示例1:
TEST(StringBuilderTest, ToAtomicString)
{
StringBuilder builder;
builder.append("123");
AtomicString atomicString = builder.toAtomicString();
EXPECT_EQ(String("123"), atomicString);
builder.reserveCapacity(256);
EXPECT_TRUE(builder.canShrink());
for (int i = builder.length(); i < 128; i++)
builder.append('x');
AtomicString atomicString1 = builder.toAtomicString();
EXPECT_EQ(128u, atomicString1.length());
EXPECT_EQ('x', atomicString1[127]);
// Later change of builder should not affect the atomic string.
for (int i = builder.length(); i < 256; i++)
builder.append('x');
EXPECT_EQ(128u, atomicString1.length());
EXPECT_FALSE(builder.canShrink());
String string = builder.toString();
AtomicString atomicString2 = builder.toAtomicString();
// They should share the same StringImpl.
EXPECT_EQ(atomicString2.impl(), string.impl());
}
