| BHSDCodec | | final public class BHSDCodec extends Codec (Code) | | TODO Comment -- quite a lot can be nicked from Codec, since this was created
from it
|
| Constructor Summary | |
| public | BHSDCodec(int b, int h)
Constructs an unsigned, non-delta Codec with the given B and H values. | | public | BHSDCodec(int b, int h, int s)
Constructs a non-delta Codec with the given B, H and S values. | | public | BHSDCodec(int b, int h, int s, int d)
Constructs a Codec with the given B, H, S and D values. |
| Method Summary | |
| public long | cardinality()
Returns the cardinality of this codec; that is, the number of distinct
values that it can contain. | | public long | decode(InputStream in)
| | public long | decode(InputStream in, long last)
| | public byte[] | encode(long value, long last)
| | public boolean | encodes(long value)
| | public int | getB()
| | public int | getH()
| | public int | getL()
| | public boolean | isDelta()
| | public boolean | isSigned()
| | public long | largest()
Returns the largest value that this codec can represent. | | public long | smallest()
Returns the smallest value that this codec can represent. | | public String | toString()
Returns the codec in the form (1,256) or (1,64,1,1). |
| BHSDCodec | | public BHSDCodec(int b, int h)(Code) | | Constructs an unsigned, non-delta Codec with the given B and H values.
Parameters:
b - the maximum number of bytes that a value can be encoded as[1..5]
Parameters:
h - the radix of the encoding [1..256] |
| BHSDCodec | | public BHSDCodec(int b, int h, int s)(Code) | | Constructs a non-delta Codec with the given B, H and S values.
Parameters:
b - the maximum number of bytes that a value can be encoded as[1..5]
Parameters:
h - the radix of the encoding [1..256]
Parameters:
s - whether the encoding represents signed numbers (s=0 isunsigned; s=1 is signed with 1s complement; s=2 is signed with ?) |
| BHSDCodec | | public BHSDCodec(int b, int h, int s, int d)(Code) | | Constructs a Codec with the given B, H, S and D values.
Parameters:
b - the maximum number of bytes that a value can be encoded as[1..5]
Parameters:
h - the radix of the encoding [1..256]
Parameters:
s - whether the encoding represents signed numbers (s=0 isunsigned; s=1 is signed with 1s complement; s=2 is signed with ?)
Parameters:
d - whether this is a delta encoding (d=0 is non-delta; d=1 isdelta) |
| cardinality | | public long cardinality()(Code) | | Returns the cardinality of this codec; that is, the number of distinct
values that it can contain.
the cardinality of this codec |
| encodes | | public boolean encodes(long value)(Code) | | True if this encoding can code the given value
Parameters:
value - the value to check true if the encoding can encode this value |
| getB | | public int getB()(Code) | | the b |
| getH | | public int getH()(Code) | | the h |
| getL | | public int getL()(Code) | | the l |
| isDelta | | public boolean isDelta()(Code) | | Returns true if this codec is a delta codec
true if this codec is a delta codec |
| isSigned | | public boolean isSigned()(Code) | | Returns true if this codec is a signed codec
true if this codec is a signed codec |
| largest | | public long largest()(Code) | | Returns the largest value that this codec can represent.
the largest value that this codec can represent. |
| smallest | | public long smallest()(Code) | | Returns the smallest value that this codec can represent.
the smallest value that this codec can represent. |
| toString | | public String toString()(Code) | | Returns the codec in the form (1,256) or (1,64,1,1). Note that trailing
zero fields are not shown.
