方法详细资料

setSourceFilesToCompactionCandidate

public void setSourceFilesToCompactionCandidate()

指定者:

setSourceFilesToCompactionCandidate 在类中 AbstractCompactionTask

getSelectedSequenceFiles

public List<TsFileResource> getSelectedSequenceFiles()

getSelectedUnsequenceFiles

public List<TsFileResource> getSelectedUnsequenceFiles()

checkValidAndSetMerging

public boolean checkValidAndSetMerging()

从类复制的说明: AbstractCompactionTask

Check if the compaction task is valid (selected files are not merging, closed and exist). If the task is valid, then set the merging status of selected files to true.

指定者:

checkValidAndSetMerging 在类中 AbstractCompactionTask

返回:

true if the task is valid else false

toString

public String toString()

覆盖:

toString 在类中 Object

resetCompactionCandidateStatusForAllSourceFiles

public void resetCompactionCandidateStatusForAllSourceFiles()

指定者:

resetCompactionCandidateStatusForAllSourceFiles 在类中 AbstractCompactionTask
