◆ LDContextBuilder_AddKind()

LDContextBuilder_AddKind	(	LDContextBuilder	builder,
		char const *	kind,
		char const *	key
	)

Add a kind instance to the context builder. The kind will have the specified key.

Attributes may be set for the kind by calling the LDContextBuilder_Attributes_* methods with the same "kind".

You must first add the kind to the context builder before setting attributes.

If you call this a second time, with an already specified kind, but a different key, then the key for that kind will be updated.

Parameters

builder	The builder to add the kind to. Must not be NULL.
kind	The kind to add. Must not be NULL.
key	The key for that kind. Must not be NULL.

◆ LDContextBuilder_Attributes_AddPrivateAttribute()

LDContextBuilder_Attributes_AddPrivateAttribute	(	LDContextBuilder	builder,
		char const *	kind,
		char const *	attr_ref
	)

Designate a context attribute, or properties within them, as private: that is, their values will not be sent to LaunchDarkly in analytics events.

Each parameter can be a simple attribute name, such as "email". Or, if the first character is a slash, the parameter is interpreted as a slash-delimited path to a property within a JSON object, where the first path component is a Context attribute name and each following component is a nested property name: for example, suppose the attribute "address" had the following JSON object value:

{"street": {"line1": "abc", "line2": "def"}}

Using ["/address/street/line1"] in this case would cause the "line1" property to be marked as private. This syntax deliberately resembles JSON Pointer, but other JSON Pointer features such as array indexing are not supported for Private.

This action only affects analytics events that involve this particular context. To mark some (or all) context attributes as private for all contexts, use the overall configuration for the SDK. See

LDServerConfigBuilder_Events_AllAttributesPrivate
LDClientConfigBuilder_Events_AllAttributesPrivate

and

LDServerConfigBuilder_Events_PrivateAttribute
LDClientConfigBuilder_Events_PrivateAttribute

The attributes "kind" and "key", and the "_meta" attributes cannot be made private.

Parameters

builder	The builder. Must not be NULL.
kind	The kind to set the attribute as private for. Must not be NULL.
attr_ref	An attribute reference. Must not be NULL.

◆ LDContextBuilder_Attributes_Set()

LDContextBuilder_Attributes_Set	(	LDContextBuilder	builder,
		char const *	kind,
		char const *	attr_name,
		LDValue	val
	)

Add or update a top-level attribute in the specified kind.

Adding a LDValue to the builder will consume that value. You should not access the value after adding it to the builder, and you do not need to call LDValue_Free on the value.

Parameters

builder	The builder. Must not be NULL.
kind	The kind to add the attribute to. Must not be NULL.
attr_name	The name of the attribute to add. Must not be NULL.
val	The value of the attribute to add. Must not be NULL.

◆ LDContextBuilder_Attributes_SetAnonymous()

LDContextBuilder_Attributes_SetAnonymous	(	LDContextBuilder	builder,
		char const *	kind,
		bool	anonymous
	)

Set the anonymous attribute for the specified kind.

If true, the context will not appear on the Contexts page in the LaunchDarkly dashboard.

Parameters

builder	The builder. Must not be NULL.
kind	The kind to set the anonymous attribute for. Must not be NULL.
anonymous	The value to set the anonymous attribute to.

◆ LDContextBuilder_Attributes_SetName()

LDContextBuilder_Attributes_SetName	(	LDContextBuilder	builder,
		char const *	kind,
		char const *	name
	)

Set the name attribute for the specified kind.

You can search for contexts on the LaunchDarkly Contexts page by name.

This method will make a copy of the name string, and the caller remains responsible for the original name string.

Parameters

builder	The builder. Must not be NULL.
kind	The kind to set the name for. Must not be NULL.
name	The name to set. Must not be NULL.

◆ LDContextBuilder_Attributes_SetPrivate()

LDContextBuilder_Attributes_SetPrivate	(	LDContextBuilder	builder,
		char const *	kind,
		char const *	attr_key,
		LDValue	val
	)

Add or update a private attribute. Once an attribute has been set as private using this method it will remain private.

A subsequent call to LDContextBuilder_Attributes_Set, for the same attribute, will not remove the private status.

This method cannot be used to set the key, kind, name, or anonymous property of a context.

Adding a LDValue to the builder will consume that value.

You should not access the value after adding it to the builder, and you do not need to call LDValue_Free on the value. This method is just a convenience which also adds the attribute to the private attributes list, as if using LDContextBuilder_Attributes_AddPrivateAttribute.

Parameters

builder	The builder. Must not be NULL.
kind	The kind to set the private attribute for. Must not be NULL.
attr_key	The key of the private attribute. Must not be NULL.
val	The value of the private attribute. Must not be NULL.

◆ LDContextBuilder_Build()

LDContextBuilder_Build ( LDContextBuilder builder )

Construct a context from a context builder.

When building a context using LDContextBuilder_Build the builder will be consumed and you do not need to call LDContextBuilder_Free.

Parameters

builder The builder to build a context from. Must not be NULL.

Returns: The built context.

◆ LDContextBuilder_Free()

LDContextBuilder_Free ( LDContextBuilder builder )

Free a context builder.

This method only needs to be used when not building the context. If you use LDContextBuilder_Build, then the builder will be consumed, and you do not need to call LDContextBuilder_Free.

Parameters

builder The builder to free.

◆ LDContextBuilder_New()

LDContextBuilder_New ( )

Create a new context builder.

Returns: A new context builder instance.
