Constructor & Destructor Documentation

eval::FunctionOperationNode::FunctionOperationNode

(

const node_ptr &

enclosed

)

Creates a new Function operation which simply does nothing.

Can only have one subexpression

Definition at line 41 of file function_operation_node.cpp.

eval::FunctionOperationNode::FunctionOperationNode	(	op::FunctionEnum	operation,
		const std::vector< node_ptr > &	enclosed
	)

Creates a new function operation with a certain operation and any number of subexpressions.

Note

Even you can pass any number of subexpressions, some operations need a certain number ob expressions!

Parameters

operation	executed by this node
enclosed	expressions evaluated by this node to execute the operation

Definition at line 56 of file function_operation_node.cpp.

Member Function Documentation

string eval::FunctionOperationNode::eval ( GeoObject *  obj ) const

virtual

Evaluates a subtree under this node.

Parameters

obj	which is used to execute the eval tree

Reimplemented from eval::STNode.
