| Modifier and Type | Method and Description |
|---|---|
static ByteBuffer |
copy(ByteBuffer src,
ByteBuffer dest)
拷贝 ByteBuffer
|
static ByteBuffer |
copy(ByteBuffer src,
ByteBuffer dest,
int length)
拷贝 ByteBuffer
|
static ByteBuffer |
copy(ByteBuffer src,
int srcStart,
ByteBuffer dest,
int destStart,
int length)
拷贝 ByteBuffer
|
static ByteBuffer |
copy(ByteBuffer src,
int start,
int end)
拷贝到一个新的 ByteBuffer
|
static ByteBuffer |
create(byte[] data)
创建新 Buffer
|
static ByteBuffer |
create(String data)
从字符串创建新 Buffer
|
static int |
lineEnd(ByteBuffer buffer)
一行的末尾位置 查找位置时位移 ByteBuffer 到结束位置
|
static int |
lineEnd(ByteBuffer buffer,
int maxLength)
一行的末尾位置 查找位置时位移 ByteBuffer 到结束位置
|
static byte[] |
readBytes(ByteBuffer buffer)
读取剩余部分 bytes
|
static byte[] |
readBytes(ByteBuffer buffer,
int maxLength)
读取指定长度的 bytes
如果长度不足则读取剩余部分 此时buffer必须为读模式 |
static byte[] |
readBytes(ByteBuffer buffer,
int start,
int end)
读取指定区间的数据
|
static String |
readLine(ByteBuffer buffer)
读取一行 如果 buffer 中最后一部分并非完整一行则返回 null
|
static String |
readStr(ByteBuffer buffer)
读取剩余部分并转为字符串
