Method Detail

getDimension

public String getDimension()

getValues

public Set<String> getValues()

getCacheKey

public byte[] getCacheKey()

Specified by:

getCacheKey in interface DimFilter

optimize

public DimFilter optimize()

Specified by:

optimize in interface DimFilter

Returns:

Returns an optimized filter. returning the same filter can be a straightforward default implementation.

toFilter

public Filter toFilter()

Description copied from interface: DimFilter

Returns a Filter that implements this DimFilter. This does not generally involve optimizing the DimFilter, so it does make sense to optimize first and then call toFilter on the resulting DimFilter.

Specified by:

toFilter in interface DimFilter

Returns:

a Filter that implements this DimFilter, or null if this DimFilter is a no-op.

equals

public boolean equals(Object o)
