ComparisonOperator: Create a Comparison Search Operator

In rPDBapi: A Comprehensive Interface for Accessing the Protein Data Bank

Create a Comparison Search Operator

Description

Constructs a 'ComparisonOperator' object for search operations that perform comparison checks on attribute values. This operator allows for evaluating attributes using comparison operators such as 'equal', 'greater_than', or 'less_than', making it suitable for numerical and date-based searches.

Usage

ComparisonOperator(attribute, value, comparison_type)

Arguments

attribute	The attribute to be compared. This should be the field within the RCSB PDB that you want to evaluate.
value	The value to compare against. This is the reference value for the comparison.
comparison_type	A string specifying the type of comparison (e.g., 'equal', 'greater_than', 'less_than'). Supported comparison types are 'equal', 'not_equal', 'greater_than', 'less_than', etc.

Value

An object of class 'ComparisonOperator' that can be used in search queries to retrieve entries where the attribute meets the specified comparison criteria.

Examples

# Search for entries where an attribute equals a specific value
operator <- ComparisonOperator(attribute = "rcsb_entry_info.resolution_combined",
                                value = 2.0, comparison_type = "EQUAL")
operator
