Class URCapProgramNodeInterfaceVisitor<URCAP_PROGRAM_NODE_INTERFACE>

java.lang.Object

com.ur.urcap.api.domain.program.structure.ProgramNodeVisitor

com.ur.urcap.api.domain.program.structure.URCapProgramNodeInterfaceVisitor<URCAP_PROGRAM_NODE_INTERFACE>

Type Parameters:

URCAP_PROGRAM_NODE_INTERFACE - The interface a URCap ProgramNodeContribution also implements. Do not use ProgramNodeContribution (or an extension/implementation thereof) nor Object, otherwise an IllegalArgumentException is thrown when a URCap program node is encountered during traversal.

public abstract class URCapProgramNodeInterfaceVisitor<URCAP_PROGRAM_NODE_INTERFACE>
extends ProgramNodeVisitor

The URCapProgramNodeInterfaceVisitor is used in conjunction with the TreeNode.traverse(ProgramNodeVisitor) to visit all nodes in the sub-tree under the node on which TreeNode.traverse(com.ur.urcap.api.domain.program.structure.ProgramNodeVisitor) is called. The (generic) type parameter must be an interface that a URCap ProgramNodeContribution also implements. The visitURCapAs(URCAP_PROGRAM_NODE_INTERFACE, int, int) will be called when such a program node is encountered. All the visit-methods in the ProgramNodeVisitor superclass can still be overridden and will be called as usual. See also URCapProgramNode.getAs(java.lang.Class<T>).

Method Detail

visitURCapAs

public abstract void visitURCapAs(URCAP_PROGRAM_NODE_INTERFACE urCapProgramNode,
                                  int index,
                                  int depth)

This method is called whenever a URCap program node implementing the interface specified is encountered.

Parameters:

urCapProgramNode - The URCap program node represented as the interface specified.

index - Zero-based index among the program node's siblings (at this depth).

depth - Relative depth to the node calling the TreeNode.traverse(ProgramNodeVisitor) (calling node is at depth 0).
