org.jbpm.api.Execution
a runtime path of execution.
State of an execution

The state of an execution is either active or locked. An active execution is either executing or waiting for an external trigger. If an execution is not in {@link #STATE_ACTIVE_ROOT}or {@link #STATE_ACTIVE_CONCURRENT} then it is locked. A locked execution is read only.

When a new execution is created, it is in {@link #STATE_ACTIVE_ROOT}. {@link #STATE_ACTIVE_ROOT Some STATE_* constants} are provided that represent the most commonly used locked states. But the state '...' in the picture indicates that any string can be provided as the state in the lock method.

If an execution is locked, methods that change the execution will throw a {@link JbpmException} and the message will reference the actual locking state.{@link OpenExecution#setVariable(String,Object) updating variables}, {@link OpenExecution#setPriority(int) updating priority} are not considered to change an execution.

Make sure that comparisons between {@link #getState()} and the {@link #STATE_ACTIVE_ROOT STATE_* constants} are done with .equals and not with '==' because if executions are loaded from persistent storage, a new string is created instead of the constants.
