Method Summary

Modifier and Type	Method	Description
java.lang.Object	advanceEvaluation(UnknownContext context)	Advance evaluation based on the current unknown context.
java.lang.Object	eval(com.google.protobuf.Message message)	Evaluate the expression using message fields as the source of input variables.
java.lang.Object	trace(com.google.protobuf.Message message, CelEvaluationListener listener)	Trace evaluates a compiled program using message fields as the source of input variables.
java.lang.Object	trace(CelEvaluationListener listener)	Trace evaluates a compiled program without any variables and invokes the listener as evaluation progresses through the AST.

java.lang.Object	trace(CelVariableResolver resolver, CelFunctionResolver lateBoundFunctionResolver, CelEvaluationListener listener)	Trace evaluates a compiled program using a custom variable resolver and late-bound functions lateBoundFunctionResolver.
java.lang.Object	trace(PartialVars partialVars, CelEvaluationListener listener)	Trace evaluates a compiled program using partialVars as the source of input variables and unknown attribute patterns.
java.lang.Object	trace(java.util.Map<java.lang.String,?> mapValue, CelEvaluationListener listener)	Trace evaluates a compiled program using a mapValue as the source of input variables.
java.lang.Object	trace(java.util.Map<java.lang.String,?> mapValue, CelFunctionResolver lateBoundFunctionResolver, CelEvaluationListener listener)	Trace evaluates a compiled program using a mapValue as the source of input variables and late-bound functions lateBoundFunctionResolver.

Method Detail

eval

java.lang.Object eval(com.google.protobuf.Message message)
               throws CelEvaluationException

Evaluate the expression using message fields as the source of input variables.

Throws:

CelEvaluationException

trace

java.lang.Object trace(CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program without any variables and invokes the listener as evaluation progresses through the AST.

Throws:

CelEvaluationException

trace

java.lang.Object trace(java.util.Map<java.lang.String,?> mapValue,
                       CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program using a mapValue as the source of input variables. The listener is invoked as evaluation progresses through the AST.

Throws:

CelEvaluationException

trace

java.lang.Object trace(com.google.protobuf.Message message,
                       CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program using message fields as the source of input variables. The listener is invoked as evaluation progresses through the AST.

Throws:

CelEvaluationException

trace

java.lang.Object trace(CelVariableResolver resolver,
                       CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program using a custom variable resolver. The listener is invoked as evaluation progresses through the AST.

Throws:

CelEvaluationException

trace

java.lang.Object trace(CelVariableResolver resolver,
                       CelFunctionResolver lateBoundFunctionResolver,
                       CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program using a custom variable resolver and late-bound functions lateBoundFunctionResolver. The listener is invoked as evaluation progresses through the AST.

Throws:

CelEvaluationException

trace

java.lang.Object trace(java.util.Map<java.lang.String,?> mapValue,
                       CelFunctionResolver lateBoundFunctionResolver,
                       CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program using a mapValue as the source of input variables and late-bound functions lateBoundFunctionResolver. The listener is invoked as evaluation progresses through the AST.

Throws:

CelEvaluationException

trace

java.lang.Object trace(PartialVars partialVars,
                       CelEvaluationListener listener)
                throws CelEvaluationException

Trace evaluates a compiled program using partialVars as the source of input variables and unknown attribute patterns. The listener is invoked as evaluation progresses through the AST.

Throws:

CelEvaluationException

advanceEvaluation

java.lang.Object advanceEvaluation(UnknownContext context)
                            throws CelEvaluationException

Advance evaluation based on the current unknown context.

This represents one round of incremental evaluation and may return a final result or a CelUnknownSet.

If no unknowns are declared in the context or UnknownTracking is disabled, this is equivalent to eval.

Throws:

CelEvaluationException
