Constructor Detail

JobQueue.DuplicateFinder

public JobQueue.DuplicateFinder()

Method Detail

doesCompareWork

public boolean doesCompareWork()

See if this class can be legitimately compared against another of the same type.

Specified by:

doesCompareWork in interface ILimitChecker

Returns:

true if comparisons will ever return "true".

duplicate

public ILimitChecker duplicate()

Create a duplicate of this class instance. All current state should be preserved. NOTE: Since doesCompareWork() returns false, queries using this limit checker cannot be cached, and therefore duplicate() is never called from the query executor.

Specified by:

duplicate in interface ILimitChecker

Returns:

the duplicate.

hashCode

public int hashCode()

Find the hashcode for this class. This will only ever be used if doesCompareWork() returns true.

Specified by:

hashCode in interface ILimitChecker

Overrides:

hashCode in class java.lang.Object

Returns:

the hashcode.

equals

public boolean equals(java.lang.Object object)

Compare two objects and see if equal. This will only ever be used if doesCompareWork() returns true.

Specified by:

equals in interface ILimitChecker

Overrides:

equals in class java.lang.Object

Parameters:

object - is the object to compare against.

Returns:

true if equal.

checkInclude

public boolean checkInclude(IResultRow row)
                     throws ManifoldCFException

See if a result row should be included in the final result set.

Specified by:

checkInclude in interface ILimitChecker

Parameters:

row - is the result row to check.

Returns:

true if it should be included, false otherwise.

Throws:

ManifoldCFException

checkContinue

public boolean checkContinue()
                      throws ManifoldCFException

See if we should examine another row.

Specified by:

checkContinue in interface ILimitChecker

Returns:

true if we need to keep going, or false if we are done.

Throws:

ManifoldCFException
