All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`build(BuildContext context, BuildUtils utils, org.drools.base.rule.RuleConditionElement rce)`	Builds and attach if needed the given RuleConditionalElement
`boolean`	`requiresLeftActivation(BuildUtils utils, org.drools.base.rule.RuleConditionElement rce)`	A boolean function that indicates if the builder requires a previous left (tuple) activation in order to corretly build the given component.

  - build
```
void build(BuildContext context,
           BuildUtils utils,
           org.drools.base.rule.RuleConditionElement rce)
```
    Builds and attach if needed the given RuleConditionalElement
    
    Parameters:
    
    context - current build context
    
    rce -
  - requiresLeftActivation
```
boolean requiresLeftActivation(BuildUtils utils,
                               org.drools.base.rule.RuleConditionElement rce)
```
    A boolean function that indicates if the builder requires a previous left (tuple) activation in order to corretly build the given component. In other words, if it returns true and no previous TupleSource is already created, an InitialFact pattern must be added with appropriate left input adapter for the network to be correctly built. For instance, NOT / EXISTS / ACCUMULATE are examples of builders that must return true for this method, while PATTERN must return false.
    
    Parameters:
    
    rce - the element to be built
    
    Returns:
    
    true if a tuple source is required, false otherwise.
