OverlappingFieldsCanBeMerged::collectConflictsBetween │ protected │ WC 1.0

Collect all Conflicts between two collections of fields. This is similar to, but different from the collectConflictsWithin function above. This check assumes that collectConflictsWithin has already been called on each provided collection of fields. This is true because this validator traverses each individual selection set.

Method of the class: OverlappingFieldsCanBeMerged{}

No Hooks.

Returns

null. Nothing (null).

Usage

// protected - for code of main (parent) or child class
$result = $this->collectConflictsBetween( $context, $conflicts, $parentFieldsAreMutuallyExclusive, $fieldMap1, $fieldMap2 ): void;
$context(QueryValidationContext) (required)
.
$conflicts(array) (required)
.
$parentFieldsAreMutuallyExclusive(true|false) (required)
.
$fieldMap1(array) (required)
.
$fieldMap2(array) (required)
.
