|
43 * First, this file contains the VM-related functions needed by native |

|
46 * |
|
47 * Second, this file contains the functions and constant definitions |
|
48 * needed by the byte code verifier and class file format checker. |
|
49 * These functions allow the verifier and format checker to be written |
|
50 * in a VM-independent way. |
|
51 * |
|
52 * Third, this file contains various I/O and network operations needed |
|
53 * by the standard Java I/O and network APIs. |
