Method Detail

matches

public static Header matches(String name,
                             String value)

The given name and value patterns may be parameterized:

Header.matches("Accept-Encoding", "{encoding}")
Header.matches("Accept-{type}", "{value}")
...

Parameters:

name - ParameterizedPattern matching the header name.

value - ParameterizedPattern matching the header value.

exists

public static Header exists(String name)

Create a Header condition that matches only against the existence of a header with a name matching the given pattern. The header value is ignored.

The given name pattern may be parameterized:

Header.exists("Accept-Encoding")
Header.exists("Accept-{acceptType}")
Header.exists("{anything}")
...

Parameters:

name - ParameterizedPattern matching the header name.

See Also:

ConfigurationRuleParameterBuilder#where(String) {@link HttpServletRequest#getHeader(String)}

valueExists

public static Header valueExists(String value)

Create a Header condition that matches only against the existence of a header with value matching the given pattern. The header name is ignored.

The given value pattern may be parameterized:

Header.valueExists("application/xml")
Header.valueExists("application/{type}")
Header.valueExists("{anything}")
...

Parameters:

value - ParameterizedPattern matching the header value.
