public interface ASN1Reader extends Closeable
An interface for decoding ASN.1 elements from a data source.

Methods for creating ASN1Readers are provided in the ASN1 class.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    close()
    Closes this ASN.1 reader.
    boolean
    elementAvailable()
    Indicates whether the next element can be read without blocking.
    boolean
    hasNextElement()
    Indicates whether the current stream, sequence, or set contains another element.
    int
    peekLength()
    Returns the data length of the next element without actually reading it.
    byte
    peekType()
    Returns the type of the next element without actually reading it.
    boolean
    readBoolean()
    Reads the next element as a boolean having the Universal Boolean ASN.1 type tag.
    boolean
    readBoolean(byte type)
    Reads the next element as a boolean having the provided type tag.
    void
    readEndExplicitTag()
    Finishes reading an explicit tag and discards any unread elements.
    void
    readEndSequence()
    Finishes reading a sequence and discards any unread elements.
    void
    readEndSet()
    Finishes reading a set and discards any unread elements.
    int
    readEnumerated()
    Reads the next element as an enumerated having the Universal Enumerated ASN.1 type tag.
    int
    readEnumerated(byte type)
    Reads the next element as an enumerated having the provided type tag.
    long
    readInteger()
    Reads the next element as an integer having the Universal Integer ASN.1 type tag.
    long
    readInteger(byte type)
    Reads the next element as an integer having the provided type tag.
    void
    readNull()
    Reads the next element as a null element having the Universal Null ASN.1 type tag.
    void
    readNull(byte type)
    Reads the next element as a null element having the provided type tag.
    ByteString
    readOctetString()
    Reads the next element as an octet string having the Universal Octet String ASN.1 type tag.
    ByteString
    readOctetString(byte type)
    Reads the next element as an octet string having the provided type tag.
    ByteStringBuilder
    readOctetString(byte type, ByteStringBuilder builder)
    Reads the next element as an octet string having the provided type tag and appends it to the provided ByteStringBuilder.
    ByteStringBuilder
    readOctetString(ByteStringBuilder builder)
    Reads the next element as an octet string having the Universal Octet String ASN.1 type tag and appends it to the provided ByteStringBuilder.
    String
    readOctetStringAsString()
    Reads the next element as an octet string having the Universal Octet String ASN.1 type tag and decodes the value as a UTF-8 encoded string.
    String
    readOctetStringAsString(byte type)
    Reads the next element as an octet string having the provided type tag and decodes the value as a UTF-8 encoded string.

    void
    readStartExplicitTag(byte type)
    Reads the next element as an explicit tag having the provided tag type.
    void
    readStartSequence()
    Reads the next element as a sequence having the Universal Sequence ASN.1 type tag.
    void
    readStartSequence(byte type)
    Reads the next element as a sequence having the provided type tag.

    void
    readStartSet(byte type)
    Reads the next element as a set having the provided type tag.
    ASN1Reader
    skipElement()
    Skips the next element without decoding it.
    ASN1Reader
    skipElement(byte type)
    Skips the next element having the provided type tag without decoding it.
