This is used when including one file in another; the included file is relativized to the path it's included into in the parent file.
This is used when including one file in another; the included file is
relativized to the path it's included into in the parent file. The point
is that if you include a file at foo.bar
in the parent, and the included
file as a substitution ${a.b.c}
, the included substitution now needs to
be ${foo.bar.a.b.c}
because we resolve substitutions globally only after
parsing everything.

Renders the config value to a string, using the provided options.
Renders the config value to a string, using the provided options.
If the config value has not been resolved (see Config.resolve()]]), it's possible that it can't be rendered as valid HOCON. In that case the rendering should still be useful for debugging but you might not be able to parse it. If the value has been resolved, it will always be parseable.
If the config value has been resolved and the options disable all HOCON-specific features (such as comments), the rendering will be valid JSON. If you enable HOCON-only features such as comments, the rendering will not be valid JSON.

Renders the config value as a HOCON string.
Renders the config value as a HOCON string. This method is primarily intended for debugging, so it tries to add helpful comments and whitespace.
If the config value has not been resolved (see Config.resolve()), it's possible that it can't be rendered as valid HOCON. In that case the rendering should still be useful for debugging but you might not be able to parse it. If the value has been resolved, it will always be parseable.
This method is equivalent to
render(ConfigRenderOptions.defaults())

Returns a new value computed by merging this value with another, with keys in this value "winning" over the other one.
Returns a new value computed by merging this value with another, with keys in this value "winning" over the other one.
This associative operation may be used to combine configurations from multiple sources (such as multiple configuration files).
The semantics of merging are described in the spec for HOCON. Merging typically occurs when either the same object is created twice in the same file, or two config files are both loaded. For example:
foo = { a: 42 } foo = { b: 43 }
Here, the two objects are merged as if you had written:
foo = { a: 42, b: 43 }
Only ConfigObject
and Config
instances do anything in
this method (they need to merge the fallback keys into themselves). All
other values just return the original value, since they automatically
override any fallback. This means that objects do not merge "across"
non-objects; if you write
object.withFallback(nonObject).withFallback(otherObject)
,
then otherObject
will simply be ignored. This is an
intentional part of how merging works, because non-objects such as
strings and integers replace (rather than merging with) any prior value:
foo = { a: 42 } foo = 10
Here, the number 10 "wins" and the value of foo
would be
simply 10. Again, for details see the spec.
