Method Detail

end

void end()

This method deletes the invoking implementation. That is, it frees all the resources used by the invoking object. After a call to this method, you cannot use the invoking extractable object again.

getSize

int getSize()

This method is used to determine the size of the invoking array.

Returns:

An integer specifying the size of the invoking array. An empty array has size 0 (zero).

getColumnName

java.lang.String getColumnName(int index)

This method is used to determine the definition of a column referenced by index.

Returns:

The column name of index.

getName

java.lang.String getName()

This method returns the name of the schema.

getColumnIndex

int getColumnIndex(java.lang.String name)

This method returns the index of a named column.

Parameters:

name - The name of the column for which you want to retrieve the index.

Returns:

The index of the named column. Throws an exception if the column does not exist.

isInt

boolean isInt(int index)

This method is used to determine whether a column contains integer values.

Parameters:

index - The index of the column you want to check.

Returns:

A boolean value specifying whether the indexed column contains integer values.

isNum

boolean isNum(int index)

This method is used to determine whether a column contains float values.

Parameters:

index - The index of the column you want to check.

Returns:

A boolean value specifying whether the indexed column contains float values.

isSymbol

boolean isSymbol(int index)

This method is used to determine whether a column contains string values.

Parameters:

index - The index of the column you want to check.

Returns:

A boolean value specifying whether the indexed column contains string values.

isTuple

boolean isTuple(int index)

This method is used to determine whether a column is a subtuple column.

Parameters:

index - The index of the column you want to check.

Returns:

A boolean value specifying whether the column is a subtuple column.

isIntCollection

boolean isIntCollection(int index)

This method is used to determine whether a column is an integer collection column.

Parameters:

index - The index of the column you want to check.

Returns:

A boolean value specifying whether the column is an integer collection column.

isNumCollection

boolean isNumCollection(int index)

This method is used to determine whether a column is a float collection column.

Parameters:

index - The index of the column you want to check.

Returns:

A boolean value specifying whether the column is a float collection column.
