      public com.io7m.jlexing.core.LexicalPosition<java.net.URI> lexical()
      Specified by:
      lexical in interface com.io7m.jlexing.core.LexicalType<java.net.URI>
      Specified by:
      lexical in interface ParseErrorType
      Returns:
      The value of the lexical attribute

    • severity

      public ParseErrorType.Severity severity()
      Specified by:
      severity in interface ParseErrorType
      Returns:
      The error severity

    • message

      public java.lang.String message()
      Specified by:
      message in interface ParseErrorType
      Returns:
      The error message

    • exception

      public java.util.Optional<java.lang.Exception> exception()
      Specified by:
      exception in interface ParseErrorType
      Returns:
      The exception raised, if any

    • withLexical

      public final ParseError withLexical​(com.io7m.jlexing.core.LexicalPosition<java.net.URI> value)
      Copy the current immutable object by setting a value for the lexical attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for lexical
      Returns:
      A modified copy of the this object

    • withSeverity

      public final ParseError withSeverity​(ParseErrorType.Severity value)
      Copy the current immutable object by setting a value for the severity attribute. A value equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for severity
      Returns:
      A modified copy of the this object

    • withMessage

      public final ParseError withMessage​(java.lang.String value)
      Copy the current immutable object by setting a value for the message attribute. An equals check used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for message
      Returns:
      A modified copy of the this object

    • withException

      public final ParseError withException​(java.lang.Exception value)
      Copy the current immutable object by setting a present value for the optional exception attribute.
      Parameters:
      value - The value for exception
      Returns:
      A modified copy of this object

    • withException

      public final ParseError withException​(java.util.Optional<? extends java.lang.Exception> optional)
      Copy the current immutable object by setting an optional value for the exception attribute. A shallow reference equality check is used on unboxed optional value to prevent copying of the same value by returning this.
      Parameters:
      optional - A value for exception
      Returns:
      A modified copy of this object

    • equals

      public boolean equals​(java.lang.Object another)
      This instance is equal to all instances of ParseError that have equal attribute values.
      Overrides:
      equals in class java.lang.Object
      Returns:
      true if this is equal to another instance

    • hashCode

      public int hashCode()
      Computes a hash code from attributes: lexical, severity, message, exception.
      Overrides:
      hashCode in class java.lang.Object
      Returns:
      hashCode value

    • toString

      public java.lang.String toString()
      Prints the immutable value ParseError with attribute values.
      Overrides:
      toString in class java.lang.Object
      Returns:
      A string representation of the value

    • copyOf

      public static ParseError copyOf​(ParseErrorType instance)
      Creates an immutable copy of a ParseErrorType value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.
      Parameters:
      instance - The instance to copy
      Returns:
      A copied immutable ParseError instance

    • builder

      public static ParseError.Builder builder()
      Creates a builder for ParseError. 
       ParseError.builder()
    .setLexical(com.io7m.jlexing.core.LexicalPosition&lt;java.net.URI&gt;) // required lexical
    .setSeverity(com.io7m.coffeepick.runtime.parser.spi.ParseErrorType.Severity) // required severity
    .setMessage(String) // required message
    .setException(Exception) // optional exception
    .build();
      Returns:
      A new ParseError builder
