| Constructor Summary | |
| public | SequenceMapping()
C'tor: This will generate an instance that generated IDxxxxx
symbols. | | public | SequenceMapping(String prefix)
C'tor: Instances from this contructor will generate ${prefix}xxxxx.
Please note that multiple instances of this class with the same
prefix will produce the same sequences!
Parameters:
prefix - is a prefix to the generated sequence. |
| Method Summary | |
| public String | forward(String id)
Creates and caches a unique id for a given short identifier.
Parameters:
id - is the external identifier which needs to be forward mapped. | | public String | get(String shortid)
Obtains existing mapping without producing a new one. |
| SequenceMapping | | public SequenceMapping()(Code) | | C'tor: This will generate an instance that generated IDxxxxx
symbols. Please note that multiple instances of this class will
produce the same sequences!
|
| SequenceMapping | | public SequenceMapping(String prefix)(Code) | | C'tor: Instances from this contructor will generate ${prefix}xxxxx.
Please note that multiple instances of this class with the same
prefix will produce the same sequences!
Parameters:
prefix - is a prefix to the generated sequence. |
| forward | | public String forward(String id)(Code) | | Creates and caches a unique id for a given short identifier.
Parameters:
id - is the external identifier which needs to be forward mapped. a sequence-generated identifier to use instead. |
| get | | public String get(String shortid)(Code) | | Obtains existing mapping without producing a new one. May return
null if no mapping exists.
Parameters:
shortid - is the external identifier to check fwd mapping for null, if no such mapping exists. |
