initialiseParse

@ParametersAreNonnullByDefault
protected void initialiseParse(Reader input,
 String baseUri,
 Parser parser)

toString

public String toString()

Overrides:

toString in class Object

isContentForTagData

protected boolean isContentForTagData(String normalName)

the last element on the stack, if any; or the root document

currentElementIs

protected boolean currentElementIs(String normalName)

Parameters:

normalName - name to check

true if there is a current element on the stack, and its name equals the supplied

error

protected void error(String msg)

onNodeInserted

protected void onNodeInserted(Node node,
 @Nullable
 org.jsoup.parser.Token token)

Called by implementing TreeBuilders when a node has been inserted. This implementation includes optionally tracking the source range of the node.

Parameters:

node - the node that was just inserted

token - the (optional) token that created this node

onNodeClosed

protected void onNodeClosed(Node node,
 org.jsoup.parser.Token token)
