Function: isPermissionInSet()

isPermissionInSet(permissionSet, permission): boolean

Defined in: src/base/authorization.ts:125

Tests whether a permission hash-set contains the specified permission or expression.

Parameters

permissionSet

Dictionary of granted permissions (key → true). null/undefined yields false.

permission

string

Permission key or expression with &/| operators. null returns false.

Returns

boolean

true if the permission is implied by the set, otherwise false.

Remarks

Handles logical operators: "A&B" requires all listed permissions, "A|B" requires at least one. & binds tighter than |, so "A&B|C" is (A AND B) OR C. An exact key match is checked first before parsing operators.

Examples

Authorization.isPermissionInSet({ "A": true, "B": true }, "A&B"); // true

Authorization.isPermissionInSet({ "A": true }, "A|C"); // true

Authorization.isPermissionInSet({ "A": true }, "A&B"); // false
