Class StringValueMap

Cross-language implementation of a map (dictionary) where all keys and values are strings. The stored values can be converted to different types using variety of accessor methods.

The string map is highly versatile. It can be converted into many formats, stored and sent over the wire.

This class is widely used in Pip.Services as a basis for variety of classes, such as ConfigParams, ConnectionParams, CredentialParams and others.

Example

let value1 = StringValueMap.fromString("key1=1;key2=123.456;key3=2018-01-01");

value1.getAsBoolean("key1");   // Result: true
value1.getAsInteger("key2");   // Result: 123
value1.getAsFloat("key2");     // Result: 123.456
value1.getAsDateTime("key3");  // Result: new Date(2018,0,1)

    Returns StringValueMap

    a newly created AnyValueMap.

Static fromString

  • Parses semicolon-separated key-value pairs and returns them as a StringValueMap.

    fromTuplesArray

    Parameters

    • Rest ...tuples: any[]

      a list of values where odd elements are keys and the following even elements are values

    Returns StringValueMap

    a newly created StringValueMap.

Static fromTuplesArray

  • Creates a new StringValueMap from a list of key-value pairs called tuples. The method is similar to fromTuples but tuples are passed as array instead of parameters.
