createCondition

default EvaluatorHandle createCondition(ValuesPredicate predicate,
 FieldReference... references)

Registers the provided predicate with the current context (a Knowledge or a RuleSession). The resulting EvaluatorHandle can later be used in the LhsBuilder.where(EvaluatorHandle...) code blocks, shared among other rules (if appropriate), or provided to the EvaluatorsContext.replaceEvaluator(EvaluatorHandle, Evaluator) and EvaluatorsContext.replaceEvaluator(EvaluatorHandle, ValuesPredicate) methods to replace conditions on the fly.

Parameters:

predicate - condition predicate

references - field references

Returns:

evaluator handle

See Also:

• FieldReference
• WorkUnit

createCondition

default EvaluatorHandle createCondition(ValuesPredicate predicate,
 String... references)

Registers the provided predicate with the current context (a Knowledge or a RuleSession). The resulting EvaluatorHandle can later be used in the LhsBuilder.where(EvaluatorHandle...) code blocks, shared among other rules (if appropriate), or provided to the EvaluatorsContext.replaceEvaluator(EvaluatorHandle, Evaluator) and EvaluatorsContext.replaceEvaluator(EvaluatorHandle, ValuesPredicate) methods to replace conditions on the fly.

Parameters:

predicate - condition predicate

references - field references

Returns:

evaluator handle

See Also:

• FieldReference
• WorkUnit

createCondition

default EvaluatorHandle createCondition(Predicate<Object[]> predicate,
 FieldReference... references)

Registers the provided predicate with the current context (a Knowledge or a RuleSession). The resulting EvaluatorHandle can later be used in the LhsBuilder.where(EvaluatorHandle...) code blocks, shared among other rules (if appropriate), or provided to the EvaluatorsContext.replaceEvaluator(EvaluatorHandle, Evaluator) and EvaluatorsContext.replaceEvaluator(EvaluatorHandle, ValuesPredicate) methods to replace conditions on the fly.

Parameters:

predicate - condition predicate

references - field references

Returns:

evaluator handle

See Also:

• FieldReference

createCondition

default EvaluatorHandle createCondition(Predicate<Object[]> predicate,
 String... references)

Registers the provided predicate with the current context (a Knowledge or a RuleSession). The resulting EvaluatorHandle can later be used in the LhsBuilder.where(EvaluatorHandle...) code blocks, shared among other rules (if appropriate), or provided to the EvaluatorsContext.replaceEvaluator(EvaluatorHandle, Evaluator) and EvaluatorsContext.replaceEvaluator(EvaluatorHandle, ValuesPredicate) methods to replace conditions on the fly.

Parameters:

                         throws org.evrete.runtime.compiler.CompilationException

Compiles and registers the provided predicate with the current context (a Knowledge or a RuleSession). The resulting EvaluatorHandle can later be used in the LhsBuilder.where(EvaluatorHandle...) code blocks, shared among other rules (if appropriate), or provided to the EvaluatorsContext.replaceEvaluator(EvaluatorHandle, Evaluator) and EvaluatorsContext.replaceEvaluator(EvaluatorHandle, ValuesPredicate) methods to replace conditions on the fly.
