Member Function Documentation

AddPyramidLevelCondition()

void imgdoc2::CTileInfoQueryClause::AddPyramidLevelCondition ( LogicalOperator  logical_operator, ComparisonOperation  comparison_operation, int  value  )

inline

Adds a condition for the pyramid level. This condition is added to the end of the internal list of conditions.

Parameters

logical_operator	The logical operator.
comparison_operation	The comparison operation.
value	The value.

GetPyramidLevelCondition()

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

inlineoverridevirtual

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.
