java.lang.Objectorg.apache.asn1.ber.digester.AbstractRule
org.apache.asn1.ber.digester.rules.PrimitiveBooleanRule
A rule to Decode a BER encoded ASN.1 INTEGER into a Java primitive int.
The bytes to form the integer are extracted from the BER value which may arrive in multiple chunks. The individual bytes are temporarily stored within a 4 byte array while incrementing a counter to track the capture. Once gathered the bytes are decoded into a int in the finish
As a side effect once the decode is complete, the primitive value is pushed onto the primitive int stack to be utilized by other rules later. If there is a loss of precision where the ASN.1 INTEGER is larger or smaller than the maximum or minimum value of a Java primitive integer an exception is thrown.
