Type Notes — Orkestra

Type notes inspect and convert the runtime Go types of values in the CR. Because Kubernetes stores everything as JSON, field types depend on how the API server serialized them — these notes let you branch on that safely.

Reference

Note	Description
`typeOf`	Return the runtime type name of any value.
`typeMap`	Shorthand predicates — return `true` when the value matches that type.
`typeList`	Shorthand predicates — return `true` when the value matches that type.
`typeString`	Shorthand predicates — return `true` when the value matches that type.
`typeNumber`	Shorthand predicates — return `true` when the value matches that type.
`typeBool`	Shorthand predicates — return `true` when the value matches that type.
`typeNull`	Shorthand predicates — return `true` when the value matches that type.
`isEmpty`	Return `true` when the value is nil, an empty string, an empty slice, or an empty map.
`len`	Return the length of a string, slice, or map.
`toInt`	Convert any value to `int64`.
`toFloat`	Convert any value to `float64`.
`toBool`	Convert a value to `bool`.
`toString`	Convert any value to its string representation.
`toJson`	Convert any value to its JSON representation.
