Method Detail

copy

public RegexASTSubtreeRootNode copy(RegexAST ast,
                                    boolean recursive)

Description copied from class: RegexASTNode

Copy this node, in one of the following ways:

• if recursive is true, recursively copy this subtree. This method should be used instead of CopyVisitor if the copying process is required to be thread-safe.
• else, copy this node only, without any child nodes.

In both cases, the ID and minPath of the copied nodes is left unset.

Specified by:

copy in class RegexASTSubtreeRootNode

Parameters:

ast - RegexAST the new nodes should belong to.

Returns:

A shallow or deep copy of this node.

getPrefix

public String getPrefix()

Specified by:

getPrefix in class RegexASTSubtreeRootNode

equalsSemantic

public boolean equalsSemantic(RegexASTNode obj,
                              boolean ignoreQuantifier)

Specified by:

equalsSemantic in class Term

toString

public String toString()

Overrides:

toString in class RegexASTSubtreeRootNode

toJson

public JsonValue toJson()
