The AbleDataSource interface is implemented to provide common information about data sources, the records they provide, and the fields contained by those records. When a data source is opened, it is required to create a vector of AbleFields.
Method Summary | |
---|---|
void |
close()
Set the number of records in the data source |
int |
getBufferSize()
Get the current buffer size, the number of records to cache. |
java.util.Vector |
getFieldList()
Return a Vector of AbleFields describing this datasource. |
int |
getNumFieldsPerRec()
Returns the number of fields in each record in the data source. |
long |
getNumRecords()
Returns the number of records in the data source. |
java.util.Vector |
getTextData()
Return a vector of text data records. |
boolean |
isAllNumericData()
Returns true if all fields are "continuous" or "discrete" false if any are "categorical" (i.e. |
boolean |
isReady()
Returns whether the data source is ready to be opened. |
void |
open()
Returns the number of records in the data source |
void |
readNextRecordBlock()
Read the next block of records from the data source. |
void |
setBufferSize(int size)
Get the current buffer size, the number of records to cache. |
void |
setFieldList(java.util.Vector fieldList)
Set a Vector of AbleFields describing this datasource. |
