This software provides a streamlined approach to accessing intricate data structures using delimited keys. It simplifies the process and allows for more efficient access to complex data.
Data::DRef is a versatile Perl module designed to provide a simple yet powerful interface for accessing values within nested Perl data structures. These structures often consist of arrays and hashes that contain a diverse mix of simple scalar values and references to other items in the structure. With Data::DRef, you can easily use delimited key strings to retrieve and set values at specific nodes within the data structure.
While the Data::DRef functions are relatively slower than direct variable access, they offer greater flexibility and convenience for high-level scripting and late-binding behavior. For instance, web-based applications can use DRefs to effortlessly customize user arguments processed by CGI.pm.
Moreover, Data::DRef allows you to take advantage of a suite of utility functions that were previously maintained in a separate Data::Collection module. These functions can perform a wide range of operations across nested data structures, and are equally compatible with arrays, hashes, or objects that provide their key-value interface.
The module's SYNOPSIS provides an overview of Data::DRef's capabilities, including the ability to retrieve and set values with get_value_for_dref and set_value_for_dref, respectively. Moreover, the set_value_for_root_dref function can set a value to a root hash, allowing easy retrieval with get_value_for_root_dref.
Data::DRef also includes other powerful utilities, such as the matching_keys and matching_values functions, which allow you to filter arrays and hashes based on specific criteria. Additionally, the index_by_drefs, unique_index_by_drefs, and ordered_index_by_drefs functions facilitate efficient indexing of nested data structures.
Finally, Data::DRef provides a set of leaf functions, including leaf_drefs, leaf_values, and leaf_drefs_and_values, which make it easy to locate leaf nodes in the data structure and retrieve their values. Overall, Data::DRef is an essential tool for any Perl programmer working with nested data structures, offering a straightforward, versatile interface for data processing and manipulation.
