包路径：org.modeshape.jcr.api.Binary
类名称：Binary
方法名：getHexHash

Binary.getHexHash介绍

[英]Get the hexadecimal form of the SHA-1 hash of the contents. This hash can be used to determine whether two Binary instances contain the same content.

Repeatedly calling this method should generally be efficient, as it most implementations will compute the hash only once.
[中]获取内容的SHA-1哈希的十六进制形式。此哈希可用于确定两个二进制实例是否包含相同的内容。
重复调用此方法通常是有效的，因为大多数实现只会计算一次哈希。
