Method Detail

copy

public RegexASTSubtreeRootNode copy(RegexAST ast)

Description copied from class: RegexASTNode

Copy this node only, without any child nodes. The ID and minPath of the copied nodes is left unset.

Specified by:

copy in class RegexASTSubtreeRootNode

Parameters:

ast - RegexAST the node should belong to.

Returns:

A shallow copy of this node.

copyRecursive

public Term copyRecursive(RegexAST ast,
                          CompilationBuffer compilationBuffer)

Description copied from class: RegexASTNode

Recursively copy this subtree. This method should be used instead of CopyVisitor if the copying process is required to be thread-safe. The ID and minPath of the copied nodes is left unset.

Specified by:

copyRecursive in class Term

Parameters:

ast - RegexAST the new nodes should belong to.

Returns:

A deep copy of this node.

getEnclosedCaptureGroupsLow

public int getEnclosedCaptureGroupsLow()

Gets the (inclusive) lower bound of the range of capture groups contained within this group.

getEnclosedCaptureGroupsHigh

public int getEnclosedCaptureGroupsHigh()

Gets the (exclusive) upper bound of the range of capture groups contained within this group.

getPrefix

public String getPrefix()

Specified by:

getPrefix in class RegexASTSubtreeRootNode

equalsSemantic

public boolean equalsSemantic(RegexASTNode obj)

Specified by:

equalsSemantic in class RegexASTNode

toJson

public JsonValue toJson()
