Class FilterProjectionExpression

java.lang.Object

software.amazon.smithy.jmespath.JmespathExpression

software.amazon.smithy.jmespath.ast.BinaryExpression

software.amazon.smithy.jmespath.ast.FilterProjectionExpression

public final class FilterProjectionExpression
extends BinaryExpression

A projection that filters values using a comparison.

A filter projection executes the left AST expression, expects it to return an array of values, passes each result of the left expression to a ComparatorExpression, and yields any value from the comparison expression that returns true to the right AST expression.

Note: while this expression does have a comparator expression, it is still considered a binary expression because it has a left hand side and a right hand side.
