类 Asn1BerParser

java.lang.Object

net.dongliu.apk.parser.cert.asn1.Asn1BerParser

public final class Asn1BerParser
extends Object

Parser of ASN.1 BER-encoded structures.

Structure is described to the parser by providing a class annotated with Asn1Class, containing fields annotated with Asn1Field.

方法概要

限定符和类型	方法和说明
static <T> T	parse(ByteBuffer encoded, Class<T> containerClass) Returns the ASN.1 structure contained in the BER encoded input.
static <T> List<T>	parseImplicitSetOf(ByteBuffer encoded, Class<T> elementClass) Returns the implicit SET OF contained in the provided ASN.1 BER input.

方法详细资料

parse

public static <T> T parse(ByteBuffer encoded,
                          Class<T> containerClass)
                   throws Asn1DecodingException

Returns the ASN.1 structure contained in the BER encoded input.

参数:

encoded - encoded input. If the decoding operation succeeds, the position of this buffer is advanced to the first position following the end of the consumed structure.

containerClass - class describing the structure of the input. The class must meet the following requirements:

• The class must be annotated with Asn1Class.
• The class must expose a public no-arg constructor.
• Member fields of the class which are populated with parsed input must be annotated with Asn1Field and be public and non-final.

抛出:

Asn1DecodingException - if the input could not be decoded into the specified Java object

parseImplicitSetOf

public static <T> List<T> parseImplicitSetOf(ByteBuffer encoded,
                                             Class<T> elementClass)
                                      throws Asn1DecodingException

Returns the implicit SET OF contained in the provided ASN.1 BER input. Implicit means that this method does not care whether the tag number of this data structure is SET OF and whether the tag class is UNIVERSAL.

Note: The returned type is List rather than Set because ASN.1 SET may contain duplicate elements.

参数:

encoded - encoded input. If the decoding operation succeeds, the position of this buffer is advanced to the first position following the end of the consumed structure.

elementClass - class describing the structure of the values/elements contained in this container. The class must meet the following requirements:

• The class must be annotated with Asn1Class.
• The class must expose a public no-arg constructor.
• Member fields of the class which are populated with parsed input must be annotated with Asn1Field and be public and non-final.

抛出:

Asn1DecodingException - if the input could not be decoded into the specified Java object
