Field Details

INSTANCE

public static final EsqlParser INSTANCE

MAX_LENGTH

public static final int MAX_LENGTH

Maximum number of characters in an ESQL query. Antlr may parse the entire query into tokens to make the choices, buffering the world. There's a lot we can do in the grammar to prevent that, but let's be paranoid and assume we'll fail at preventing antlr from slurping in the world. Instead, let's make sure that the world just isn't that big.
