## S4 method for signature 'BasicFilter'
show(object)

## S4 method for signature 'src_organism'
supportedFilters(object)

Arguments

object	A BasicFilter or GRangesFilter object
value	Value of the filter. For GRangesFilter value should be a GRanges object.
condition	The condition to be used in filter for genomic extractors, one of "==", "!=", "startsWith", "endsWith", ">", "<", ">=", "<=". For character values "==", "!=", "startsWith" and "endsWith" are allowed, for numeric values (CdsStartFilter, CdsEndFilter, ExonStartFilter, ExonEndFilter, GeneStartFilter, GeneEndFilter, TxStartFilter and TxEndFilter), "==", "!=", ">", ">=", "<" and "<=". Default condition is "==".

Details

All filters except GRangesFilter() takes value(s) from corresponding fields in the data base. For example, AccnumFilter() takes values of accession number(s), which come from field accnum. See keytypes() and keys() for possible values.

GRangesFilter() takes a GRanges object as filter, and returns genomic extractors (genes, transcripts, etc.) that are partially overlapping with the region.

supportedFilters() lists all available filters for src_organism object.

Value

A Filter object showing class, value and condition of the filter
