Interface BlockIterator.BlockIteratorProcedure

All Known Implementing Classes:

HorizontalLinePositionSearch, RayBlockHitTest

Enclosing class:

BlockIterator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface BlockIterator.BlockIteratorProcedure

This functional interface accepts the currently iterating block and also the entry / exit point of the ray. "t" is the value to multiply the direction with to get the exit point. The method returns false if you want to abort iteration early.

boolean	accept(int x, int y, int z, double px, double py, double pz, double qx, double qy, double qz)	Called by the iteration process to deliver the next block on the ray.

Method Details

accept

boolean accept(int x,
 int y,
 int z,
 double px,
 double py,
 double pz,
 double qx,
 double qy,
 double qz)

Called by the iteration process to deliver the next block on the ray. Returns FALSE if you with to end iteration before the iteration reaches maximum distance.

Parameters:

x - X-coordinate of the block

y - Y-coordinate of the block

z - Z-coordinate of the block

px - Relative X-coordinate of entry-point (0 - 1)

py - Relative Y-coordinate of entry-point (0 - 1)

pz - Relative Z-coordinate of entry-point (0 - 1)

qx - Relative X-coordinate of exit-point (0 - 1)

qy - Relative Y-coordinate of exit-point (0 - 1)

qz - Relative Z-coordinate of exit-point (0 - 1)

Returns:

TRUE if iteration should continue
