Class DateTime

  • All Implemented Interfaces:

    public final class DateTime
    extends AbstractExpression
    This Expression represents a date or time. It supports the following identifiers:

    CURRENT_DATE: This function returns the value of current date on the database server.

    CURRENT_TIME: This function returns the value of current time on the database server.

    CURRENT_TIMESTAMP: This function returns the value of current timestamp on the database server.

    BNF: functions_returning_datetime ::= CURRENT_DATE | CURRENT_TIME | CURRENT_TIMESTAMP

    The JDBC escape syntax may be used for the specification of date, time, and timestamp literals.

    BNF: expression ::= {d 'yyyy-mm-dd'} | {t 'hh:mm:ss'} | {ts 'yyyy-mm-dd hh:mm:ss.f...'}

    • Method Detail

      • getActualIdentifier

        public java.lang.String getActualIdentifier()
        Returns the actual identifier found in the string representation of the JPQL query, which has the actual case that was used.
        The identifier that was actually parsed
      • getText

        public java.lang.String getText()
        Returns the encapsulated text of this AbstractExpression, which can be used in various ways, it can be a keyword, a literal, etc.
        getText in class AbstractExpression
        Either the JPQL identifier for this AbstractExpression, the literal it encapsulates or an empty string
      • isJDBCDate

        public boolean isJDBCDate()
        Determines whether this DateTime represents the JDBC escape syntax for date, time, timestamp formats.
        true if this Expression represents a JDBC escape syntax; false otherwise
      • parse

        protected void parse​(WordParser wordParser,
                             boolean tolerant)
        Parses the query by starting at the current position, which is part of the given WordParser.
        Specified by:
        parse in class AbstractExpression
        wordParser - The text to parse based on the current position of the cursor
        tolerant - Determines whether the parsing system should be tolerant, meaning if it should try to parse invalid or incomplete queries
      • toActualText

        public java.lang.String toActualText()
        Generates a string representation of this Expression, which needs to include any characters that are considered virtual, i.e. that was parsed when the query is incomplete and is needed for functionality like content assist.
        Specified by:
        toActualText in interface Expression
        toActualText in class AbstractExpression
        The string representation of this Expression
      • toParsedText

        protected void toParsedText​(java.lang.StringBuilder writer,
                                    boolean actual)
        Generates a string representation of this Expression, including its children, if it has any.
        Specified by:
        toParsedText in class AbstractExpression
        writer - The buffer used to append this Expression's string representation
        actual - Determines whether the string representation should represent what was parsed, i.e. include any "virtual" whitespace (such as ending whitespace) and the actual case of the JPQL identifiers
