DerInputBuffer

DER input buffer ... this is the main abstraction in the DER library which actively works with the "untyped byte stream" abstraction. It does so with impunity, since it's not intended to be exposed to anyone who could violate the "typed value stream" DER model and hence corrupt the input stream of DER values.

dup DerInputBuffer dup(): Undocumented in source. Be warned that the author may not have intended to support it.
equals bool equals(DerInputBuffer other): Undocumented in source. Be warned that the author may not have intended to support it.
getBigInteger BigInteger getBigInteger(int len, bool makePositive): Returns the integer which takes up the specified number of bytes in this buffer as a BigInteger. @param len the number of bytes to use. @param makePositive whether to always return a positive value, irrespective of actual encoding @return the integer as a BigInteger.
getBitString byte[] getBitString(int len): Returns the bit string which takes up the specified number of bytes in this buffer.
getBitString byte[] getBitString(): Returns the bit string which takes up the rest of this buffer.
getInteger int getInteger(int len): Returns the integer which takes up the specified number of bytes in this buffer. @throws IOException if the result is not within the valid range for integer, i.e. between int.min and int.max. @param len the number of bytes to use. @return the integer.
getUnalignedBitString BitArray getUnalignedBitString(): Returns the bit string which takes up the rest of this buffer. The bit string need not be byte-aligned.
opEquals bool opEquals(Object other): Compares this DerInputBuffer for equality with the specified object.
peek int peek(): Undocumented in source. Be warned that the author may not have intended to support it.
toByteArray byte[] toByteArray(): Undocumented in source. Be warned that the author may not have intended to support it.
toHash size_t toHash(): Returns a hashcode for this DerInputBuffer.
truncate void truncate(int len): Undocumented in source. Be warned that the author may not have intended to support it.
