Detailed Description

Simple string to cVariant evaluation. no complex expressions. e.g. no math operators. No methods called, etc. This can be overridden by cExpressionExec to give lots more functionality.

Member Function Documentation

◆ GetArrayListRef()

HRESULT GrayLib::cExpressionBase::GetArrayListRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  vValRet,
ITERATE_t  nAppendStart = 0 
)

Parse a string for a list of comma separated args. put_StrExpUnk Parse the output from GetStrArray(); Don't assume it is [blocked]. Terminates on any bad syntax or end type character.

  • nAppendStart = append to this array starting at this position.
    Returns
    >= 0 = Number of elements.

◆ GetArrayRef()

HRESULT GrayLib::cExpressionBase::GetArrayRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  vValRet,
ITERATE_t  nAppendStart = 0 
)

get array. assume it is [blocked].

Returns
>= 0 = Number of elements.

◆ GetMapElementName()

HRESULT GRAYCALL GrayLib::cExpressionBase::GetMapElementName ( const ATOMCHAR_t *&  rpszExp,
OUT cStringA &  rsName 
)
static

◆ GetMapListRef() [1/2]

HRESULT GrayLib::cExpressionBase::GetMapListRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  rMapRet 
)

Don't assume it is {blocked}.

◆ GetMapListRef() [2/2]

HRESULT GrayLib::cExpressionBase::GetMapListRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVarMap &  rMapRet 
)

Parse a list of mapped "Name: Value" paired items. separated by commas. Don't assume it is {blocked}. Terminates on any bad syntax or end type character. Convert to array if names are omitted??

◆ GetMapRef() [1/2]

HRESULT GrayLib::cExpressionBase::GetMapRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  vValRet 
)

Parse a list of mapped "Name : Value" paired items. separated by commas. assume it is {blocked}. Convert to array if names are omitted??

◆ GetMapRef() [2/2]

HRESULT GrayLib::cExpressionBase::GetMapRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVarMap &  rMapRet 
)

Parse a list of mapped "Name : Value" paired items. separated by commas. assume it is {blocked}. Convert to array if names are omitted??

◆ GetSimpleVarRef()

HRESULT GRAYCALL GrayLib::cExpressionBase::GetSimpleVarRef ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  vValRet 
)
static

Parse a single value. not an expression. Simple string to var evaluation. no complex expressions. e.g. no math operators.

Returns
a double,float,DWord, or int depending on the string.
S_FALSE = not a simple number. its something else. Advances rpszExp past the parsed stuff.

◆ GetStringRefQ()

HRESULT GRAYCALL GrayLib::cExpressionBase::GetStringRefQ ( const ATOMCHAR_t *&  rpszExp,
OUT cStringA &  rsRet 
)
static

Get quoted string. remove quotes. find closing quote.

Returns
Length consumed from source expression until the ending quote.

◆ GetStringRefV()

HRESULT GRAYCALL GrayLib::cExpressionBase::GetStringRefV ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  rvValRet 
)
static

Get quoted string

Returns
0 = ok.

◆ GetVar() [1/2]

cVariant GrayLib::cExpressionBase::GetVar ( const ATOMCHAR_t *  pszExp)
inline

This version doesn't advance the pszExp pointer.

◆ GetVar() [2/2]

HRESULT GrayLib::cExpressionBase::GetVar ( const ATOMCHAR_t *  pszExp,
OUT cVariant &  vValRet 
)
inline

This version doesn't advance the pszExp pointer.

◆ GetVarRef()

cVariant GrayLib::cExpressionBase::GetVarRef ( const ATOMCHAR_t *&  rpszExp)
inline

Advances rpszExp past the parsed stuff.

◆ GetVarRef2()

HRESULT GrayLib::cExpressionBase::GetVarRef2 ( const ATOMCHAR_t *&  rpszExp,
OUT cVariant &  vValRet,
bool  bInArray 
)
virtual

Base string to var evaluation. no complex expressions and no math operators. Override as cExpressionExec for that. opposite of cVariantData::GetStrExpT

  • Advances rpszExp past the parsed stuff. This will strip quotes, etc. similar to cExpressionExec
  • bInArray = parsing member of array. has extra delimiters. Is this really an int,float,string or should it stay an expression? only quoted strings are true strings anything else should be an expression or other obvious type. Leave as VARTYPE_StringExp if it cannot be easily classified.

Reimplemented in GrayLib::cExpressionExec.

◆ IGNORE_WARN_ABSTRACT()

GrayLib::cExpressionBase::IGNORE_WARN_ABSTRACT ( cExpressionBase  )

◆ IsParenNeeded()

bool GRAYCALL GrayLib::cExpressionBase::IsParenNeeded ( const ATOMCHAR_t *  pszExp)
static

◆ UNITTEST_FRIEND()

GrayLib::cExpressionBase::UNITTEST_FRIEND ( cExpressionBase  )
