JoinPoints()

void ON_MeshXPointPool::JoinPoints	(	ON_SimpleArray< ON_MeshXPoint * > *	starts,
		ON_SimpleArray< ON_MeshXPointPair > *	pairs,
		int(*)(const ON_MeshXPoint *, const ON_MeshXPoint *)	compare_points_func
	)

Description: Join the points into connected intersection components by setting the ON_MeshXPoint::m_p[] pointers to the previous and next points in the intersection component. The first point of an intersection component has zero m_p[0] and nonzero m_p[1] values. The last point of an intersection component has nonzero m_p[0] and zero m_p[1] values. Parameters: starts - [out] (pass null if you do not want this information) For each intersection component, the first point in the component is appended to starts[].
pairs - [out]
(pass null if you do not want this information) For each intersection component, a pair with the first and last points in intersection component is appended to pairs[]. compare_points_func - [in] If compare_points_func() is null, then the function ON_MeshXPoint::CompareLocationsAndId() is used to decide if points are coincident. If compare_points_func() is not null, it must be a function that can be used to quick sort an array of ON_MeshXPoint elements. Remarks: The linked list of ON_MeshXPoint will contain duplicate locations where the intersection component crosses a shared edge. The JoinPoints() function requires the input values of m_p[] to be valid. Call RepairPrevNext() before calling JoinPoints() if you are running code outside of opennurbs that may have bugs that incorrectly set m_p[] values.

MaximumEventSerialNumber()

unsigned int ON_MeshXPointPool::MaximumEventSerialNumber

(

)

const

Returns: All event serial numbers are <= MaximumEventSerialNumber().

PointCount()

unsigned int ON_MeshXPointPool::PointCount

(

)

const

RepairPrevNext()

unsigned int ON_MeshXPointPool::RepairPrevNext

(

)

Description: If ValidatePrevNext() returns false, then RepairPrevNext() can be used to alter the m_p[] values so they make sense. Returns: Number of ON_MeshXPoint m_p[0] values that were set to zero.

ReturnAllPoints()

void ON_MeshXPointPool::ReturnAllPoints

(

)

ReturnPoint()

void ON_MeshXPointPool::ReturnPoint

(

ON_MeshXPoint *

)

SetAllTags()

void ON_MeshXPointPool::SetAllTags

(

ON__INT_PTR

tag

)

Description: Set every point's m_tag value to tag. Parameters: tag - [in] Remarks: This

ValidatePrevNext()

bool ON_MeshXPointPool::ValidatePrevNext

(

)

const

Returns: True if the ON_MeshXPoint.m_p[] values are correctly set.
