getColumnNames
public java.util.List<java.lang.String> getColumnNames()
Description copied from interface:Dataset
Returns an unmodifiable list of this dataset's column names, in order.- Specified by:
getColumnNames
in interfaceDataset
-
getColumnTypes
public java.util.List<java.lang.Class<?>> getColumnTypes()
Description copied from interface:Dataset
Returns an unmodifiable list of this dataset's column types, in order.- Specified by:
getColumnTypes
in interfaceDataset
-
getColumnCount
public int getColumnCount()
Description copied from interface:Dataset
Returns the number of columns.- Specified by:
getColumnCount
in interfaceDataset
-
getRowCount
public int getRowCount()
Description copied from interface:Dataset
Return the number of rows in this dataset- Specified by:
getRowCount
in interfaceDataset
-
getColumnIndex
public int getColumnIndex(java.lang.String name)
Description copied from interface:Dataset
Returns the index of the given column, case insensitive- Specified by:
getColumnIndex
in interfaceDataset
- Parameters:
name
- the name of the column to look upw- Returns:
- the index of the column
-
getColumnName
public java.lang.String getColumnName(int col)
Description copied from interface:Dataset
Returns the name of the given column.- Specified by:
getColumnName
in interfaceDataset
-
getColumnType
public java.lang.Class<?> getColumnType(int col)
Description copied from interface:Dataset
Returns the type of the given column.- Specified by:
getColumnType
in interfaceDataset
-
getValueAt
public java.lang.Object getValueAt(int row, int col)
Description copied from interface:Dataset
Returns the value in the dataset at the given location.- Specified by:
getValueAt
in interfaceDataset
-
getQualityAt
public QualityCode getQualityAt(int row, int col)
Description copied from interface:Dataset
Returns the quality of the value at the given location.- Specified by:
getQualityAt
in interfaceDataset
-
getValueAt
public java.lang.Object getValueAt(int row, java.lang.String colName)
Description copied from interface:Dataset
Returns the value at the given row and at a column named colName. Column name matching is case insensitive.- Specified by:
getValueAt
in interfaceDataset
-
getPrimitiveValueAt
public double getPrimitiveValueAt(int row, int col)
Description copied from interface:Dataset
If the given column is a numeric type or a Date, then the value will be returned as a double. (Charts uses this functionality to provide a seamless interface with certain optimized dataset implementations.- Specified by:
getPrimitiveValueAt
in interfaceDataset
-
binarySearch
public int binarySearch(int column, java.lang.Object key)
Description copied from interface:Dataset
Performs a binary search on the specified column, looking for the specified key. Column MUST be sorted in ascending order. Dataset provides an inefficient default implementation of binary search that allocates a new array list for the entire column.- Specified by:
binarySearch
in interfaceDataset
- Returns:
- index of the search key, if it is contained in the list; otherwise, (-(insertion point) - 1). The insertion point is defined as the point at which the key would be inserted into the list: the index of the first element greater than the key, or list.size(), if all elements in the list are less than the specified key. Note that this guarantees the return value will be greater than or equal to 0, but only if the key is found.
