mozIStorageValueArray

mozIStorageValueArray wraps an array of SQL values, such as a single database
row.

Methods

getTypeOfIndex(aIndex)

Returns the type of the value at the given column index;
one of VALUE_TYPE_NULL, VALUE_TYPE_INTEGER, VALUE_TYPE_FLOAT,
VALUE_TYPE_TEXT, VALUE_TYPE_BLOB.

getInt32(aIndex)

Obtain a value for the given entry (column) index.
Due to SQLite’s type conversion rules, any of these are valid
for any column regardless of the column’s data type. However,
if the specific type matters, getTypeOfIndex should be used
first to identify the column type, and then the appropriate
get method should be called.

If you ask for a string value for a NULL column, you will get an empty
string with IsVoid set to distinguish it from an explicitly set empty
string.

getInt64(aIndex)

getDouble(aIndex)

getUTF8String(aIndex)

getString(aIndex)

getBlob(aIndex, aDataSize, aData)

getIsNull(aIndex)

getSharedUTF8String(aIndex, aLength, aResult)

Returns a shared string pointer

getSharedString(aIndex, aLength, aResult)

getSharedBlob(aIndex, aLength, aResult)

Attributes

numEntries

number of entries in the array (each corresponding to a column
in the database row)

to indicate what type of value is present at
