Properties

[NODE_TYPE]

[NODE_TYPE]: symbol

Optionalanchor

anchor?: string

An optional anchor on this node. Used by alias nodes.

Optionalcomment

comment?: null | string

A comment on or immediately after this

OptionalcommentBefore

commentBefore?: null | string

A comment before this

Optionalflow

flow?: boolean

If true, stringify this and all child nodes using flow rather than block styles.

items

items: T[]

Optionalrange

range?: null | Range

The [start, value-end, node-end] character offsets for the part of the source parsed into this node (undefined if not parsed). The value-end and node-end positions are themselves not included in their respective ranges.

schema

schema: undefined | yaml.Schema

OptionalspaceBefore

spaceBefore?: boolean

A blank line before this node and its commentBefore

OptionalsrcToken

srcToken?: yaml.CST.Token

The CST token that was composed into this node.

Optionaltag

tag?: string

A fully qualified tag, if required

StaticmaxFlowStringSingleLineLength

maxFlowStringSingleLineLength: number

Accessors

StatictagName

  • get tagName(): "tag:yaml.org,2002:seq"

  • Returns "tag:yaml.org,2002:seq"

Methods

add

  • add(value): void

  • Adds a value to the collection.

    Parameters

    • value: T

    Returns void

addIn

  • addIn(path, value): void

  • Adds a value to the collection. For !!map and !!omap the value must be a Pair instance or a { key, value } object, which may not have a key that already exists in the map.

    Parameters

    • path: Iterable<unknown>
    • value: unknown

    Returns void

clone

  • clone(schema?): Collection

  • Create a copy of this collection.

    Parameters

    • Optionalschema: yaml.Schema

      If defined, overwrites the original's schema

    Returns Collection

delete

  • delete(key): boolean

  • Removes a value from the collection.

    key must contain a representation of an integer for this to succeed. It may be wrapped in a Scalar.

    Parameters

    • key: unknown

    Returns boolean

    true if the item was found and removed.

deleteIn

  • deleteIn(path): boolean

  • Removes a value from the collection.

    Parameters

    • path: Iterable<unknown>

    Returns boolean

    true if the item was found and removed.

get

  • get(key, keepScalar): undefined | Scalar<T>

  • Returns item at key, or undefined if not found. By default unwraps scalar values from their surrounding node; to disable set keepScalar to true (collections are always returned intact).

    key must contain a representation of an integer for this to succeed. It may be wrapped in a Scalar.

    Parameters

    • key: unknown
    • keepScalar: true

    Returns undefined | Scalar<T>

  • get(key, keepScalar?): undefined | T

  • Returns item at key, or undefined if not found. By default unwraps scalar values from their surrounding node; to disable set keepScalar to true (collections are always returned intact).

    Parameters

    • key: unknown
    • OptionalkeepScalar: false

    Returns undefined | T

  • get(key, keepScalar?): undefined | T | Scalar<T>

  • Returns item at key, or undefined if not found. By default unwraps scalar values from their surrounding node; to disable set keepScalar to true (collections are always returned intact).

    Parameters

    • key: unknown
    • OptionalkeepScalar: boolean

    Returns undefined | T | Scalar<T>

getIn

  • getIn(path, keepScalar?): unknown

  • Returns item at key, or undefined if not found. By default unwraps scalar values from their surrounding node; to disable set keepScalar to true (collections are always returned intact).

    Parameters

    • path: Iterable<unknown>
    • OptionalkeepScalar: boolean

    Returns unknown

has

  • has(key): boolean

  • Checks if the collection includes a value with the key key.

    key must contain a representation of an integer for this to succeed. It may be wrapped in a Scalar.

    Parameters

    • key: unknown

    Returns boolean

hasAllNullValues

  • hasAllNullValues(allowScalar?): boolean

  • Parameters

    • OptionalallowScalar: boolean

    Returns boolean

hasIn

  • hasIn(path): boolean

  • Checks if the collection includes a value with the key key.

    Parameters

    • path: Iterable<unknown>

    Returns boolean

set

  • set(key, value): void

  • Sets a value in this collection. For !!set, value needs to be a boolean to add/remove the item from the set.

    If key does not contain a representation of an integer, this will throw. It may be wrapped in a Scalar.

    Parameters

    • key: unknown
    • value: T

    Returns void

setIn

  • setIn(path, value): void

  • Sets a value in this collection. For !!set, value needs to be a boolean to add/remove the item from the set.

    Parameters

    • path: Iterable<unknown>
    • value: unknown

    Returns void

toJSON

  • toJSON(_?, ctx?): unknown[]

  • A plain JS representation of this node

    Parameters

    • Optional_: unknown
    • Optionalctx: ToJSContext

    Returns unknown[]

toString

  • toString(ctx?, onComment?, onChompKeep?): string

  • Parameters

    • Optionalctx: StringifyContext
    • OptionalonComment: (() => void)
        • (): void

        • Returns void

    • OptionalonChompKeep: (() => void)
        • (): void

        • Returns void

    Returns string
