Class WebClient.PooledCSS3Parser

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.htmlunit.cssparser.parser.javacc.CSS3ParserConstants
    Enclosing class:
    WebClient
    public static class WebClient.PooledCSS3Parser
extends org.htmlunit.cssparser.parser.javacc.CSS3Parser
implements java.lang.AutoCloseable
    This is a poolable CSS3Parser which can be reused automatically when closed. A regular CSS3Parser is not thread-safe, hence also our pooled parser is not thread-safe. INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.

      • PooledCSS3Parser

        protected PooledCSS3Parser​(org.htmlunit.WebClient.CSS3ParserPool pool)
        Create a new poolable parser.
        Parameters:
        pool - the pool the parser should return to when it is closed

    • Method Detail

      • markInUse

        protected WebClient.PooledCSS3Parser markInUse​(org.htmlunit.WebClient.CSS3ParserPool pool)
        Resets the parser's pool state so it can be safely returned again.
        Parameters:
        pool - the pool the parser should return to when it is closed
        Returns:
        this parser for fluid programming

      • close

        public void close()
        Implements the AutoClosable interface. The return method ensures that we are notified when we incorrectly close it twice which indicates a programming flow defect.
        Specified by:
        close in interface java.lang.AutoCloseable
        Throws:
        java.lang.IllegalStateException - in case the parser is closed several times
