Field Details

endpoint

protected org.apache.camel.Endpoint endpoint

endpointConsumerBuilder

protected EndpointConsumerBuilder endpointConsumerBuilder

Constructor Details

PollDefinition

public PollDefinition()

PollDefinition

protected PollDefinition(PollDefinition source)

PollDefinition

public PollDefinition(String uri)

PollDefinition

public PollDefinition(org.apache.camel.Endpoint endpoint)

PollDefinition

public PollDefinition(EndpointConsumerBuilder endpointDefinition)

Method Details

getShortName

public String getShortName()

Specified by:

getShortName in interface org.apache.camel.NamedNode

toString

public String toString()

Overrides:

toString in class Object

getVariableReceive

public String getVariableReceive()

setVariableReceive

public void setVariableReceive(String variableReceive)

To use a variable to store the received message body (only body, not headers). This is handy for easy access to the received message body via variables. Important: When using receive variable then the received body is stored only in this variable and not on the current Message.

copyDefinition

public PollDefinition copyDefinition()

Description copied from interface: CopyableDefinition

Makes a copy of this definition.

Specified by:

copyDefinition in interface CopyableDefinition<ProcessorDefinition>

getUri

public String getUri()

setUri

public void setUri(String uri)

Sets the uri of the endpoint to poll from.

Parameters:

uri - the uri of the endpoint

getEndpoint

public org.apache.camel.Endpoint getEndpoint()

Gets the endpoint if an Endpoint instance was set.

This implementation may return null which means you need to use getEndpointUri() to get information about the endpoint.

Returns:

the endpoint instance, or null

setEndpoint

public void setEndpoint(org.apache.camel.Endpoint endpoint)

getTimeout

public String getTimeout()

setTimeout

public void setTimeout(String timeout)

Timeout in millis when polling from the external service.

The timeout has influence about the poll enrich behavior. It basically operations in three different modes:

• negative value - Waits until a message is available and then returns it. Warning that this method could block indefinitely if no messages are available.
• 0 - Attempts to receive a message exchange immediately without waiting and returning null if a message exchange is not available yet.
• positive value - Attempts to receive a message exchange, waiting up to the given timeout to expire if a message is not yet available. Returns null if timed out

The default value is 20000 (20 seconds).

getEndpointConsumerBuilder

public EndpointConsumerBuilder getEndpointConsumerBuilder()

setEndpointConsumerBuilder

public void setEndpointConsumerBuilder(EndpointConsumerBuilder endpointConsumerBuilder)

getEndpointUri

public String getEndpointUri()

Description copied from interface: EndpointRequiredDefinition

Gets the uri of the endpoint used by this definition.

Specified by:

getEndpointUri in interface EndpointRequiredDefinition

getLabel

public String getLabel()

Description copied from class: ProcessorDefinition

Returns a label to describe this node such as the expression if some kind of expression node

Specified by:

getLabel in interface org.apache.camel.NamedNode

Overrides:

getLabel in class ProcessorDefinition<PollDefinition>

clear

protected void clear()
