Method Summary

Modifier and Type	Method and Description
static YamlMapping	asMapping(YamlNode node) Takes a generic YamlNode instance and returns it casted to YamlMapping if the type of the node is a descendant of YamlMapping.
static YamlScalar	asScalar(YamlNode node) Takes a generic YamlNode instance and returns it casted to YamlScalar if the type of the node is a descendant of YamlScalar.
static YamlSequence	asSequence(YamlNode node) Takes a generic YamlNode instance and returns it casted to YamlSequence if the type of the node is a descendant of YamlSequence.
static <T> T	asType(YamlNode node, Class<T> type) Takes a generic YamlNode instance and returns it casted to the provided type if the node is an instance of that type.
static void	ensureRunningOnJava8OrHigher() Checks if the runtime environment is Java8 or higher.

Method Detail

asMapping

public static YamlMapping asMapping(YamlNode node)

Takes a generic YamlNode instance and returns it casted to YamlMapping if the type of the node is a descendant of YamlMapping.

Parameters:

node - The generic node to cast

Returns:

the casted mapping

Throws:

YamlException - if the provided node is not a mapping

asSequence

public static YamlSequence asSequence(YamlNode node)

Takes a generic YamlNode instance and returns it casted to YamlSequence if the type of the node is a descendant of YamlSequence.

Parameters:

node - The generic node to cast

Returns:

the casted sequence

Throws:

YamlException - if the provided node is not a sequence

asScalar

public static YamlScalar asScalar(YamlNode node)

Takes a generic YamlNode instance and returns it casted to YamlScalar if the type of the node is a descendant of YamlScalar.

Parameters:

node - The generic node to cast

Returns:

the casted scalar

Throws:

YamlException - if the provided node is not a scalar

asType

public static <T> T asType(YamlNode node,
                           Class<T> type)

Takes a generic YamlNode instance and returns it casted to the provided type if the node is an instance of that type.

Parameters:

node - The generic node to cast

Returns:

the casted node

Throws:

YamlException - if the provided node is not the expected type

ensureRunningOnJava8OrHigher

public static void ensureRunningOnJava8OrHigher()

Checks if the runtime environment is Java8 or higher. If the runtime is an older version the check throws UnsupportedOperationException.

Throws:

UnsupportedOperationException - If the runtime environment is not Java8 or higher
