Constants.js

/**
 * The (primary) property that describes the content of a selection
 * node's data. Other auxiliary description properties follow.
 * GLOBALIDS means that the selection list contains values from the
 * vtkDataSetAttribute array of the same name.
 * PEDIGREEIDS means that the selection list contains values from the
 * vtkDataSetAttribute array of the same name.
 * VALUES means the the selection list contains values from an
 * arbitrary attribute array (ignores any globalids attribute)
 * INDICES means that the selection list contains indexes into the
 * cell or point arrays.
 * FRUSTUM means the set of points and cells inside a frustum
 * LOCATIONS means the set of points and cells near a set of positions
 * THRESHOLDS means the points and cells with values within a set of ranges
 * getContentType() returns -1 if the content type is not set.
