Member Function Documentation

virtual void Source::resolve

(

Point *

p

)

[pure virtual]

Resolve a given Point by filling it with any new data this source can provide. Will ignore given point if this source can't provide data.

Parameters:

p

The point to try filling with data

Implemented in SourceInteger, SourceGridFloat, and SourceGroup.

void Source::resolveList

(

vector< Point * >

list

)

Resolve the entire list of Point objects by calling resolve() on each of them.

Parameters:

list

List of Point objects to try resolving

virtual bool Source::contains

(

Point *

p

)

[virtual]

Check if this source provides data about the given point.

Parameters:

p

Point to check against

Returns:

True if this source provides data about given point, otherwise false.

Reimplemented in SourceGroup.
