Detailed Description

class VNode accesses nodes in the results set directly from the PropertySet and not from the Property

Member Function Documentation

data_t afl::ddf::VNode::get (  property_t  prop, size_t  row = 0, size_t  col = 0, size_t  epoch = 0 )  const

returns a value from a particular node and property Parameters: prop  the name of the property that will be affected row  selects the row col  selects the column epoch  selects the epoch Returns: the stored datum at the corresponding location Exceptions: OutOfBoundsException  if the property doesn't exist or the value of either of row, col and epoch is too large.

VNode& afl::ddf::VNode::operator= (  const VNode &  toCopy  )

Parameters: toCopy  a VNode to mimic

void afl::ddf::VNode::set (  data_t  datum, property_t  prop, size_t  row = 0, size_t  col = 0, size_t  epoch = 0 )

sets a value at a particular node and property Parameters: prop  the name of the property this operation will affect datum  the value to store row  selects the row col  selects the column epoch  selects the epoch Exceptions: OutOfBoundsException  if the property doesn't exist or the value of either of row, col and epoch is too large.
