MIMEParams class

  • Reference
Package:
powerbi-client

The MIMEParams API provides read and write access to the parameters of a MIMEType.

Methods

delete(string)

Remove all name-value pairs whose name is name.
entries()

Returns an iterator over each of the name-value pairs in the parameters. Each item of the iterator is a JavaScript Array. The first item of the array is the name, the second item of the array is the value.
get(string)

Returns the value of the first name-value pair whose name is name. If there are no such pairs, null is returned.
has(string)

Returns true if there is at least one name-value pair whose name is name.
keys()

Returns an iterator over the names of each name-value pair.

import { MIMEType } from 'node:util';

const { params } = new MIMEType('text/plain;foo=0;bar=1');
for (const name of params.keys()) {
  console.log(name);
}
// Prints:
//   foo
//   bar
set(string, string)

Sets the value in the MIMEParams object associated with name to value. If there are any pre-existing name-value pairs whose names are name, set the first such pair's value to value.

import { MIMEType } from 'node:util';

const { params } = new MIMEType('text/plain;foo=0;bar=1');
params.set('foo', 'def');
params.set('baz', 'xyz');
console.log(params.toString());
// Prints: foo=def;bar=1;baz=xyz
values()

Returns an iterator over the values of each name-value pair.
[iterator]()

Returns an iterator over each of the name-value pairs in the parameters.

Method Details

delete(string)

Remove all name-value pairs whose name is name.

function delete(name: string)

Parameters

name

string

entries()

Returns an iterator over each of the name-value pairs in the parameters. Each item of the iterator is a JavaScript Array. The first item of the array is the name, the second item of the array is the value.

function entries(): Iterator<[name, value], any, any>

Returns

Iterator<[name, value], any, any>

get(string)

Returns the value of the first name-value pair whose name is name. If there are no such pairs, null is returned.

function get(name: string): null | string

Parameters

name

string

Returns

null | string

or null if there is no name-value pair with the given name.

has(string)

Returns true if there is at least one name-value pair whose name is name.

function has(name: string): boolean

Parameters

name

string

Returns

boolean

keys()

Returns an iterator over the names of each name-value pair.

import { MIMEType } from 'node:util';

const { params } = new MIMEType('text/plain;foo=0;bar=1');
for (const name of params.keys()) {
  console.log(name);
}
// Prints:
//   foo
//   bar

function keys(): Iterator<string, any, any>

Returns

Iterator<string, any, any>

set(string, string)

Sets the value in the MIMEParams object associated with name to value. If there are any pre-existing name-value pairs whose names are name, set the first such pair's value to value.

import { MIMEType } from 'node:util';

const { params } = new MIMEType('text/plain;foo=0;bar=1');
params.set('foo', 'def');
params.set('baz', 'xyz');
console.log(params.toString());
// Prints: foo=def;bar=1;baz=xyz

function set(name: string, value: string)

Parameters

name

string

value

string

values()

Returns an iterator over the values of each name-value pair.

function values(): Iterator<string, any, any>

Returns

Iterator<string, any, any>

[iterator]()

Returns an iterator over each of the name-value pairs in the parameters.

function [iterator](): Iterator<[name, value], any, any>

Returns

Iterator<[name, value], any, any>
