Constructor Detail

MediaRange

public MediaRange(String exp)

Constructs a MediaRange from a String expression.

Parameters:

exp - The String to construct the MediaRange from. The string is expected to be on the form ( "*/*" | ( type "/" "*" ) | ( type "/" subtype ) ) *( ";" parameter )
as specified by RFC 2616, section 14.1.

Examples:

• text/html;q=0.8
• text/html
• text/html;level=3
• text/html;level=3;q=0.7
• text/*
• */*

Note that if the supertype component is wildcard (*), then the subtype component must also be wildcard.

The quality factor parameter must be between 0 and 1, inclusive (see RFC 2616 section 3.9). If the expression does not contain a q parameter, the MediaRange is given a default quality factor of 1.

Throws:

IllegalArgumentException - if exp can not be parsed to a valid media range

NullPointerException - if exp is null
