public CamelMessage(java.lang.Object body,
                    scala.collection.immutable.Map<java.lang.String,java.lang.Object> headers)

CamelMessage

public CamelMessage(java.lang.Object body,
                    java.util.Map<java.lang.String,java.lang.Object> headers)

Method Detail

MessageExchangeId

public static java.lang.String MessageExchangeId()

CamelMessage header to correlate request with response messages. Applications that send messages to a Producer actor may want to set this header on the request message so that it can be correlated with an asynchronous response. Messages send to Consumer actors have this header already set.

Returns:

(undocumented)

canonicalize

public static CamelMessage canonicalize(java.lang.Object msg)

Creates a canonical form of the given message msg. If msg of type CamelMessage then msg is returned, otherwise msg is set as body of a newly created CamelMessage object.

Parameters:

msg - (undocumented)

Returns:

(undocumented)

from

public static CamelMessage from(org.apache.camel.Message camelMessage,
                                scala.collection.immutable.Map<java.lang.String,java.lang.Object> headers)

Creates a new CamelMessage object from the Camel message.

Parameters:

headers - additional headers to set on the created CamelMessage in addition to those in the Camel message.

camelMessage - (undocumented)

Returns:

(undocumented)

copyContent

public static void copyContent(CamelMessage from,
                               org.apache.camel.Message to)

INTERNAL API copies the content of this CamelMessage to an Apache Camel Message.

Parameters:

from - (undocumented)

to - (undocumented)

body

public java.lang.Object body()

headers

public scala.collection.immutable.Map<java.lang.String,java.lang.Object> headers()

toString

headers

public scala.collection.immutable.Map<java.lang.String,java.lang.Object> headers(scala.collection.immutable.Set<java.lang.String> names)

Returns those headers from this message whose name is contained in names.

Parameters:

names - (undocumented)

Returns:

(undocumented)

getHeaders

public java.util.Map<java.lang.String,java.lang.Object> getHeaders(java.util.Set<java.lang.String> names)

Java API: Returns those headers from this message whose name is contained in names. The returned headers map is backed up by an immutable headers map. Any attempt to modify the returned map will throw an exception.

Parameters:

names - (undocumented)

Returns:

(undocumented)

getHeaders

public java.util.Map<java.lang.String,java.lang.Object> getHeaders()

Java API: Returns all headers from this message. The returned headers map is backed up by this message's immutable headers map. Any attempt to modify the returned map will throw an exception.

Returns:

(undocumented)

withHeaders

public <A> CamelMessage withHeaders(java.util.Map<java.lang.String,A> headers)

Java API: Creates a new CamelMessage with given headers. A copy of the headers map is made.
