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 and 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.
