in ParserCreationException.cs

The error type enumeration.

Field Summary
`INFINITE_LOOP` The infinite loop error type is used when an infinite loop has been detected in the grammar.
`INHERENT_AMBIGUITY` The inherent ambiguity error type is used when the set of production patterns (i.e. the grammar) contains ambiguities that cannot be resolved.
`INTERNAL` The internal error type is only used to signal an error that is a result of a bug in the parser or tokenizer code.
`INVALID_PARSER` The invalid parser error type is used when the parser as such is invalid.
`INVALID_PRODUCTION` The invalid production error type is used when a production pattern is erroneous.
`INVALID_TOKEN` The invalid token error type is used when a token pattern is erroneous.

Field Detail

INFINITE_LOOP

public INFINITE_LOOP

The infinite loop error type is used when an infinite loop has been detected in the grammar. One of the productions in the loop will be reported.

INHERENT_AMBIGUITY

public INHERENT_AMBIGUITY

The inherent ambiguity error type is used when the set of production patterns (i.e. the grammar) contains ambiguities that cannot be resolved.

INTERNAL

public INTERNAL

The internal error type is only used to signal an error that is a result of a bug in the parser or tokenizer code.

INVALID_PARSER

public INVALID_PARSER

The invalid parser error type is used when the parser as such is invalid. This error is typically caused by using a parser without any patterns.

INVALID_PRODUCTION

public INVALID_PRODUCTION

The invalid production error type is used when a production pattern is erroneous. This error is typically caused by referencing undeclared productions, or violating some other production pattern constraint.

INVALID_TOKEN

public INVALID_TOKEN

The invalid token error type is used when a token pattern is erroneous. This error is typically caused by an invalid pattern type or an erroneous regular expression.
