Strings
CNI provides a number of utility functions for
working with Java Java String
objects.
The names and interfaces are analogous to those of JNI.
jstring JvNewString (const char* chars, jsize len)
|
Function |
Returns a Java String object with characters from the C string
chars up to the index len in that array.
|
jstring JvNewStringLatin1 (const char* bytes, jsize len)
|
Function |
Returns a Java String made up of len bytes from bytes.
|
jstring JvNewStringLatin1 (const char* bytes)
|
Function |
As above but the length of the String is strlen(bytes) .
|
jstring JvNewStringUTF (const char* bytes)
|
Function |
Returns a String which is made up of the UTF encoded characters
present in the C string bytes.
|
jchar* JvGetStringChars (jstring str)
|
Function |
Returns a pointer to an array of characters making up the String str.
|
int JvGetStringUTFLength (jstring str)
|
Function |
Returns the number of bytes required to encode the contents of the
String str in UTF-8.
|
jsize JvGetStringUTFRegion (jstring str, jsize start, jsize len, char* buf)
|
Function |
Puts the UTF-8 encoding of a region of the String str into
the buffer buf . The region to fetch is marked by start and len.
Note that buf is a buffer, not a C string. It is not
null terminated.
