SWbemRpnEncodedQuery structure (wmiutils.h)

The SWbemRpnEncodedQuery structure contains information from the IWbemQuery::GetAnalysis method when you use the WMIQ_ANALYSIS_RPN_SEQUENCE analysis type. Not all the fields in the structure are used actively, because some are reserved for future use.

Members

m_uVersion

Unused. Value is always 1.

m_uTokenType

Unused. Value is always 0 (zero).

m_uParsedFeatureMask

Unused. Value is always 0 (zero).

m_uDetectedArraySize

Unused. Value is always 0 (zero).

m_puDetectedFeatures

Unused. Value is always NULL.

m_uSelectListSize

Number of elements listed in a SELECT clause. For example, in the statement SELECT a,b,c FROM d, m_uSelectListSize is the value 3 (a, b and c).

m_ppSelectList

Structure used to store property names. This field is used with the m_uSelectListSize field. For example, in the statement SELECT a,b,c FROM d, m_uSelectListSize is 3, and the m_ppszNameList field of the m_ppSelectList structure contains the strings "a", "b" and "c". For more information, see SWbemQueryQualifiedName.

m_uFromTargetType

Bitmap used to indicate the form of the FROM clause.

WMIQ_RPN_FROM_UNARY (1 (0x1))

FROM clause contains a single class.

WMIQ_RPN_FROM_PATH (2 (0x2))

FROM clause contains an object path.

WMIQ_RPN_FROM_CLASS_LIST (4 (0x4))

FROM clause contains a list of classes.

m_pszOptionalFromPath

Optional FROM path. If not used this field is NULL.

m_uFromListSize

Number of items in the FROM clause of the SELECT statement. For example, in the statement, SELECT * FROM a, b, the value of m_uFromListSize is 2.

m_ppszFromList

Pointer to a list of strings. Each string is one element of the FROM clause of a SELECT statement. For example, in the statement SELECT * FROM a, b, the list contains the strings "a" and "b".

m_uWhereClauseSize

Number of tokens in the WHERE clause. For example, in the statement SELECT * FROM a, b WHERE c < 1000 AND d ISA e, the value of m_uWhereClauseSize is 2 (the phrases c < 1000 and d ISA e).

m_ppRpnWhereClause

SWbemRpnQueryToken SELECT * FROM a, b WHERE c < 1000 AND d ISA e c < 1000 d ISA e AND

m_dblWithinPolling

If there is a WITHIN clause, this field indicates the polling interval. If there is a GROUP WITHIN clause, this m_dblWithinPolling is unused.

m_dblWithinWindow

Used if there is a GROUP WITHIN clause to indicate the interval over which to group results.

m_uOrderByListSize

m_ppszOrderByList

m_uOrderDirectionEl
