray

public <T> T innerArray()

Description copied from class: CircularArrayBase

Reference to the inner array

Specified by:
