fun <T> ParseTreeToASTTransformer.translateCasted(original: ParserRuleContext): T

Translate the given node and ensure a certain type will be obtained.

fun <T> ParseTreeToASTTransformer.translateList(original: Collection<out ParserRuleContext>?): ObservableList<T>

Translate a whole collection into a mutable list, translating each element and ensuring the list has the expected type.

Link copied to clipboard
fun <T> ParseTreeToASTTransformer.translateOnlyChild(parent: ParserRuleContext): T

Translate the only child (of type ParseRuleContext) and ensure the resulting value as the expected type.

Link copied to clipboard
fun <T> ParseTreeToASTTransformer.translateOptional(original: ParserRuleContext?): T?

Translate the given node and ensure a certain type will be obtained, if the value is not null. If the value is null, null is returned.
