至于其他情况,如果传入的数据类型(实际参数类型)小于方法中声明的形式参数类型,实际数据类型就会被提升。char型略有不同,如果无法找到恰好接受char参数的方法,就会把char直接提升至int型。 如果传入的实际参数大于重载方法声明的形式参数,会出现什么情况呢? 在这里,方法接受较小的基本类型作为参数。如果传入的实际参数较...

The library automatically converts between Java Strings and their FITS representations, by the appropriate narrowing conversion of 16-bit Unicode char to byte. Therefore, you should be careful to avoid using extended Unicode characters (and also ASCII beyond the 0x20 -- 0x7E range) in Strings, ...

For byte buffer, you can allocate a directByteBuffervia theallocateDirect(int capacity)method. For other buffers (char, short, int, long, float, double), you need to first allocate aByteBuffer, and then create aviewvia methods such asasFloatBuffer(). As these primitive types have unit of mu...

TheMat5class contains static factory methods that serve as the starting points for the public API. The basic types (e.g.Struct,Cell,Sparse,Char) follow their corresponding MATLAB semantics (e.g. a struct can’t be logical) and provide a fluent API for the most common use cases. All of...
