 Assign primitive to node (when building a tree). The default behaviour just returns the same pointer (common primitives). ERC's should override and generate a new object with a new value.

Detailed Description

Base primitive class (Tree genotype).

Each node of a tree points to a single primitive, which may be a function or a variable (of Terminal class). Some primitives are shared among all the trees (i.e. have the same value and functionality), but some (like ERC) are owned by a single Tree.

PrimitiveP Tree::Primitives::Primitive::assignToNode ( PrimitiveP  primitive  )  [virtual]

Assign primitive to node (when building a tree). The default behaviour just returns the same pointer (common primitives). ERC's should override and generate a new object with a new value.

Parameters:
sptr to this primitive

Reimplemented in Tree::Primitives::ERC< T >, Tree::Primitives::ERCD, and Tree::Primitives::ERC< double >.

Definition at line 36 of file Primitive.cpp.

PrimitiveP Tree::Primitives::Primitive::copyWithNode ( PrimitiveP  primitive  )  [virtual]

Copy primitive (when copying a node, e.g. in crossover). The default behaviour just returns the same pointer (common primitives). (ERC's should override and make a new copy of the original object).

Parameters:
sptr to this primitive

Reimplemented in Tree::Primitives::ERC< T >, and Tree::Primitives::ERC< double >.

Definition at line 60 of file Primitive.cpp.

void Tree::Primitives::Primitive::getNextArgument ( void *  result,
Tree tree 
)

Execute next child node's primitive (execute next subtree).

Parameters:
result result of the operation
tree reference to current tree

Definition at line 71 of file Primitive.cpp.

void Tree::Primitives::Primitive::skipNextArgument ( Tree tree  ) 

Skip next child subtree (doesn't execute the subtree).

Parameters:
tree reference to current tree

Definition at line 82 of file Primitive.cpp.
