- The current working memoryextractor
- The extractor used to get the field value from the objecthandle1
- The source object to evaluate, i.e., the factfieldValue
- The actual value to compare to, i.e., the constant value.public boolean evaluateCachedRight(InternalWorkingMemory workingMemory, VariableRestriction.VariableContextEntry context, InternalFactHandle left)
Evaluator
workingMemory
- The current working memorycontext
- The previously cached context, including the right value
and the extractor for the left value.left
- The left object, from where to extract the bound variable.
In the above example, that is the "$someName" variable value.public boolean evaluateCachedLeft(InternalWorkingMemory workingMemory, VariableRestriction.VariableContextEntry context, InternalFactHandle right)

and the extractor for the right value.right
- The right object, from where to extract the value. In the
above example, that is the "Person" instance from where to
extract the "name" attribute.public boolean evaluate(InternalWorkingMemory workingMemory, InternalReadAccessor extractor1, InternalFactHandle handle1, InternalReadAccessor extractor2, InternalFactHandle handle2)

- The current working memoryextractor1
- The extractor to read the left value. In the above example,

extracted.extractor2
- The extractor to read the right value. In the above example,
