public class FormFields
extends AbstractHttpFields<FormFields>

The FormFields represent the URL's Query-String by the notation originally used by the GET request of the ancient web forms (see "https://en.wikipedia.org/wiki/Query_string#Web_forms"). Therefore the name FormFields, as them web forms provided fields with values (see "https://en.wikipedia.org/wiki/Form_(HTML)")

Constructor Details

FormFields

public FormFields()

Instantiates a new form fields impl.

FormFields

public FormFields(Map<String,List<String>> aHttpFields)

Initializes the instance with the fields provided by the given Map.

Parameters:

aHttpFields - The Map from which to get the keys and values for initializing this instance.

FormFields

public FormFields(String aHttpFormFields)

Initializes the instance with the fields provided by the given HTTP Form-Fields (HTTP Query-String).

Parameters:

aHttpFormFields - The String from which to parse the keys and values for initializing this instance.

Method Details

fromUrlQueryString

public void fromUrlQueryString(String aQueryString)

Processes the HTTP Query-String and retrieves the therein defined Form-Fields and adds them to the FormFields instance.

Parameters:

aQueryString - The HTTP Query-String from which to extract the form being added to the FormFields instance.

fromBodyFormFields

public void fromBodyFormFields(String aHttpFormFields)

Processes the HTTP Form-Fields body String and retrieves the therein defined Form-Fields and adds them to the FormFields instance.

Parameters:

aHttpFormFields - The HTTP Form-Fields String from which to extract the form being added to the FormFields instance.

toUrlQueryString

public String toUrlQueryString()

Produces an HTTP Query-String form the herein contain HTTP query fields.

Returns:

The HTTP Query-String representation of this FormFields instance or null if this instance is empty.

toBodyFormFields

public String toBodyFormFields()

Produces an HTTP Form-Fields body String form the herein contain HTTP query fields.

Returns:

The HTTP Form-Fields String representation of this FormFields instance or null if this instance is empty.

toContentLength

public int toContentLength()

Calculates the length (number of characters) of the FormFields when used for a HTTP-Body as of toBodyFormFields().

Returns:

The length of the HTTP-Body representation of the content of these FormFields.

fromUrl

public void fromUrl(String aUrl)

Extracts the HTTP Query-String from the provided URL by identifying the first question mark ("?") and retrieves the therein defined Form-Fields and adds them to the FormFields instance.

Parameters:

aUrl - The URL from which to extract the HTTP Query-String which's Form-Fields are to be added to the FormFields instance.
