read
Reads a long form this source in hexadecimal form (i.e., as a string in base 16). This will iterate until a non-hexadecimal character is found.
Buffer buffer = new Buffer()
.writeUtf8("ffff CAFEBABE 10");
assertEquals(65535L, buffer.readHexadecimalUnsignedLong());
assertEquals(' ', buffer.readByte());
assertEquals(0xcafebabeL, buffer.readHexadecimalUnsignedLong());
assertEquals(' ', buffer.readByte());
assertEquals(0x10L, buffer.readHexadecimalUnsignedLong());Content copied to clipboard
Throws
if the found hexadecimal does not fit into a long or hexadecimal was not found.
