Member Function Documentation

GetPyramidLevelCondition()

virtual bool imgdoc2::ITileInfoQueryClause::GetPyramidLevelCondition ( int  no, LogicalOperator *  logical_operator, ComparisonOperation *  comparison_operation, int *  value  ) const

pure virtual

Gets a condition for the pyramid-level property. The conditions on this property are to be numbered 0 to n-1, where n is the number of conditions. If calling this method with an argument "no" larger than n-1, the method must return false. This method is required to be idempotent, if called multiple times (with same arguments) it must give the same result. Note that the logical operator of the condition with index 0 is unused.

Parameters

	no	The 0-based index of the condition being queried.
[out]	logical_operator	If non-null and the operation is successful, the logical operator is placed here.
[out]	comparison_operation	If non-null and the operation is successful, the comparison operation is placed here.
[out]	value	If non-null and the operation is successful, the value for the comparison operation is placed here.

Returns

True if it succeeds, false if it fails.

Implemented in imgdoc2::CTileInfoQueryClause.
