Detailed Description

DataFilter array providing some convenience functions.

Note

For features the meta data filtering works on the MetaDataInterface of the Feature. For peaks it works on the FloatDataArrays defined in MSSpectrum.

Member Enumeration Documentation

FilterOperation

enum FilterOperation

Filter operation.

Enumerator
GREATER_EQUAL	Greater than the value or equal to the value.
EQUAL	Equal to the value.
LESS_EQUAL	Less than the value or equal to the value.
EXISTS	Only for META_DATA filter type, tests if meta data exists.

FilterType

enum FilterType

Information to filter.

Enumerator
INTENSITY	Filter the intensity value.
QUALITY	Filter the overall quality value.
CHARGE	Filter the charge value.
SIZE	Filter the number of subordinates/elements.
META_DATA	Filter meta data.

Member Function Documentation

add()

void add

(

const DataFilter &

filter

)

Adds a filter.
