构造器详细资料

TypedKey

public TypedKey(Object val,
                DataType type,
                int prefixLength)

方法详细资料

toTypedKey

public static TypedKey toTypedKey(Object val,
                                  DataType type,
                                  int prefixLength)

Map a typed value into TypedKey, only encoding first prefixLength bytes

When prefixLength is DataType.UNSPECIFIED_LEN, encode full length of value

参数:

val - value

type - type of value

prefixLength - described above

返回:

an encoded TypedKey

toTypedKey

public static TypedKey toTypedKey(Object val,
                                  DataType type)

getType

public DataType getType()

getValue

public Object getValue()

nextPrefix

public TypedKey nextPrefix()

从类复制的说明: Key

nextPrefix key will be key with next available rid. For example, if the current key is prefix_rid, after calling this method, the return value should be prefix_rid+1

覆盖:

nextPrefix 在类中 Key

返回:

a new key current rid+1.

next

public TypedKey next()

Next TypedKey be truncated with prefixLength

覆盖:

next 在类中 Key

返回:

next TypedKey with same prefix length

toString

public String toString()

覆盖:

toString 在类中 Key
