Detailed Description

Provides an interface to specify a path to a key in a document ID that you can then call a function on to get the value at the specified key as a specific type.

You obtain a DocumentIdPath by subscripting a DocumentId and you can then further subscript a DocumentIdPath to further specify the key of the document ID that you want to get the value of.

Member Function Documentation

get_bool_value()

bool ditto::DocumentIdPath::get_bool_value

(

)

Returns the value at the previously specified key in the document ID as a bool. If the key was invalid a default value of false will be returned.

Returns

The value at the path specified by the document ID subscripting as a bool. The return value will be false if the key was invalid or the value was not a boolean type.

get_double_value()

double ditto::DocumentIdPath::get_double_value

(

)

Returns the value at the previously specified key in the document ID as a double. If the key was invalid a default value of 0 will be returned.

Returns

The value at the path specified by the document ID subscripting as a double. The return value will be 0 if the key was invalid or the value was not a numeric type.

get_float_value()

float ditto::DocumentIdPath::get_float_value

(

)

Returns the value at the previously specified key in the document ID as a float. If the key was invalid a default value of 0 will be returned.

Returns

The value at the path specified by the document ID subscripting as a float. The return value will be 0 if the key was invalid or the value was not a numeric type.

get_int_value()

int ditto::DocumentIdPath::get_int_value

(

)

Returns the value at the previously specified key in the document ID as an int. If the key was invalid a default value of 0 will be returned.

Returns

The value at the path specified by the document ID subscripting as an int. The return value will be 0 if the key was invalid or the value was not a numeric type.

get_json()

json ditto::DocumentIdPath::get_json

(

)

Returns the value at the previously specified key in the document ID as a nlohmann::json object. If the key was invalid the return value will be a nullptr.

Returns

The value at the path specified by the document ID subscripting as a nlohmann::json object. The return value will be a nullptr if the key was invalid.

get_string_value()

std::string ditto::DocumentIdPath::get_string_value

(

)

Returns the value at the previously specified key in the document ID as a std::string. If the key was invalid a default value of an empty string will be returned.

Returns

The value at the path specified by the document ID subscripting as a std::string. The return value will be an empty string if the key was invalid or the value was not a string.
