Constructor Detail

DepthSort

public DepthSort()

Method Detail

sort

protected boolean sort()

Precomputes the ordering, returns true if failed.

reset

public void reset()

Reset the iterator.

Specified by:

reset in interface BrepIterator

next

Returns id of the next object.

Specified by:

next in interface BrepIterator

Returns:

Brep.NULL if there is no next object available.

toArray

public int[] toArray(int[] pre)

Sets the given property.

Specified by:

set in interface Property

Overrides:

set in class DefaultProperty

Parameters:

key - Key string.

value - The new value.

See Also:

Property.commit()

get

public java.lang.Object get(java.lang.String key)
