Method Detail

parseStringDelimited

public static String parseStringDelimited(com.google.protobuf.Struct struct,
                                          String path,
                                          String delimiter)

Parses a node in the Struct into a delimited string. This is convenient in case the node itself, or one of its parents, is a list with multiple entries.

Parameters:

struct - The Struct to parse.

path - The path of node to parse, separated by period ("."). Ex: "parent.child.grandChild"

delimiter - The delimiter to use in the resulting String

Returns:

A delimited string representation of parsed Struct

parseStringList

public static List<String> parseStringList(com.google.protobuf.Struct struct,
                                           List<String> path)

Parses a node in the Struct into a List<String>. This is convenient in case the node itself, or one of its parents, is a list.

Parameters:

struct - The Struct to parse.

path - The path of node to parse, each item in the list is a path component.

Returns:

A list of the data matching the path. If no match, then an empty list is returned.

parseStringList

public static List<String> parseStringList(com.google.protobuf.Value value,
                                           List<String> path)

Parses a node in the Value into a List<String>. This is convenient in case the node itself, or one of its parents, is a list.

Parameters:

value - The Value to parse

path - The path of node to parse, each item in the list is a path component.

Returns:

A list of the data matching the path. If no match, then an empty list is returned.
