方法详细资料

calculatePositions

public java.util.Map<java.lang.String,CmsPositionBean> calculatePositions()

Calculates non-overlapping positions for the button bars and returns them in a map with the element ids as keys.

返回:

the map of non-overlapping positions

checkCollision

protected boolean checkCollision()

Checks whether a collision occurs and handle it if necessary.

返回:

true if a collision occured

handleCollision

protected void handleCollision(CmsPositionBean p1,
                   CmsPositionBean p2)

Handles a collision by moving the lower position down.

参数:

p1 - the first position

p2 - the second position

intersectIntervals

protected boolean intersectIntervals(int a1,
                         int a2,
                         int b1,
                         int b2)

Checks for intersection of two one-dimensional intervals.

参数:

a1 - the left edge of the first interval

a2 - the right edge of the first interval

b1 - the left edge of the second interval

b2 - the right edge of the second interval

返回:

true if the intervals intersect

intersectsHorizontally

protected boolean intersectsHorizontally(CmsPositionBean p1,
                             CmsPositionBean p2)

Checks whether two positions intersect horizontally.

参数:

p1 - the first position

p2 - the second position

返回:

true if the positions intersect horizontally

intersectsVertically

protected boolean intersectsVertically(CmsPositionBean p1,
                           CmsPositionBean p2)

Checks whether two positions intersect vertically.

参数:

p1 - the first position

p2 - the second position

返回:

if the positions intersect vertically

sortByLeft

protected void sortByLeft()

Sorts the internal list of positions by their left edge.
