Document

Returns the cause of this throwable or null if the cause is nonexistent or unknown.

Usage

From source file:main.java.vasolsim.common.file.__NONUSEDREFERENCE_VaSOLSimExam.java

/**
 * This function uses the initialized ciphers to encrypt properties of the file. If any properties or questions are
 * updated, this function must be called in order to have access to the encrypted data prior to the write process.
 * This function is called by default at the start of the write function. NOTE: if the cryptographic key is
 * updated,/*from   w ww  . jav  a 2s  . com*/
 * updateCryptoEngine() must be called first or this function will encrypt the data based off of the old key.
 * Regardless, the write function will force everything to be updated prior to actually writing to avoid write
 * complications.
