java.lang.Object

de.aristaflow.adept2.core.changeoperations.CreateSurroundingBlock

public class CreateSurroundingBlock
extends Object

This change operation offers the possibility to surround nodes with a block of the following types:

• AND-Split -> AND-Join
• XOR-Split -> XOR-Join
• LOOP-Start -> LOOP-End

Call isPossible first to check if the insertion of the surrounding block is valid, than call perform operation to execute the change. TODO Refactor; use a common interface for change operations.

Method Detail

isPossible

public static boolean isPossible(Template template,
                                 Node first,
                                 Node last,
                                 ProcessConstants.BlockType type)

Check if it is possible (concerning structural correctness) to create a block which surrounds the two given nodes in the given template.

Parameters:

template - The template where the method is performed on.

first - the first node of the block

last - the last node of the block

type - the BlockType

Returns:

True, if the insertion is possible.

isPossible

public static boolean isPossible(Template template,

Check if it is possible (concerning structural correctness) to create a block which surrounds the two given nodes in the given template. If the check fails the reason is stored in the given chechReport (provided that checkReport is not null)

Parameters:
