com.oss.util.BERTool.BERReader

Enclosing class:

BERTool

public static class BERTool.BERReader
extends java.lang.Object

Provides the readTLV() method to read a complete BER encoding from an input stream and return it as an array of bytes.

The class instance uses an internal byte buffer to acquire encoded bytes that are read from the input stream. The buffer is allocated with a default or specified size and is resized as needed to acquire the longest BER encoding across multiple invocations of the readTLV() method.
