All Superinterfaces:

NamedWriteable, ToXContent, ToXContentObject, Writeable

All Known Implementing Classes:

AllExpression, AnyExpression, ExceptExpression, FieldExpression

public interface RoleMapperExpression
extends ToXContentObject, NamedWriteable

Implementations of this interface represent an expression over a simple object that resolves to a boolean value. The "simple object" is provided as a ExpressionModel.

Modifier and Type	Method	Description
default Predicate<ExpressionModel>	asPredicate()	Adapt this expression to a standard Predicate

Method Details

match

boolean match(ExpressionModel model)

Determines whether this expression matches against the provided object.

Parameters:

model - the ExpressionModel

asPredicate

default Predicate<ExpressionModel> asPredicate()

Adapt this expression to a standard Predicate

predicate

static Predicate<RoleMapperExpression> predicate(ExpressionModel map)

Creates an inverted predicate that can test whether an expression matches a fixed object. Its purpose is for cases where there is a Stream of expressions, that need to be filtered against a single map.
