Method Detail

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.

getDimension

public String getDimension()

getBound

public com.metamx.collections.spatial.search.Bound getBound()

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.

getDimensionRangeSet

public com.google.common.collect.RangeSet<String> getDimensionRangeSet(String dimension)

Description copied from interface: DimFilter

Returns a RangeSet that represents the possible range of the input dimension for this DimFilter.This is applicable to filters that use dimensions such as select, in, bound, and logical filters such as and, or, not. Null represents that the range cannot be determined, and will be returned for filters such as javascript and regex where there's no easy way to determine the filtered range. It is treated the same way as an all range in most cases, however there are some subtle difference at logical filters such as not filter, where complement of all is nothing while complement of null is still null.

Specified by:

getDimensionRangeSet in interface DimFilter

Parameters:

dimension - name of the dimension to get range for

Returns:

a RangeSet that represent the possible range of the input dimension, or null if it is not possible to determine for this DimFilter.
