Field Detail

columnLabels

protected final java.lang.String[] columnLabels

The labels of the columns of this MemoryResultSet. These are usually provided via ResultSetMetaData.getColumnLabel(int).

columnTypes

protected final ProcessConstants.AdeptDataType[] columnTypes

The data types of the columns of this MemoryResultSet. Each AdeptDataType is the type that corresponds closest to the corresponding SQL type.

values

protected final java.util.List<java.io.Serializable[]> values

A list of values where each list entry corresponds to a row. The type of the values are the Java-types corresponding to the AdeptDataType of the column.

Constructor Detail

MemoryResultSetImpl

public MemoryResultSetImpl(java.lang.String[] columnLabels,
                           ProcessConstants.AdeptDataType[] columnTypes)

Creates a new MemoryResultSet with the designated column labels and types. Note that both arrays need to correspond, especially they need to have the same size.

Parameters:

columnLabels - The labels of the columns of the created MemoryResultSet.

columnTypes - The types (as AdeptDataType) of the columns of the created MemoryResultSet.

MemoryResultSetImpl

public MemoryResultSetImpl(java.util.List<java.lang.String> columnLabels,
                           java.util.List<ProcessConstants.AdeptDataType> columnTypes)

Creates a new MemoryResultSet with the designated column labels and types. Note that both lists need to correspond, especially they need to have the same size.

Parameters:

columnLabels - The labels of the columns of the created MemoryResultSet.

columnTypes - The types (as AdeptDataType) of the columns of the created MemoryResultSet.

MemoryResultSetImpl

protected MemoryResultSetImpl(ProcessConstants.AdeptDataType[] columnTypes,
                              java.lang.String[] columnLabels)

Creates a new MemoryResultSet with the designated column labels and types. Note that both arrays need to correspond, especially they need to have the same size.
The order is of the parameters is changed to avoid problems with the existing method signature.

Parameters:

columnLabels - The labels of the columns of the created

columnTypes - The types (as AdeptDataType) of the columns of the created MemoryResultSet. MemoryResultSet.

Method Detail

addValues

public void addValues(java.io.Serializable[] row)

Adds the designated values as row at the end to this MemoryResultSet. Note that the designated array needs to have the right size (depending on the columns). Since the array is directly used, the caller must not change the array afterwards.

Parameters:

row - The row (array of values) to be added to this MemoryResultSet.

addValues

public void addValues(int index,
                      java.io.Serializable[] row)

Adds the designated values as row at the designated index to this MemoryResultSet. The previous row will be shifted towards the end. Note that the designated array needs to have the right size (depending on the columns). Since the array is directly used, the caller must not change the array afterwards.

Parameters:

index - The index at which to add the designated row and shift the existing row to the end.

row - The row (array of values) to be added to this MemoryResultSet at the designated index.

setValues

public void setValues(int index,
                      java.io.Serializable[] row)

Sets the values of the designated row to the designated values. The previous values will be replaced. Note that the designated array needs to have the right size (depending on the columns). Since the array is directly used, the caller must not change the array afterwards.

Parameters:

index - The index at which to replace the row with the designated values.

row - The row (array of values) to replace the current values of this MemoryResultSet at the designated index.

addValues

public void addValues(java.util.List<java.io.Serializable> row)

Adds the designated values as row at the end to this MemoryResultSet. Note that the designated list needs to have the right size (depending on the columns).

Parameters:

row - The row (list of values) to be added to this MemoryResultSet.

addValues

public void addValues(int index,
                      java.util.List<java.io.Serializable> row)

Adds the designated values as row at the designated index to this MemoryResultSet. The previous row will be shifted towards the end. Note that the designated list needs to have the right size (depending on the columns).

Parameters:

index - The index at which to add the designated row and shift the existing row to the end.

row - The row (list of values) to be added to this MemoryResultSet at the designated index.

setValues

public void setValues(int index,
                      java.util.List<java.io.Serializable> row)

Sets the values of the designated row to the designated values. The previous values will be replaced. Note that the designated list needs to have the right size (depending on the columns).

Parameters:

index - The index at which to replace the row with the designated values.

row - The row (list of values) to replace the current values of this MemoryResultSet at the designated index.

Specified by:

getRowCount in interface MemoryResultSet

Returns:

The amount of rows of this memory result set.

getColumnLabel

public java.lang.String getColumnLabel(int column)

Description copied from interface: MemoryResultSet

Gets the label for the designated column. The column has to be >= 0 and <MemoryResultSet.getColumnCount().
