How to get list of Workflows/IWorkflowInfo of IProjectArea

I found internal API
com.ibm.team.workitem.common.internal.workflow.WorkflowManager

is there some public analog?

There are two methods that may help you:

IWorkItemCommon#findCombinedWorkflowInfos(IProjectAreaHandle
projectArea, IProgressMonitor monitor)

and

IWorkItemCommon#findWorkflowInfo(IWorkItem workItem, IProgressMonitor
monitor)

I need some API to get IWorkflowInfo by workItem type category.

I found it in WorkflowManager, but it is internal:

public String getWorkflowIdForCategory(IProjectAreaHandle projectArea, String category, boolean shortOp, IProgressMonitor monitor)
and
public IWorkflowInfo getWorkflowInfo(IProjectAreaHandle projectArea, String workflowId, boolean shortOp, IProgressMonitor monitor)

I need some API to get IWorkflowInfo by workItem type category.

I found it in WorkflowManager, but it is internal:

public String getWorkflowIdForCategory(IProjectAreaHandle projectArea,
String category, boolean shortOp, IProgressMonitor monitor)
and
public IWorkflowInfo getWorkflowInfo(IProjectAreaHandle projectArea,
String workflowId, boolean shortOp, IProgressMonitor monitor)

To avoid the internal API, you could create a work item in memory, set
its type to one one of the type category's types and use the public

findWorkflowInfo(workItem, monitor);
