value the value to bind

public void bind (int index, double value)

Bind the value to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind
value the value to bind

public void bind (int index, int value)

Bind the value to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind
value the value to bind

public void bind (int index, String value)

Bind the value to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind
value the value to bind

public void bind (int index, long value)

Bind the value to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind
value the value to bind

public void bind (int index, byte[] value)

Bind the value to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind
value the value to bind

public void bind (int index, boolean value)

Bind the value to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind
value the value to bind

public void bindNull (int index)

Bind null to an index. A prepareForInsert() or prepareForReplace() without a matching execute() must have already have been called.

Parameters
index the index of the slot to which to bind

public void close ()

Close this object and release any resources associated with it. The behavior of calling insert() after calling this method is undefined.

public long execute ()

Execute the previously prepared insert or replace using the bound values since the last call to prepareForInsert or prepareForReplace.

Note that calling bind() and then execute() is not thread-safe. The only thread-safe way to use this class is to call insert() or replace().

Returns
  • the row ID of the newly inserted row, or -1 if an error occurred

public int getColumnIndex (String key)

Returns the index of the specified column. This is index is suitagble for use in calls to bind().

Parameters
key the column name
Returns
  • the index of the column

public long insert (ContentValues values)

Performs an insert, adding a new row with the given values. If the table contains conflicting rows, an error is returned.

Parameters
values the set of values with which to populate the new row
Returns
  • the row ID of the newly inserted row, or -1 if an error occurred

public void prepareForInsert ()

Prepare the InsertHelper for an insert. The pattern for this is:

  • prepareForInsert()
  • bind(index, value);
  • bind(index, value);
  • ...
  • bind(index, value);
  • execute();

public void prepareForReplace ()

Prepare the InsertHelper for a replace. The pattern for this is:

  • prepareForReplace()
  • bind(index, value);
  • bind(index, value);
  • ...
  • bind(index, value);
  • execute();

public long replace (ContentValues values)

Performs an insert, adding a new row with the given values. If the table contains conflicting rows, they are deleted and replaced with the new row.

Parameters
values the set of values with which to populate the new row
Returns
  • the row ID of the newly inserted row, or -1 if an error occurred
