描述

算子 compare_memory_blockcompare_memory_blockCompareMemoryBlockCompareMemoryBlockCompareMemoryBlockcompare_memory_block compares the contents of two memory block tuples and returns the comparison result in IsEqualIsEqualIsEqualIsEqualisEqualis_equal. Therefore, each memory block in the tuple MemoryBlocks1MemoryBlocks1MemoryBlocks1MemoryBlocks1memoryBlocks1memory_blocks_1 is compared to the respective block in the tuple MemoryBlocks2MemoryBlocks2MemoryBlocks2MemoryBlocks2memoryBlocks2memory_blocks_2 with the same index. IsEqualIsEqualIsEqualIsEqualisEqualis_equal is set to TRUE if the number of elements of the two tuples matches and if the length and byte content of each pair of memory blocks coincides, otherwise to FALSE.

注意

Note that compare_memory_blockcompare_memory_blockCompareMemoryBlockCompareMemoryBlockCompareMemoryBlockcompare_memory_block compares the memory blocks regarding their actual byte content, not their location in memory.
