Class CompositeParser<T>

java.lang.Object

software.amazon.awssdk.codegen.jmespath.parser.util.CompositeParser<T>

All Implemented Interfaces:

Parser<T>

public final class CompositeParser<T>
extends Object
implements Parser<T>

A Parser that invokes a list of converters, returning the first converter that was successful. This is created using firstTry(Parser) and new converters are added via thenTry(Parser).

Method Summary

Modifier and Type	Method	Description
static <T> CompositeParser<T>	firstTry(Parser<T> parser)	Create a CompositeParser that tries the provided parser first.
static <T, U> CompositeParser<U>	firstTry(Parser<T> parser, Function<T,U> resultConverter)	Create a CompositeParser that tries the provided parser first, converting the result of that parser using the provided function.
ParseResult<T>	parse(int startPosition, int endPosition)	Parse a JMESPath string between the start position (inclusive) and end position (exclusive).
<S> CompositeParser<T>	thenTry(Parser<S> nextParser, Function<S,T> resultConverter)	Create a new CompositeParser that tries the provided parser after all previous parsers, converting the result of that parser using the provided function.
CompositeParser<T>	thenTry(Parser<T> nextParser)	Create a new CompositeParser that tries the provided parser after all previous parsers.
