Member Enumeration Documentation

◆ type

enum hocon::config_value::type

stronginherited

The type of a configuration value (following the JSON type schema).

Definition at line 56 of file config_value.hpp.

Member Function Documentation

◆ at_key()

shared_config hocon::config_value::at_key ( std::string const & key ) const

inherited

Places the value inside a config at the given key.

◆ at_path()

shared_config hocon::config_value::at_path ( std::string const & path_expression ) const

inherited

Places the value inside a config at the given path.

◆ origin()

virtual shared_origin const& hocon::config_value::origin ( ) const

virtualinherited

The origin of the value (file, line number, etc.), for debugging and error messages.

Returns: where the value came from

◆ relativized()

virtual shared_value hocon::config_value::relativized ( std::string prefix ) const

inlinevirtualinherited

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.

Parameters

prefix

Returns: value relativized to the given path or the same value if nothing to do

Reimplemented in hocon::config_concatenation, and hocon::simple_config_list.

Definition at line 181 of file config_value.hpp.

◆ render() [1/2]

virtual std::string hocon::config_value::render ( ) const

virtualinherited

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(config_render_options())

.

Returns: the rendered value

◆ render() [2/2]

virtual std::string hocon::config_value::render ( config_render_options options ) const

virtualinherited

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.

Parameters

options the rendering options

Returns: the rendered value

◆ to_fallback_value()

shared_value hocon::config_value::to_fallback_value ( ) const

overrideprotectedvirtualinherited

Converts a config to its root object and a config_value to itself.

Originally in the MergeableValue interface, squashing to ease C++ public API separation

Implements hocon::config_mergeable.

◆ value_type()

config_value::type hocon::config_boolean::value_type ( ) const

overridevirtual

The type of the value; matches the JSON type schema.

Returns: value's type

Implements hocon::config_value.

◆ value_type_name()

char const* hocon::config_value::value_type_name ( ) const

inlineinherited

The printable name of the value type.

Returns: value's type's name

Definition at line 92 of file config_value.hpp.

◆ with_fallback()

std::shared_ptr<const config_mergeable> hocon::config_value::with_fallback ( std::shared_ptr< const config_mergeable > other ) const

overridevirtualinherited

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 config_object 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.

Parameters

other an object whose keys should be used as fallbacks, if the keys are not present in this one

Returns: a new object (or the original one, if the fallback doesn't get used)

Implements hocon::config_mergeable.

◆ with_origin()

virtual shared_value hocon::config_value::with_origin ( shared_origin origin ) const

virtualinherited

Returns a.

config_value

based on this one, but with the given origin. This is useful when you are parsing a new format of file or setting comments for a single config_value.

Parameters

origin the origin set on the returned value

Returns: the new config_value with the given origin
