方法详细资料
-
globalInfo
Returns a string describing this filter- 返回:
- a description of the filter suitable for displaying in the explorer/experimenter gui
-
getCapabilities
Returns the Capabilities of this filter.- 指定者:
getCapabilities
在接口中CapabilitiesHandler
- 覆盖:
getCapabilities
在类中Filter
- 返回:
- the capabilities of this object

setInputFormat
Sets the format of the input instances.- 覆盖:
setInputFormat
在类中Filter
- 参数:
instanceInfo
- an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required).- 返回:
- true if the outputFormat may be collected immediately
- 抛出:
Exception
- if something goes wrong
-
input
Input an instance for filtering. Ordinarily the instance is processed and made available for output immediately. Some filters require all instances be read before producing output.- 覆盖:
input
在类中Filter
- 参数:
instance
- the input instance- 返回:
- true if the filtered instance may now be collected with output().
- 抛出:
IllegalStateException
- if no input format has been defined.
-
toSource
Returns a string that describes the filter as source. The filter will be contained in a class with the given name (there may be auxiliary classes), and will contain two methods with these signatures:
where the array// converts one row public static Object[] filter(Object[] i); // converts a full dataset (first dimension is row index) public static Object[][] filter(Object[][] i);
i
contains elements that are either Double, String, with missing values represented as null. The generated code is public domain and comes with no warranty. -
getRevision
Returns the revision string.- 指定者:
getRevision
在接口中RevisionHandler
- 覆盖:
getRevision
在类中Filter
