Method Detail

filter

public boolean filter(FilterContent content)
               throws ContinuousQueryException

Description copied from interface: ContinuousQueryFilter

Checks if the supplied object passes the filter.

Parameters:

content - A representation of the cache entry to be checked

Returns:

true if the object matches the filtering criteria, false otherwise

Throws:

ContinuousQueryException

See Also:

ContinuousQueryFilter.filter(FilterContent)

createString

public String createString()

Description copied from class: AbstractCQFilter

Creates a string representation of the continuous query filter, this method is used by AbstractCQFilter.toString().

The string will be used for identifying and comparing filters, i.e. it will be used in AbstractCQFilter.hashCode() and AbstractCQFilter.equals(Object), so the returned value must be in unique format among all filters in the system.

Specified by:

createString in class AbstractCQFilter<Object,Object,Object,String>

Returns:
