BMC Helix Business Workflows connector documentation reference

This topic was edited by a BMC Contributor and has not been approved.  More information.

This is the main class of an extension, is the entry point from which configurations, connection providers, operations and sources are going to be declared.

Configurations


Config

Default configuration

Parameters

Name

Type

Description

Default Value

Required

Name

String

The name for this configuration. Connectors reference the configuration with this name.


x 

Connection

Connection

The connection types that can be provided to this configuration.


x 

Expiration Policy

Expiration Policy

Configures the minimum amount of time that a dynamic configuration instance can remain idle before the runtime considers it eligible for expiration. This does not mean that the platform will expire the instance at the exact moment that it becomes eligible. The runtime will actually purge the instances when it sees it fit.




Connection Types

Connection

This class (as it's name implies) provides connection instances and the funcionality to disconnect and validate those connections.
All connection related parameters (values required in order to create a connection) must be declared in the connection providers.
This particular example is a PoolingConnectionProvider which declares that connections resolved by this provider will be pooled and reused. There are other implementations like CachedConnectionProvider which lazily creates and caches connections or simply ConnectionProvider if you want a new connection each time something requires one.

Repeatable In Memory Stream

Field

Type

Description

Default Value

Required

Initial Buffer Size

Number

This is the amount of memory that will be allocated in order to consume the stream and provide random access to it. If the stream contains more data than can be fit into this buffer, then it will be expanded by according to the bufferSizeIncrement attribute, with an upper limit of maxInMemorySize.



Buffer Size Increment

Number

This is by how much will be buffer size by expanded if it exceeds its initial size. Setting a value of zero or lower will mean that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error will be raised when the buffer gets full.



Max Buffer Size

Number

This is the maximum amount of memory that will be used. If more than that is used then a STREAM_MAXIMUM_SIZE_EXCEEDED error will be raised. A value lower or equal to zero means no limit.
