public static final HttpRequestHeader CONTENT_LENGTH

X_HOPS

public static final HttpRequestHeader X_HOPS

Method Detail

values

public static HttpRequestHeader[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (HttpRequestHeader c : HttpRequestHeader.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static HttpRequestHeader valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getName

public String getName()

containsHeader

public static boolean containsHeader(io.vertx.core.MultiMap headers,
                                     HttpRequestHeader httpRequestHeader)

getInteger

public static Integer getInteger(io.vertx.core.MultiMap headers,
                                 HttpRequestHeader httpRequestHeader)

Get the value of the provided HttpRequestHeader as Integer.

Returns null in the following cases:

• headers are null
• headers does not contain httpRequestHeader
• httpRequestHeader is no parsable Integer i.e. empty string, non-digit characters, numbers to bigger than Integer allows

Parameters:

headers - the http request headers

httpRequestHeader - the http request header to get the value from

Returns:

an Integer representing the value of the httpRequestHeader or null

getInteger

public static Integer getInteger(io.vertx.core.MultiMap headers,
                                 HttpRequestHeader httpRequestHeader,
                                 Integer defaultValue)

Get the value of the provided HttpRequestHeader or a default value as Integer.

Returns the default value in the following cases:

• headers are null
• headers does not contain httpRequestHeader
• httpRequestHeader is no parsable Integer i.e. empty string, non-digit characters, numbers to bigger than Integer allows

Parameters:

headers - the http request headers

httpRequestHeader - the http request header to get the value from

defaultValue - the default value to return when no value from httpRequestHeader is extractable

Returns:

an Integer representing the value of the httpRequestHeader or the default value

getString

public static String getString(io.vertx.core.MultiMap headers,
                               HttpRequestHeader httpRequestHeader)

Get the value of the provided HttpRequestHeader as String.

Returns null in the following cases:

• headers are null

Parameters:

headers - the http request headers

httpRequestHeader - the http request header to get the value from

Returns:

a String representing the value of the httpRequestHeader or null
