public static final class Expr.Comprehension.Builder
extends com.google.protobuf.GeneratedMessageLite.Builder<Expr.Comprehension,Expr.Comprehension.Builder>
implements Expr.ComprehensionOrBuilder
A comprehension expression applied to a list or map.
Comprehensions are not part of the core syntax, but enabled with macros.
A macro matches a specific call signature within a parsed AST and replaces
the call with an alternate AST block. Macro expansion happens at parse
time.
The following macros are supported within CEL:
Aggregate type macros may be applied to all elements in a list or all keys
in a map:
* `all`, `exists`, `exists_one` - test a predicate expression against
the inputs and return `true` if the predicate is satisfied for all,
any, or only one value `list.all(x, x < 10)`.
* `filter` - test a predicate expression against the inputs and return
the subset of elements which satisfy the predicate:
`payments.filter(p, p > 1000)`.
* `map` - apply an expression to all elements in the input and return the
output aggregate type: `[1, 2, 3].map(i, i * i)`.
The `has(m.x)` macro tests whether the property `x` is present in struct
`m`. The semantics of this macro depend on the type of `m`. For proto2
messages `has(m.x)` is defined as 'defined, but not set`. For proto3, the
macro tests whether the property is set to its default. For map and struct
types, the macro tests whether the property `x` is defined on `m`.
Comprehensions for the standard environment macros evaluation can be best
visualized as the following pseudocode:
```
let `accu_var` = `accu_init`
for (let `iter_var` in `iter_range`) {
if (!`loop_condition`) {
break
}
`accu_var` = `loop_step`
}
return `result`
```
Comprehensions for the optional V2 macros which support map-to-map
translation differ slightly from the standard environment macros in that
they expose both the key or index in addition to the value for each list
or map entry:
```
let `accu_var` = `accu_init`
for (let `iter_var`, `iter_var2` in `iter_range`) {
if (!`loop_condition`) {
break
}
`accu_var` = `loop_step`
}
return `result`
```
