Constructor Details

ExtractionDimFilter

public ExtractionDimFilter(String dimension,
 String value,
 ExtractionFn extractionFn,
 @Deprecated
 ExtractionFn dimExtractionFn)

Deprecated.

Method Details

getDimension

public String getDimension()

Deprecated.

getValue

public String getValue()

Deprecated.

getExtractionFn

public ExtractionFn getExtractionFn()

Deprecated.

getCacheKey

public byte[] getCacheKey()

Deprecated.

Description copied from interface: Cacheable

Get a byte array used as a cache key.

Specified by:

getCacheKey in interface Cacheable

Returns:

bytes to be used as cache key - or null if this object should not be cached.

optimize

public DimFilter optimize(boolean mayIncludeUnknown)

Deprecated.

Description copied from interface: DimFilter

Returns an optimized version of this filter.

Specified by:

optimize in interface DimFilter

Overrides:

optimize in class AbstractOptimizableDimFilter

Parameters:

mayIncludeUnknown - whether the optimized filter may need to operate in "includeUnknown" mode.

toFilter

public Filter toFilter()

Deprecated.

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)

Deprecated.

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.

getRequiredColumns

public Set<String> getRequiredColumns()

Deprecated.

Specified by:

getRequiredColumns in interface DimFilter

Returns:

a HashSet that represents all columns' name which the DimFilter required to do filter.

toString

public String toString()

Deprecated.

Overrides:

toString in class Object
