UI_GetNodeFromExpression()

uiNode_t* UI_GetNodeFromExpression	(	uiAction_t *	expression,

		const value_t **	property
	)

Get a node and a property from an expression.

Parameters

	expression	Expression tree to analyse
	context	Call context
[out]	property	A node property

Returns

A node (else nullptr, if no node found) and a property (else nullptr if no/wrong property defined)

UI_GetStringFromExpression()

const char* UI_GetStringFromExpression	(	uiAction_t *	expression,
		const uiCallContext_t *	context
	)

Returns

A string, else an empty string

Todo:

this should not work very well, because too much va are used then we should locally cache values, or manage a temporary string structure

Todo:

should we add a delta?

UI_ParseValueExpression()

static uiAction_t* UI_ParseValueExpression ( const char **  text )

static

Read a value from the stream and init an action with it.

Returns

An initialized action else nullptr

Todo:

when it is possible, we must check range of param id

Todo:

We MUST remove the OLD code as fast as possible

Todo:

use a better check - e.g. Com_ParseValue with V_INT or V_FLOAT
