Method Detail

copy

public SubexpressionCall 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 QuantifiableTerm

Parameters:

ast - RegexAST the node should belong to.

Returns:

A shallow copy of this node.

copyRecursive

public SubexpressionCall 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.

getParent

public Sequence getParent()

Description copied from class: RegexASTNode

Gets the syntactic parent of this AST node.

Overrides:

getParent in class RegexASTNode

getGroupNr

public int getGroupNr()

Returns the capture group number this subexpression call is referring to, e.g. the referenced group of \g<1> is 1.

isUnrollingCandidate

public boolean isUnrollingCandidate()

Description copied from class: QuantifiableTerm

Returns true iff the parser should try to unroll this term's quantifier.

Specified by:

isUnrollingCandidate in class QuantifiableTerm

equalsSemantic

public boolean equalsSemantic(RegexASTNode obj,
                              boolean ignoreQuantifier)

Specified by:

equalsSemantic in class QuantifiableTerm

toString

public String toString()

Overrides:

toString in class Object

toJson

public JsonValue toJson()
