Field Detail

CONSUMER

public static final java.lang.String CONSUMER

The consumer property. It is associated with productions, has a boolean value, and indicates whether a production may consume the input.

Constant Field Values

COST

public static final java.lang.String COST

The cost property. It is associated with productions, has an integer value, and indicates a production's estimated cost for inlining.

See Also:

Constant Field Values

DUPLICATES

public static final java.lang.String DUPLICATES

The duplicates property. It is associated with productions, has a list of strings value, and indicates the names of the original productions folded into the annotated one.

See Also:

Constant Field Values

EMPTY

public static final java.lang.String EMPTY

The empty property. It is associated with productions, has a boolean value, and indicates whether a production may match the empty input.

See Also:

Constant Field Values

GENERIC

public static final java.lang.String GENERIC

The generic property. When associated with a production, it has a GENERIC_NODE value indicating that the production's semantic value is a generic node with the component values as its children or a GENERIC_RECURSION value indicating that the production's value is the result of a left-recursive production. When associated with a grammar, it has boolean value indicating whether the grammar contains generic nodes.

See Also:

Constant Field Values

GENERIC_NODE

public static final java.lang.String GENERIC_NODE

The generic node value.

See Also:

Constant Field Values

GENERIC_RECURSION

public static final java.lang.String GENERIC_RECURSION

The generic recursion value.

See Also:

Constant Field Values

FORMATTING

public static final java.lang.String FORMATTING

The formatting property. It is associated with sequences, has a list of bindings as its value, and indicates that a recursive alternative in a directly left-recursive generic production has formatting annotations for the node generated by the promise.

See Also:

Constant Field Values

LEXICAL

public static final java.lang.String LEXICAL

The lexical property. It is associated with productions, has a boolean value, and indicates whether a production recognizes lexical syntax.

See Also:

Constant Field Values

LOCATABLE

public static final java.lang.String LOCATABLE

The locatable property. It is associated with a grammar, has a boolean value, and indicates whether the corresponding parser uses the locatable interface.

See Also:

Constant Field Values

META_DATA

public static final java.lang.String META_DATA

The meta-data property. It is associated with productions and has a MetaData value containing a production's meta-data.

See Also:

Constant Field Values

OPTION

public static final java.lang.String OPTION

The option property. It is associated with productions, has a boolean value, and indicates whether a production represents a desugared option.

See Also:

Constant Field Values

RECURSIVE

public static final java.lang.String RECURSIVE

The recursive property. It is associated with grammars, has a boolean value, and indicates that a grammar contains directly left-recursive generic productions. It is also associated with productions and indicates that a production is left-recursive.

See Also:

Constant Field Values

REDACTED

public static final java.lang.String REDACTED

The redacted property. It is associated with productions, has a boolean value, and indicates that a production's body has been removed even though the production really has a body.

See Also:

Constant Field Values

REPEATED

public static final java.lang.String REPEATED

The repeated property. It is associated with productions, has a nonterminal value, and indicates that a production represents a desguared repetition whose element value is the value of the nonterminal.

See Also:

Constant Field Values

RESTRICT

public static final java.lang.String RESTRICT

The restrict property. It is associated with productions, has a boolean value, and indicates whether a production restricts the input.

See Also:

Constant Field Values

ROOT

public static final java.lang.String ROOT

The root property. It is associated with grammars, has a nonterminal value, and indicates a grammar's real root (i.e., the single public production that directly or indirectly references all other public productions).

See Also:

Constant Field Values

SPLIT

public static final java.lang.String SPLIT

The split property. It is associated with productions, has a boolean value, and indicates that the production's alternatives need to be split. It is also associated with sequences, has a Annotator.IndexPair value, and indicates how to split the sequence.

See Also:

Constant Field Values

TEXT_ONLY

public static final java.lang.String TEXT_ONLY

The token property. It is associated with productions, has a boolean value, and indicates whether a production represents a lexical token.

See Also:

Constant Field Values

TRANSFORMABLE

public static final java.lang.String TRANSFORMABLE

The transformable property. It is associated with productions, has a boolean value, and indicates whether a production is a directly left-recursive production that can be transformed into an equivalent right-recursive or -iterative production.

See Also:

Constant Field Values

VOIDED
