    • isLiteral

      public boolean isLiteral()
      If it's literal text
      Returns:
      true if the String is literal (doesn't contain #{..} or ${..})

    • apply

      public ELText apply(jakarta.el.ExpressionFactory factory, jakarta.el.ELContext ctx)
      Return an instance of this that is applicable given the ELContext and ExpressionFactory state.
      Parameters:
      factory - the ExpressionFactory to use
      ctx - the ELContext to use
      Returns:
      an ELText instance

    • write

      public void write(Writer out, jakarta.el.ELContext ctx) throws jakarta.el.ELException, IOException
      Allow this instance to write to the passed Writer, given the ELContext state
      Parameters:
      out - Writer to write to
      ctx - current ELContext state
      Throws:
      jakarta.el.ELException - when an EL exception occurs
      IOException - when an I/O exception occurs

    • writeText

      public void writeText(ResponseWriter out, jakarta.el.ELContext ctx) throws jakarta.el.ELException, IOException
      Throws:
      jakarta.el.ELException
      IOException

    • toString

      public String toString(jakarta.el.ELContext ctx) throws jakarta.el.ELException
      Evaluates the ELText to a String
      Parameters:
      ctx - current ELContext state
      Returns:
      the evaluated String
      Throws:
      jakarta.el.ELException - when an EL exception occurs

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • isLiteral

      public static boolean isLiteral(String in)
      Parses the passed string to determine if it's literal or not
      Parameters:
      in - input String
      Returns:
      true if the String is literal (doesn't contain #{..} or ${..})

    • parse

      public static ELText parse(String in) throws jakarta.el.ELException
      Factory method for creating an unvalidated ELText instance. NOTE: All expressions in the passed String are treated as ELText.LiteralValueExpression, with one exception: composite component expressions. These are treated as ContextualCompositeValueExpressions.
      Parameters:
      in - String to parse
      Returns:
      ELText instance that knows if the String was literal or not
      Throws:
      jakarta.el.ELException - when an EL exception occurs

    • parse

      public static ELText parse(String in, String alias) throws jakarta.el.ELException
      Throws:
      jakarta.el.ELException

    • parse

      public static ELText parse(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in) throws jakarta.el.ELException
      Throws:
      jakarta.el.ELException

    • parse

      public static ELText parse(jakarta.el.ExpressionFactory fact, jakarta.el.ELContext ctx, String in, String alias) throws jakarta.el.ELException
      Factory method for creating a validated ELText instance. When an Expression is hit, it will use the ExpressionFactory to create a ValueExpression instance, resolving any functions at that time. Variables and properties will not be evaluated.
      Parameters:
      fact - ExpressionFactory to use
      ctx - ELContext to validate against
      in - String to parse
      alias - the alias
      Returns:
      ELText that can be re-applied later
      Throws:
      jakarta.el.ELException - when an EL exception occurs
